It Is highly fortunate that Senator Bacon’s sober counsel has prevailed against the 111-tlmed Clark resolution which, had It been adopted, would at least _ have embarrassed the President and his advisers.In their efforts to untangle the serious Mexican situation. This resolution demanded an Immediate Inquiry Into conditions In Mexico by the Foreign Relations com mittee of the Senate, independent of that which Presi dent Wilson Is now conducting and It opened the way to Independent action on the part of Congress. Seator Bacon, who is chairman of the Foreign Re- | lations committee vigorously op; csed such a move | on the ground that It would tend merely to complicate an already difficult pioblem. He called attention to 1 the fact that the President has sent a personal repre- , sentative to Mexico in the hope of bringing about some understanding whereby p ace and orderly gov ernment may be restored and that until this effort had proved unmistakably futile and other well-con sidered and pacific p.ans of the ad: illustration had failed, there should be no hasty interference. There are two ways, as enator Bacon declared, by which the United States may proceed to meet its responsi bilities In this l ying situation- "One way is to at tempt to do s" 1 .. omer . by the strong arm, by force. Who will say that the latter should not he the last to which we should resort?” The administration’s policy toward Mexico thus far has been thoroughly justified and Is approved both in and out of Congress by thoughtful men Irre spective of party. The time has nov evidently come when some decisive move must be made, but for that very reason It should made deliberately and with full knowledge of all the circumstances. To this end, the President has sent to Mexico as his personal rep resentative "Mr. John Lind, whose mission It Is to gather accurate information of conditions in that country and also, if possible, to effect some plan of peaceful agreement among the warring factions. The reported declaration of the Huerta govern ment that -it will not receive Mr. Lind unless he comes In the capacity of an ambassador, officially recognizing the Huerta regime, has given rise to much concern. It may be, however, that what ap pears now to be a dangerous difficulty will dwindle to Insignificance. It Is scarcely credible that Huerta would flatly ignore or insult the President’s special representative who comes in a capacity really much higher, if not more responsible, than that of any am bassador. Furthermore, as has been pointed out, Mr. Lind’s status in the Mexican capital will not depend upon his direct relationships to the de facto govern ment there. “He has gone,” as The Journal’s Wash ington correspondent points out, “in the capacity of adviser to the American embassy and whatever he may have to say t. Mr. Huerta may be said through the official in charge of the embassy, one astute in dividual named Nelson ’OShaughnessy.” Whether the Lind mission succeeds or fails re mains to be seen. For the present, however, it is clear that the wisest course the United States can pur sue is that w-hlch the administration has adopted and which it is following in a manner that merits full and cordial confidence. The New Balkan Treaty. Whether the treaty agreed to by the Balkan Allies will bring real peace or will merely affoi-d a short breathing space in which the warring States will gird themselves for another fierce conflict is a matter of surmise. The terms of the tentative settlement seem to be unsatisfactory to all the parties concerned ex cept Rumania. Bulgaria has been allotted more of northern Macedonia than Servia and Greece wished to allow her. At the same time Bulgaria is sharply piqued over being deprived of other important terri tory to which she has laid claim and particularly does she object to being assigned the task of ex pelling, unaided, the Turks from Adrianople. Ru mania, who took no part in the original Ottoman war, gains most from the new treaty; and it was her threat to hurl an army forthwith against Sofia, the Bulgarian capital, that forced an acceptance of the modified frontier. In these circumstances it is possible that the Al lies will renew their internal warfare, though if the European Powers approve and sustain the terms of 'the treaty, or those of some subsequent treaty, it is likely that neace will be restored in fact. The .,ig- nificant aspect of the new arrangement is the weaken ed condition in which it leaves Bulgaria atid the indi rect, though impftant, bearing this wil/ have on the affairs of the entire Balkan peninsula. Until the recent war Bulgaria was clearly dominant among her neighbors. But she must now give full recognition to the rights and the influence of Servia and Greece and even of Montenegro. If there is to be a Balkan con federacy at all, it must be founded on an equality of Interests and its maintenance will require nicely , balanced co-operation among its component States. Nothing stingy about Uncle Sam when it comes kto moving the crops. The “Syndicated” War Scare. There is a persistent and seemingly concerted ef fort to force the United States into a ‘Mexican war despite the administration’s well-considered and well conducted plans to effect a peaceful settlement of the grave issues involved. Whence comes this pell-mell spirit tl{at does not pause to weigh the human cost nor to avert, if possible, the farflung problems which such a conflict would entail? Certainly, It does not come from the rank and file of our thoughtful, pa triotic citizens. Evidently it proceeds from interests which are seeking war as a means to advance their own selfish and sinister ends. Senator Williams, of Mississippi, in addressing the Senate