4 S I 'r 1 humanfiictar in AirplaneAcciclsnts Cadets San Fliers, Not German Agents, Are Re sponsible for Most Falls HE officers aud cadets of the Hying fields that are scattered tlilckly over Texas do not share the belief of Senator Overman aud a good many others that Teuton ugwiis in airplane plants are responsive for any of the deaths by accident among them. They say they do not know anything about condi tions in airplane factories and therefore do not know whether or not lils assertions about the num of Germans employed therein are true, but they are skeptical about the senator's fears and allegations. Tlicy think they know a good deal about the causes of the many accidents, both fatal and unimportant, that have occurred during the last six months, says a writer in the New York Times' magazine section. And they declare very positively that not one of these accidents has been due to faulty construction or to enemy tam pering with the machinery. They say that In every case, thus far, the cause for the accident was to be found in the man himself and not In the machine he was driving. Among the flyers the conviction is strong that even if the machinery of an airplane were to be weakened by the method indicated by Senator Overman it would prob ably be discovered in the course of the rigorous ex amination and tests to which it is subjected be fore It Is sent from the factory. Still, they admit that a machine so damaged might possibly slip through without discovery. But they do not be lieve that, up to the present time, any such damaged machine has been sent to an American flying field. TU0/?LAff£iS And as for the possibility of a German agent doing any "monkey business" with an airplane after It Is received by a flying field, they scoff •without mercy at the mere suggestion. They do not deny the possibility of spies being present on any or all the flying fields but they do not be lieve that the most astute and malignant German agent could "put anything over" in the hangars which house their steeds of the air. In charge of each hangar is an officer whose dut" it is to know all about each machine in it,___ what happens to each one, where It is at any mo ment, and what its condition is whenever it is in the hnr ar. Three mechanics are detailed to each macnJne to keep Jt in order and groomed for use whenever it may be needed. The flying men are confident that no sabotage could be suc cessfully attempted under these conditions except by means of an organization so large and so unlikely in flying field forces that Its possibility is not worth considering. In addition, no man ever takes a plane up from a flying field without himself first carefully inspecting Its machinery. The aviators are so confident that the fault does not lie in the planes that when they are discuss ing the cause of accidents tliey do not even men tion the planes or their machinery, unless they are questioned by an outsider. They confine their discussions to the human factor involved and speculate upon why his nerves or his muscle, his heart or his brain, failed him at some crucial moment. The percentage of losses among student avia tors Is much larger at Canadian than at the American training schools, while the number of fatal accidents at the Canadian field at Fort Worth, Tex., is appalling. That field has suf fered more casaultles than all the other fields to gether in Texas. The aviators of the American fields are all of the opinion that the fatalities there are mainly due to haste and carelessness In training. At the American fields a man must have had from four to nine hours of training in the air with an instructor, the time depending on his quickness In learning control, before he is allowed to take up a machine by himself. A "tail-spin," one of the causes of accidents most commonly cited, is an acrobatic stunt which an aviator must know how to execute with skill and ease. In it he noses his machine downward with Its tail whirling in a circle above him, whije its nose whirls in a similar but smaller circle beneath him, and He, In the pilot's scat, is the pivot of the two gyrations. To the landsman It sounds a heady sort of a combination, and it is likely to prove so to the airman unless he has the knowledge and the skill with which to manage it. To throw his machine in and out of tail spins is a part of his dally practice after he begins the acrobatic training, and in a very little while he acquires sufficient knowledge of what to do and Instinctive control of the machinery to execute tall spins as easily and safely as he could twirl on his toes or turn on his heel if his feet were on Iflolld ground. But he may get Into a tall spin accidentally In his early flights alone and, although he may 'know what la the right thing to do to take the machine out of it, he may lose his head at the crucial moment and fall to do what he ought Every man. woman, or child who has learned to irlde bicycU or drive en automobile to famllla* with that unconscious Influence of the mind over the muscles which causes one who has not yet acquired complete command of a machine to drive straight at the-object which he wishes and lis doing his beat to avoid. The aviator haa a brief time in his training when he suffers from that iaame difficulty and at important moments la prone to give the wrong pressure upon his con trol stick or his elevator. If he does this when 'his machine goes Into a tall spin and his mind does not work quickly enough to recognize his difficulty nad do the right thing, a fatal accident ls very likely to result.

