performs the same functions as does the direct current brake. The safeties used on the Gearless Traction Elevators are found on the Geared Traction Elevators. The main difference between the two machines lies in the ability to use on the latter a small high speed motor with gearing, instead of the large, slow speed highly efficient, but more expensive motor of the Gearless Traction Elevator. $22,000,000 IN SCHOOLS Washington, Jan. 1. In round numbers there were 22,000,000 persons enrolled in educational institutions in the United States in 1914, according to the annual report of the United States commissioner of education. Of these, more than 19,000, 000 were in elementary schools, 1, 374,00 in secondary schools, both public and private, and 216,000 in colleges and universities. Close to another 100,000 were in normal schools, preparing to be teachers; 67,000 were in professional schools and the remainder were scattered through other types of institutions. The teachers for this educational army numbered 700,000, of whom 566,000 were in public schools. In point of rapid growth, the public high school still presents the most impressive figures; the enrollment for 1914 is greater by over 84,000 than for the year before. The cost of education for the year, as estimated by the bureau, was $750,000,000. "This amount is a relatively small sum when compared with other items in the public expense," declares the report. "It is less by $300,000,000 than the cost of running the federal government; it is only a little more than three times the estimated cost of admissions to moving-picture theatres in the United States for the same year."

Whereas, It is in deep sorrow and with extreme regret we learn of the death of Brother W. E. Brown, who passed away November 12, 1915; and Whereas, In his death the District Council of the Carpenters' Union has lost a true and loyal brother, an officer of sterling qualities, beloved and respected by all who knew him; therefore, be it Resolved, That Local No. 11 of the International Union of Elevator Constructors of Cincinnati, Ohio, in meeting assembled, extend our most sincere sympathy to his family, relatives and friends. LOCAL NO. 11, I. U. E. C., TRY AGAIN Mountains aren't as big as men. Human will overtowers and overpowers everything on earth. Nature hasn't yet stacked anything too high for ingenuity to knock down. The hardest thing we know is a man's head-he can cut diamonds and ram tunnels with it. In that inexhaustible warehouse, your brain, there's a rule, an implement, a philosophy or a batch of explosives, somewhere among its millions of cells, to deal efficiently with any emergency. History has compiled a partial inventory of its resources-all past talent and genius is a catalogue of your potential abilities—everybody may do what anybody has done. But the experience and experiments of others did not locate the tools you require to handle new ways. There are more undisclosed stunts in your mind than of record. Progress can't dig them out of hiding fast enough to exhaust the reserve stock. School boys answer riddles that the Sphinx couldn't invent, but their grandchildren will, in turn, rattle off facts that now elude Edisons and Remsens. Granted that our voices outreach thunder and that we toast muffins with educated lightning bolts-we are still reading the first few phrases of knowledge. But at least, we have the formula that solves every secret-thought, work, doubt. With the Simplon, the wireless phone, Holland's synthetic shark, radium and aviation, already to our credit, we surely can't be expected to waste patience on people who bungle ordinary chores. If you aren't making a decent living in these flying times, you haven't made a decent effort. What's possible is half done-it's just the half-done things that are impossible. Wits sharpen upon disappointment. If you haven't a few bruises you haven't been fighting. Temporary failure is a phrase of experiment. The incandescent lamp didn't glow at the first trial, nor go at the thousandth. Even a desert will yield to a fertilizer of persistence and intelligence. All fixed obstacles must eventually succumb to thought. The obstacle remains the same and in the same place, but man and his mind are mobile-he can keep altering and improving his tactics and mount steadily upon the shoulders of previous effort, until he stands where he can strike to win. There's more than enough opportunity-but most folks expect an door. Or they turn the knob and turn away, because the first motion they have at hand won't turn the latch. |