yesterday declared it to be his deliberate opin ion that there is now “an organized and syndicated movement to bring about war between the United States and Mexico, organized and syndicated through newspapers with money behind it, and not all of it Mexican money.” His suspicion is by means ground less, for while the President and the State depart ment and the Foreign Relations committee of the Senate are exerting every effort to adjust our strain ed relationships toward the troublous country across the Rio Grande and are going the well-measured length of diplomatic counsel to avoid drastic pro cedure, we find, other influences doing all within their power to Inflame public feeling and to drive Congress to precipitate action. It Is assuring to know, however, that we have at the head of this Government statesmen who will not be rushed Into committing the nation to a war that can be averted on reasonable and honorable terms. And It is even more asuring to know that they are supported by the country’s sober and dominant thought. What the ultimate outcome of the Mexican situation may be is as yet beyond prediction. But up to the present hour, the administration’s course has been eminently proper. President Wilson and his advisers evidently have confidence in the mission of Mr. John Lind who has been sent to. the Mexican capital as the President’s special representative. That is apparently a decisive move on the part of our Government. Until the success or failure of this particular mission ic determined, there is no excuse for hasty action. The complications or perils which the jingoes dire- fully forecast will attend Mr. Lind's presence in Mexico are not likely to materialize. His status does not depend upon the recognition of the provisional government of Iluerta or upon that of the revolu tionary camps. He goes as adviser to the American embassy, through which he may present any plan he has to convey and conduct any negotiations he de sires. Huerta’s bark is more dreadful than his bite. The probability Is that he will think a long time be fore offering any affront to a special representative of the United States. If by any chance war with Mexico should be inev itable, it should come as a last resort, as the only possible means of preserving our national honor and of meeting our responsibilities to civilization; it should never come In response to the clamor of selfish interests. Such a war would not only burden the nation with a tremendous cost In money and lives; it would also set back those great causes of economic and political reform In which Congress Is now engaged and upon the success of which the peo ple’s welfare so vitally depends. It would mean a continuance and ev-.i an increase in the high cost of living; it would probably mean the Indefinite delay, if not the defeat of tariff revision, of banking and currency reform and of the country’s orderly progress along paths of business freedom and prosperity. Every American who regards his own interests and who truly loves his country -rill applaud the prudent, farsighted course which the administration is pursuing, a course which will protect our national welfare by peaceful mean j, so long as that is possi ble but which will be ready for honorable force, If need be. County Fairs. In commenting on the impressive list of county fairs which are to be held in Kentucky this year, the Louisville Courier-Journal pays a merited tribute to the value of this very old but now renascent in stitution. The typical county fair of today, it truly says, is first of all educational in purpose and is no longer to he regarded “merely as a medium of amusement.” Indeed, the clamorous fakirs and gaudy sideshows that monopolized the interest of fairs held some years ago are now becoming con spicuous by their absence or, at the most, are occupy ing a secondary place on the grounds, a fact which is distinctly advantageous to the larger and more wholesome purposes of the fair. The Courier-Jour nal remarks in this connection: “The county fair should he an exposition of county resources and a mirror of agricultural progress and domestic endeavor. By way of va riety amusement features are necessary but they should not be in such number as to overbalance or overshadow the serious business of the fair. . . The real county fair, agricultural, indus trial and mechanical, should never languish for lack of interest. Primarily the average fair is for. the benefit of the farmer and this is right and proper, fo*r practically every county is an agricultural county and the farm is the founda tion of general prosperity It is a noteworthy and highly gratifying fact that county fairs have been greatly on the increase in Georgia during the past few years. Their dis tinctive character varies with the locality. In some districts corn. exhibits are stressed, and everywhere such exhibits, are encouraged. In others, emphasis is laid on poultry and live stock. In still others truck products are especially interesting. In Cobb county a hay show is to be held this autumn. The significant thing is that so many individual counties or groups of counties are conducting these enter prises for the educational stimulus they will have on the immediate neighborhood. A State-wide fair is, to be sure, highly important and commend able, but these smaller fairs which are within reach of every farmer in their particular county or dis trict have a peculiarly direct and intensive value. A Farreaching Decision On Georgia Freight Rates. The recently announced decision of the Interstate Commerce Commission in the case of the Board of Trade of Carrollton against certain railroad compa nies of the Southeast marks an important step in the establishment