Owing to the nation-wide insistence upon Cypress, "The Wood Eternal,' for all uses that invite decay, (as well as for artistic uses in interiors), it became necessary to devise safeguards for lumberconsumers who have had no reason to become skilled in identifying different woods or in judging their gradations or adaptabilities. The one way for you to be sure that the Cypress you get was grown in a region near enough to the coast to possess the MAXIMUM of decayresisting quality is to refuse all but genuine "TIDE-WATER" CYPRESS-and the-only way to know that you're getting Tide-water Cypress is to insist (and keep on insisting) upon SEEING WITH YOUR OWN EYES the REGISTERED TRADE-MARK of the Southern Cypress Mfrs.

Half a mile of rutted and shell-scarred road a terrible handicap for anything on wheels in peace time, and now an almost certain path to death. But not one of the six motorcycle despatch riders hesitated. The message must go, and they had volunteered for the job. "No. 1," called the officer. No. 1 bent low over his handle-bars and was off. For a furlong he went steadily. Then the watchers saw him crumple up and go into a ditch. The dust of the shell had not subsided before No. 2 was off. They got him in a scant hundred yards. was off to a racing start before a word could be spoken. "He's making close to sixty," muttered a mechanic, absorbed in the most thrilling race he would ever see. The watchers saw the rider pass the quarter mark safely; groaned as the machine hit a shell-hole and sailed through the air in a leap it seemed no fabric could air in a leap it seemed no fabric could survive; cheered frantically as the rider hit the road again safely and sped on; and then drew long, sobbing breaths of relief and reaction as the man disappeared behind the friendly shelter of the wooded hills at the end of the stretch. What that rider did "Somewhere in France," as told by one who saw it, is what every member of his corps stands ready to do; and with its remembrance tests such as that shown in the photograph below seem easy. The spring-board represents the take-off at the edge of a shell-hole or gully. The machine is tuned to a fifty-mile-anhour clip, and when it leaves the board it sails rapidly through the air. Training for the Motorcycle Corps He is taking a leap of thirty-six feet through the air on a motor- This is one of the tests for despatch riders. The camera caught J. W. Terhune, of Hackensack, N. J., in midair as he was trying out the spring-board. He made a record record jump of thirty-six feet, and came down right side up. If he hadn't, the soft sand at the seashore where the test was made would have treated him more kindly than would the hard packed dirt of a French road. Recently Terhune's record was broken by Private H. G. Gates, of the United States Army Detachment Training School at Richmond, Va. Private Gates' jump measured fifty-nine feet three inches. |
