On the basis of this ruling, it was explained, it will be the working policy of the employment service, ex- cept in rases where the closed shop is established, to fill only requests | in which no specification is made for either union or non-union labor. In filling such requests, it was said, an effort will be made to supply equal numbers of each type of labor. | Meanwhile, a showdown as to Whether all Federal construction Work is to be strike-bound over the | issue of use of non-union workmen probably will be precipitated tomor- 10w when the disputed jobs at the City Post Office and Bureau of In- ternal Revenue are expected to get under way.

Nearly everything seems to point to a faster and easier life for the American people and more and more centralization of human activitles. Roosevelt Lauds Report. On receipt of the report President Roosevelt 1ssued the following state- ment: “A review of new inventions and the problems of change which they carry with them is made for the first time by the Federal Government in this comprehensive survey of tech- | nolgogical trends in major indus- ies. For the continuous revision of plans we need continuing surveying agencies. “In our planning for the Nation we must view the general causes and trends that bear on our welfare. | Any specific program may be affected by forces originating outside a par- ticular problem. This report holds out the hope that we can antici- pate some of the affects of major inventions and make plans to meet new situations that will arise as these inventions come into widespread use. | “While it is certain that much of the unemployment scaused by the march of technical advance is ab- sorbed by new occupations born of new industries, it 1s equally true that in the meantime labor may pay a very heavy price through the read- ustment and adaptations necessary on the part of workers whose jobs | are affected by change. Employers | | likewise are deeply affected by swift technological changes producing ob- solescence and displacement of cap- | ital investment “More than jobs | and investment affected by technical change Family, church, community, State |and all industry are subject to its influence. Study and investigation | of technological advances and their social implications constitute one of our most important American plan- ning problems. 1 commend this report for earn- est consideration in solving the great problem of how best to con- serve and develop our vast national resources. A study of this report will | be of heip not only to the public serv- | ants in the legislative, executive and | judicial positions of government, but also to others in private employ, busi- | ness, journalism, agriculture and the | teaching professions.” 1,300,000 Patents Predicted. During the next 30 years, the re- port predicts, there will be at least | 1,300,000 patents issued. Many of | them will be useless, some of them | silly and the majority will have little actual effect on the ways of life of | the American people as a whole. Some, it is entirely probable, mui be along lines now undreamed of and will be revolutionary. The com- | mittee makes its cautious predic- | tions only on the basis of what now | exists in theory or even actual prac- | tice—like the autogyro and televi- | sion—which need only technical im- provement or commercial exploitation lo become vital factors in daily life. Such a development as trans-Atlan- tic air passenger service, for example, seems just on the edge of being | practical, although a generation may elapse before all the difficulties that now stand in its way are overcome. It is highly probable, the report Stresses, that the great developments of the next few decades will be of devices based on principles already known.

The former rests on the su ful development of the so-called *roof hopper”—an aircraft which will go ht up, hover in the air and come straight down at low speed. It now is represented by such forms as the helicopter and autogyro. The for- mer, by the way, was first devised by Leonardo da Vinci Many technical problems remain to are almost by great the growth of | g0 down | | | | | be solved, says the report, “but the | winged horse which can leap into the air, soar or hover in the skies, and drop gently on a constricted landing spot is no chimera—experimentally, at least, it has arrived.” . It would enable the suburban dweller to leave home in the morning and drop down safely a few minutes later ,on his office roof with none of the worries of present day traffic jams. parking, etc. Such aircraft, says the report, “could be housed on roofs or brought to the lower floors on ele- vators. They will have much more freedom of movement than our ent automobiles, since they can in three dimensions instead of It cautions, however, that “while pr vate planes by the ten-thousands probably will be used within another decade, more time doubtless will elapse before they become serious competitors of the private automobile. Types al- ready demons ed which can land on any usable field, fold up like a bectle, and proceed along the ways like an automobile to be housed in the home garage have intriguing possibilities.” Such a- development, it is stressed, will have far-reaching implications in many lines. It will require modif tions in prevalent types of architec- tures. It will extend city limits still further, enable families to go almost anywhere for week-end vacations, and bring about perplexing police prob- Air transport in general, it is pre will become faster, safer, cheaper, cover greater distances and gain in popularity.

The greatest problem of all con- | cerns what shall be broadcast. There must be continuous programs in order to make such a system pay. It will be possible to broadcast stage dramas, dealnig another blow to the already stricken legitimate stage. It probably will be practical to broadcast talking moving pictures and, with the perfection of equipment, there is little reason why one should not enjoy as 200d a presentation in the home as in the neighborhood theater. This might means a terrible blow to this part of the moving picture industry. It probably would not affect the pro- ducers so badly. They still would make the pictures and get their price for them from the broadcasting com- pany or the advertising sponsors. This new development. if it comes. will tend to concentrate life even more in the | home. | standing Teachers May Lose Jobs, Startling are the possible effects on public school systems, as outlined in the report. Television might well scrap a good deal of the present day system of education and even throw the school teacher out of a Job, for it is entirely possible that systematized Jessons might be broadcast to all thé schools in the country by some out- expert. Or perhaps the teacher’s job will be reduced to keep- ing order and operating the school television set. The report stresses, however, that these mav be far-off prospects because education in the | past has been slow in accep’ing me- chanical aids. Farmings’ great ermigma, the report is the mechanical cotton picker, In the near future is seen an effi- cient machine costing about $1.000 which will pick 5,000 pounds of cotton a day.

To- day this is experimentally practical A fairly clear picture of a current event—a foot ball game, for example— can be transmitted into the home on screen large enough so that it can be enjoyed by the whole family. Television can reasonably be antici- pated, perhaps within the next dec- ade, although there are tremendous difficulties in the way. One is the expense.

For economical operation the ma- chine requires large acreages. These necessitate substituting tractors for horses and mules. Cotton farming employs approximately five million horses and mules. About 25,000, | 000 acres in the South are required to supply pasturage, hay and grain for these animals. Great numbers of | them would be eliminated. The land would be thrown out of cultivation. The small cotton farmer would find it impossible to exist. | The millions deprived of a means of livelihood might flock North and | try to replace the workers in northern | industries or the:industries'themselves might move South to take advantage of cheap labor. In either event the social Tepercussions would be enor- mous. The price of cotton would drop enoromusly. This would lead | to an increased demand which, how- | ever, would take up only a little of | the slack. ‘The situation is so potentially full of dynamite that the inventors of | the cotton picker fear to put it on the market until there is some solution of the enigma.