Or he may Intentionally take his machine into one, before he has had the usual Instruction, out of the spirit of adventure, or even the kiddish desire to con vince himself of his daring or exhibit It to his fellow students. But, whatever the cause, It is the opinion of flying field aviators that getting Into a tail spin, purposely or accidentally, without being able to manage It properly, is the cause of a large proportion of fatal accidents at the fly ing fields. The same perverse, unconscious influence of the mind over the muscles which forces the bicycle learner straight toward the object he is trying to avoid Is responsible for tnany of the fatal accidents due to collisions. Even the most expert of flyers may be unable to avert a serious accident when he sees approaching him a plane driven by a cadet who Is doing his level best to keep his machine out of the other's way. How serious and ever present is this danger in jpyling fields Is proved by Capt. Vernon Castle's death. In flying there are certain "blind angles" .In which collisions are possible through no fault of the driver of either plane. The sections of space covered by the wings of his ship are invisible to the pilot, and If such a section coincides with the space concealed from the eyes of another pilot approaching from below or at one side, a sudden crash Is likely to be the first that either knows of the other plane. This "blind angle" may be the cause of an occasional serious acci dent, but aviators do not think that such collisions are of frequent occurrence. Engine trouble causes many unimportant acd dents, but, aviators say, should never offer any serious difficulty to a man who has learned how to manage his plane, if he is In a region where It Is possible for him to come down safely. And for engine trouble there are as many posslbl«^aB$ legitimate causes as there are reasons for an automobile to balk. In a few cases a broken propeller has caused a pilot to make a forced landing, with injury to Ma plane, but, up to the present time, never with serious result to himself. The accompanying pic ture shows what happened to a pilot when his propeller weakened, cracked and broke over the grounds of a high school in the environs of Hous ton, Tex. He brought his ship down with some damage to It, but none to himself, and greatly to' the delight of the inhabitants of the region. Various causes may result in the breaking of the propeller. It may have been Injured in some previous nose dive to the ground or a bird may have got entangled In its blades. Cadets are for bidden to chase birds because of the possibility of such a result and the sure smashing of the propeller. Nevertheless, they do it sometimes, when the instinct of the chase is strong In their blood. And It would be quite possible for a bird to fly against his propeller,- to the undoing of both bird and propeller, and the pilot to be Ignorant of what had happened. The men who by hard work and steady prac tice have earned the right to the title of "bird men" believe that with both students and skilled aviators one cause of fatal accidents Is the fail ure of the nervous system to respond Immediately and accurately to the command of the brain. Anything which causes nervous fatigue may bring about that physical state—dissipation, nerve strain, physical weariness, lack of sleep. The flyer must be so alert, his grasp upon every situ ation which may confront him so Instant, and his action to meet and control It so prompt that the fraction of a second in the movement of his hand upon the controls of his machine may mean the difference between life and death. And anything which slows by ever ao little the action of the brain In an emergency, or. the flash ing of Its commands along the nerves, or the In stant obedience of the motor nerves may send him crashing to the earth. The cadets before they have become what they call "instinctive flyers" are especially liable to this danger, al though even those who are skilled in the air are not free from its menace. Blrdmen who an skilled In one, or another, or several forms of athletics aay that In nothing else have they felt ao much the necessity of this Instant and com plete response of the nerves to the demand upon them.