of just and reasonable freight rates in Georgia. The relief it affords is not limited to a particular community, for the principles enunciated in this wholesome decision open the way to far- reaching readjustments in traffic rates throughout Georgia and, indeed, throughout the South. There appears elsewhere in today’s Journal an In teresting summary of the Commission’s ruling to gether with comment on its salient features by Mr. Edgar Watkins, of the firm of Watkins & Latimer, counsel for the Carrollton Board of Trade. To this «» clear account of the issues involved in the case, little need be added. As Mr. Watkins points out, Carrollton has been subjected to freight rates that were dis criminatory as wel. as excessive. Its shippers were charged rates which, in proportion to the distance concerned, were much higher than these charged competing points. Thus on many commodities the rates from Baltimore to Carrollton weVe actually higher than the rates on the same commodities mov ing over the same line and in the same direction to a point considerabl; beyond Carrollton; that is to say, a shipment which moved through Carrollton to the more distant point would be charged less than when it ended at Carrollton. This arbitrary manner of dealing, the roads sought to justify by contending that it was simply a logical application of the so-called “hasing-point” system. But Mr. Commissioner Clements disposes of this plea by holding that the basing point system of rate mak ing “does not now demand that joint through rates over long distances to local or non-competitive points should be made by adding to basing-point rates either the full locals or high differentials.” And he declares further In this connection that: “In the making of joint through rates on long distance traffic to local or non-eompetitive points, the differentials above the rates to the basing points should bear some reasonable relation to the total distance involved, in order that the rates to the local point may be just and to avoid subjecting such local points to prejudice or disadvantage that is undue,” The principle thus set forth is, indeed, significant. While recognizing natural basing points it affirms that “the rates charged towns other than basing points shall no longer be arbitraries but shall have reasonable relation 10 distance.” This solution, as Mr. Watkins says, “is conservative and wise and points the way to a closer approximation to rates based on the principle that the greater the distance freight moves, the greater the actual rate, though the rate per mile lessens with distance.” Following the decision In the Carrollton case and modeled upon the opinions therein set forth, is an other with reference to LaGrange and other Georgia towns similarly concerned. The relief thus granted amounts to far more than a reduction of excessive rates, It also lifts a burden of discriminatory rates which, after all, constitute the gravest of traffic evils. The development and prosperity of Georgia depend very largely on the protection of Its people against inequitable freight charges. The Commission’s de cision in these cases goes far toward the reform of existing inequalities and is, therefore, a distinct ad vantage to the common interests of the State. Give This Bill a Chance. It is commonly recognized that one of the most urgent public needs in Georgia. today is the estab lishment of a State bureau for the registration of vital statistics. A bill to this end has been favorably reported both in the House and the Senate and, if given its due place in the calendar, it will doubtless be passed at the present session of the Legislature. ^ A measure that so materially concerns the people’s health and their economic Interests as well deserves particularly generous consideration at the hands of the rules committee. Its passage will consume ap preciably no time, for there is no difference of opin ion as to its merits. It will not impede the progress of any other hill nor delay any other business. Surely, then, the Legislature can spare a few minutes for the enactment of a measure that will bring incalulable blessings to Georgia through all the years to come. The need and the value of a system of vital statis tics in conserving public health and in promoting the State’s practical interests are so obvious as to require little comment, suffice it to say that without an adequate and authentic record of births, deaths and the causes of deaths, scant progress can be made in campaigns against disease. One other important fact should be noted. Georgia now has no place or mention .n the health reports compiled and issued by the federal census bureau, simply for the reason that the bureau collects such statistics from only those States which have a satis factory system for the regitration of vital statistics. The only available records of this kind In Georgia are from the cities of Savannah and Atlanta. Thus in those reports of the Government which deal with health records and conditions and which are read as authoritative throughout the nation, .Georgia is conspicuous by her absence. This circumstance is a serious disadvantage to the State’s economic progress and development. The bill now awaiting passage is a model of its kind. It meets the requirements of the census bureau and the federal health authorities. Its enactment will mean the saving of money and He saving of lives. It should be given a place on the calendar and press ed to a speedy passage. THE BLOODY KNIFE BY BR. FRANK CRANB. (Copyright, 1913. by Frank Crane.) When a man acquires a peck of trouble it looks to him like a bushel and a half. We make a deal of pother and spend considerable sums of money toi secure for the