In one of the Texas fields recently a lieutenant with a reputation as a skilled and careful aviator fell from a considerable height and was killed instantly. His nearest friends were unani mous in the belief that his fall was due to the fact that he had not been getting enough sleep. For a week he had been giving instruc tion in night flying, working ail night, and had not been ible to sleep well during the 1 running an Careful training and plenty of practice soon bring the student aviator to the point where flying becomes as In stinctive with him, in the movement of hand and foot upon the controls of his ma chine, as the action of his body in walking. For him living becomes as safe as automobile is for the skilled motorist so far as the machine and his control of It and the medium through which or upon moves are concerned. But the unreliability of the human mechanism must still be reckoned with, and that unreliability seems to be greater In the air than It Is upon the ground. It some times results in strange and unexpected happen |ngS. Once in a while a man in the best of health and the pink of condition, who has passed with high success every one of the severe tests to which aviation candidates are subjected, who has never fainted before in his life, will faint while he is In the air. One recent fatal accident at a Texas field is supposed to have been due to that cause. One pilot fainted and the plane fell to the earth, but neither he nor the student with him was hurt except for a few scratches and cuts. He said that he did not know why he fainted. All that he knew was that he suddenly lost con sciousness, and did not regain it until he was being hauled out of the wrecked airplane. He had never fainted before in his life. Neither had another young fellow, to whom everything suddenly became a blank as his ma chine was sailing away through the blue. It was still sailing along easily when presently he came to himself again with the feeling that something had happened to him. Looking down, he could see that he had covered a considerable distance since the moment when he had lost consciousness. He does not know why he fainted any more than he knows why he did not spin downward to prob able death during those blank moments. A British surgeon attached to the relay naval air service, Dr. H. Graeme Anderson, who has had extensive experience at British flying stations, has recently written some Interesting conclusions concerning these somewhat obscure causes of iairplane accidents at training schools. In the opinion of Doctor Anderson, based upon study and comparison of the statements made to him In such cases by a hundred student flyers, there is a brain fatigue not due to previous men tal or physical strain that may yet cause serious accidents. He thinks it is induced by the Impact of overwhelming sensations upon the mind of the pupil alter he is in the air. The flying pupil who Is overcome by this form of fatigue, says Anderson, "reaches- the stage where he has the power neither to reason, decide, nor act. A state of mental inertia supervenes. This is due to repeated stimuli received by his brain tn rapid succession In his flight. He feels alone a suc cession of errors occurs in the air he feels he cannot manage to control the airplane fear does not seize him, but the enormity of the whole thing appalls him *he feels helpless, and a "tate of brain fatigue occurs In which he, in a stupor, awaits events and takes little part in the air plane's control." This form of brain fatigue would seem to be largely a result of personal temperament Doctor Anderson thinks It responsible for "a fair pro portion of accidents" among students In the early stages of flying, and he adds that student avia tors who have suffered from it. If they escape injury, are likely to give up flying. There are many, many of the unimportant ac cidents, of which nobody takes heed. But of fatal accidents, notwithstanding the concern over them manifest In some parts of the country, the percentage Is no greater than should be expected, Is less than In the flying schools of some other countries, and is not higher than it Is In almost any extra-hazardous occupation. And when It Is remembered that this latter comparison brings together figures representing men In the training stage with those of skilled workers, It is evident both that flying is a safer game than It has the credit of being, and that It will be a good plan for the country to guard against hxatarla owm tte tytplittea that do occur.

SYSTEMATIC SAVING URGED People Requested to Pledge by June 28 to Invest In War Savings and Thrift Stamps, or Other Government Securities. Washington, D. C.—To save mate rials and labor for necessary war pur poses, President Wilson appealed to Americans "to buy only those things which are essential to the individual health and efficiency," and to volun teer on or before June 28, National Thrift day, to invest systematically in War Savings and Thrift Stamps, or Mother government securities. "This war Is one of nations—not of armies," said the president, "and all of our 100.000.000 people must be economically and industrially adjusted to war conditions if this nation is to play its full part in the conflict Pledge Is Sought. "The problem before us Is not pri marily a financial problem, but rather a problem of Increased production of war essentials and the saving of the materials and the labor necessary for the support and equipment of our army and navy. Thoughtless expendi ture of money for nonessentials uses up the labor of men, the products of the farm, mines, and factories, and overburdens transportation, all of which must be used to the utmost and at their best for war purposes. "The great results which we seek can be obtained only by the participa tion of young and old In a national thrift movement. I therefore urge that our people everywhere pledge themselves, as suggested by the secre tary of the treasury, to the practice of thrift to serve the government to their utmost In Increasing production in all fields necessary to the winning of the war to conserve food and fuel and useful materials of every kind to devote their labor only to the most necessary tasks, and to buy only those things which are essential to Individ ual health and efficiency. -"Buy More U.

"I appeal to ull who now own either Liberty bonds or War Saving stamps to continue to practice economy and thrift and to appeal to all who do not own government securities to do like wise and purchase them to the extent of their means. The man who buys government securities transfers the purchasing power of his raonejTto the United States government until after this war, and to that same degree does not buy In competition with the gov ernment.

John 13:1-35. I'ltlilAld' TOPIC—Jeeue ples.-Mark 14:12-28. II. The Last Passover (w. 12-25). 1. The preparation (vv. 12-16). In reply to the disciples' Inquiry as to where they should prepare the Passover for him, Jesus told them to go Into the city where they would meet a man bearing a pitcher of wa ter, whom they should follow. In the house to which they were thus led would be found a guest chamber —a large upper room—where they could make ready the Passover. This Is an example of Christ's superhuman knowledge. He not only knew that the disciples would meet this man, but he knew that Judaa had bar gained for his betrayal. 2. The betrayal announced (Tt. JLT»'' 21). The betrayal was to be by one of the disciples who was eating with Jesus. This betrayal had been pre dicted, though such prediction did not interfere with the free act of Judaa In the betrayal. It was because of this act of treachery being freely committed by Judas that Jesus pro nounced upon him the awful doom— "Good were It for that man if he had never been born." 3. The bread and the cop instituted (TV. 22-25). III. The Disciple* Cowardice Fore told (vv. 26-31). In spite of their cowardly tuT-nlng from the Saviour, he assures them that after his resurrection he would go before them Into Galilee. Peter protested against such act of disloy alty by the disciples, and assured the Lord that though all the rest should forsake him, yet he would not. The Lord showed film how little he knew even of his own best resolve, telling him that on thnt very night he would deny him thrice. All the disciples said the same tiling. IV. The Agony In Getheemane (vv. 83-42). The clear vision of the coming anguish of the Cross, accentuated by the utter failure of the disciples to understand or believe, brought upon him an indescribable anguish of soil, so he took Peter, James, and John and went apart to pray. The cup of agony was not mere death, but the sacrificial death for sin, under the weight of the world's guilt. 1. The first prayer (vv. 85-38). i Notwithstanding the darkness of the hour, he prayed In faith accom panied with a willingness to obey. When he came and found the three sleeping Instead of prnylng, he com manded them to watch and pray so as to be fortified against temptation. V. The Betrayal and Arreat of Jesus (vv. 43-52). 1. The sign to the mob (w. 43-47). With the basest of hypocrisy Judas pointed out Jesus to the mob by a •kiss, the sign of love. 2. Jesus forsaken by all (w. 48-52). At the sight of the Master's be trayal and arrest, one of his disci ples attempted to defend him by. re sorting to the sword but seeing that Jesus made no attempt at resistance, they all fled. Their courage failed them in the hour of trial. How little man knows of his weaknesses until the crucial hour. VI. Jesus Before the Sanhedrln (vv 63£5). 1. Contradictory testimony of false witnesses (w. 53-59). fe High Priest's Questlo&M V 65). (1) "What is it that these witness against thee?" To this Jesus was silent, showing that no evidence had yet been given worthy of answer. (2) "Art thou the Christ?" To this he definitely replied: "I am" and quotes a Scripture passage which they recognize as referring to the Messiah. This claim they answer with buffeting and the most shame ful treatment. VII. Peter Denlea Lord (w. 06-72). Though Peter lovea Jesus, yet la the hour of supreme trial he falla. Grievous as his sin Is, It Is not Ilka that of Jndas. His failure was due to 1. Boasting self-defense (vv. 29-81). 2. Lack of watchfulness (v. 87). 8. Neglect of prayer (v. 38). 4. Service In the energy of the flesh (v. 47). 6. Following Jesus afar off (v. S4). 6. Seek comfort among the Lord** enemies (v. 67 compart Luke 22:55). 7. Open denial. (vv. 68-72).