children an education. By education we generally mean readin’, ’ritin’ and ’rithmetic, the three r’s, with a dash of the ologies. But a child gets much more body, mind and soul stuff out of his play than out of his study; which truth Emerson turned into an epigram: “The school boy learns more from the book un der the desk than from the book on the desk.” The acquisiton of the three r’s is carefully supervised by the teacher. At recess and be fore and after school the child is let run, and acts upon his own unguided initiative. It might be an interesting ex periment to call arithmetic and geography play, and to have the pupil make games of them, doing as he may be pleased; and to have the teacher take charge of his vacation hours and carefully manage his sports. Out in Gary, Ind., they do this. They have play ground teachers. It is much harder to teach children how to play than to see that,they work. For the former, it takes a natural born teaching genius and real child-love; any placeholder can do the latter. The essential element of efficiency in a teacher is the ability to make play out of work. In a toy shop in an American city there has re cently been offered for sale a wonderful plaything—a small, sharp Bowie knife, with a red splotch of paint on the blade representing blood. With these knives the little darlings can play bandit and robber with delightful realism. Who is there that can imagine a child can get in one hour’s Sunday school instruction enough antidote to counteract the moral effect of six days’ amusement with a bloody knife? The bloody knife stands for a whole series of forms of play that are demoralizing. In their street games children develop destructive tendencies. That seems to come by nature. Constructive and wholesome games, of building, devising and beautifying, could be made as interesting as murder, violence and theft; only they must be taught. # It is much the same with grown-ups. Our charac ter is determined more by our amusements than by our occupation. What sort of fun a man likes means vastly more b,y way of showing what kind of man he is, than the character of his work. The State—that is to say, the People—has never realized the importance of amusements. Is it not time to ask ourselves how we and our children are diverting ourselves, when we see imita tion blood-stained knives for sale in the shops?

This 10 per cent includes those who do the actual work of amusing; singers in grand opera, light opera, concert; actors in the “legitimate” theaters, in vaudeville, in burlesque, in small shows; performers in the various departments of the innumerable circuses, carnivals, street fairs, baseball players, football players, basket ball players, motor racers, aviators, boxers, innumerable exponents of innumerable forms of professional ath letics and professional sports. It includes also the people who promote these amuse ments; who incorporate companies and manufacture devices to be used in amusing—film companies with aimies of employes in the moving picture field, for ex ample; the people in their large office forces; the peo ple who manage and direct theaters, amusement parks, race courses, athletic fields, etc.; stage hands, mechan icians, electricians and employes in countless other ramifications of the general business of amusement. It includes •'Iso the people who promote these amuse- tainment, those who finance them, those who manage them, those who execute them, those press agents, ad vance men, sign painters, “spielers” and “bankers,” etc., who advertise them and draw the attention of the rest of us—the patrons who comprise the other 90 per cent.

The three largest aeroplanes ever ordered by the United States government are t 0 be delivered for final test l. These aeroplanes are for the use of the War department and are expected to include all that is newest and most practical in aeronautic construction. They are to be tested more .rigidly than have any other of the fly ing machines which have been purchased by the United States government. To secure the standards by which accurate al titude tests might be made, the bureau of standards has been experimenting for months with aneroid barometers, the instru ments by which altitudes have been measured by aviators from the beginning of the » science. These experiments give the surprising result that, ac cording to the most scientific test ever made in the world, no aneroid now in existence can be proved to be accurate. Consequently, every one of the world’s records for altitude may vary thousands of feet from' the truth. • • • The aneroid barometer Is a small instrument used for registering atmospheric pressure at different alti tudes. It was invented by Vidi, a French scientist, in Paris in 1848. The principle of the aneroid used for testing these great war aeroplanes does not differ from that of the original instrument used by Vidi. The aneroid has had comparatively little use until thet development of aviation. It was practically unknown outside of scientific circles. Travelers in unknown regions used it for testing mountain heights and at mospheric conditions, but it had no general use so, excepting to a few scientists it made little difference whether its registrations were accurate or not. ... As it is the only instrument known to register alti tude, the development of aviation called it into popu lar favor. When the war department prepared speci fied requirements for its aeroplanes the bureau of standards began to test the instruments by which the, altitude was to be measured. These tests have been most Intricate and careful. The results indicate Inac curacies which must interest the aviators of the world. Mayo D. Hersey, r '' the bureau of standards, who has| been in charge of the aneroid experiments, sailed for Germany last month. He will confer with a number| of European scientists who also have been studying this subject. An endeavor is to be made to determine' some means of perfecting the instrument so that its registrations may be depended upon A bulletin upon the subject of aneroids is now in course ot prepara-, tion by the bureau of standards and wlil issued in a 1 few months. • • • A collection of all the recognized makes of ane roid barometers in the world was secured by the bu reau of standards for making these tests. Each was subjected to the same rigid examination and experi ment. Specially designed apparatus was provided for raising and lowering the temperature to correspond with atmospheric changes at various altitudes. Sci entific observations of every change wer) taken /id- croscopically and recorded accurately for months. These records prove the great Inaccuracies of all of these instruments. It was difficult to secure two identical registrations from tne same instrument un der the same atmospheric conditions. , • • • The construction of the aneroid seems simple. Its basic principle is a hermetically sealed metal box from which the air has teen exhausted. The bottom and top of the box are slightly corrugated and of paper like thinness. The air exhaustion has been so complete) that they would fall together If permitted to take their natural position. To prevent this a strong spring is attached to the flexible top. When the pressure of the air is decreased by an ascending altitude, the spring relaxes and the top rises slightly. When the pressure Is increased by a descent the spring tightens and the delicate metal recedes a little. To the spring is attached a line thread-like chain attached to a lever which moves at each change In the atmospheric pres sure, thereby indicating the pulsation of the vacuum box. , • • • Many conditions affect the sensitiveness of the lit tle instrument, For instance, if a flying machine ascends at a high rate of speed, a greater decrease in the pressure of air will be noted by the aneroid than if the same altitude was achieved by a slower ascent. At present no means of making accurate allowance for discrepancies from this cause are known. The an eroid commonly used in aviation is supposed to be able to register an altitude of at least 15,000 feet. Thera is no certainty that it ever has done so. There is no method of determining absolutely whether or not any aeroplane ever rose to more than a fraction of the altitude accredited to it. It is also possible that the aneroid may not register at all after, a certain height, so that a daring aviator may have gone much higher -than his instrument Indicated. Consequently, this careful scientife test of the aneroids of the world indicates that every aviation altitude upon record is more apt to be wrong than right. • * • The three new war aeroplanes, now almost com pleted, are to be tested according to the strictest speci fications covering every point. Each must show a minimum speed not .falling below thirty-eight miles with a maximum of at least fifty-five miles an hour. It must be capable of a cross country run of 180 miles at an easy glide, and of executing a figue eight in the air in a rectangle of space not exceeding 600 by 250 feet without decreasing its altitude more than 100 feet. It must be able to carry a load of 450 pounds in addition to two persons, a pilot and an observer, besides sufficient oil and fuel for at least four hours. It must be equipped with engines capable of being throttled so that one person may operate the airship if need be. It must be capable of being shipped by road so that it cannot be more than ten feet wide in shipment and it must be so constructed that it can be made ready for operation in one hour, without re quiring the services of more than six men. • • • While these machines are all being built by Amer ican firms they are to be equipped with propelling power of foreign make. This is the first time this government has permitted any other than American r. achinery in an aeroplane designed for public use, and it is believed that the purchase of these now un der consideration will act as a stimulus to encourage the improvement of the aeronautic machinery of this country. The three engines selected are the Austro- Daimler, the Gnome and the Renault. The cost of each fully equipped aeroplane will approximate $10,000. ♦ • * The altitude requirement for each of these ma chines is to be an ascent of ,2,000 feet in ten minutes. As this altitude can only be measured by the aneroid, there is no means of knowing whether the new ma chines will comply with it or not. The aneroid which has been unofficially adopted for the testing of war aeroplanes consists of three parts which are enclosed in a black leather case resembling a tiny camera In appearance. The parts include the aneroid itself, con sisting of the vacuum box, spring and lever, the clock work which operates a registering apparatus and the register which includes a tiny roll of paper and a mi croscopic pencil. Instead of indicating the change* in atmospheric pressure by hands moving upon the face of the aneroid, this instrument marks them auto matically upon tne paper. Each sheet of paper is supposed to hold the registration of four hours changes, this being the proposed duration of a trip in an army aeroplane. The register attachment is a new development whic.t aviators commend because it is believed to be more accurate and more easily read than the old aneroid face. It gives the added ad vantage of furnishing a permanent record of altitude which can be produced at any time to Settle A dis puted point,
