SOON after water was turned on in a great pipe line in Colorado, trouble began with the joints. There were several hundred of them, all told, twenty-seven being in tunnels through the rock. In some cases, the sand nearby was caught up by the water jets, hydraulic sand blasts were created, and threatened with their cutting power the very integrity of the pipe and rivets.
A NEW form of amusement park device that takes the thrill-seeker aloft in circling swoops has been installed on the "Zone" at the Panama-Pacific International Exposition. The device consists of a steel arm, nearly 250 feet long, which is pivoted at one end, and carries a car for passengers at the other. The whole mechanism revolves on a turntable, so that as the arm rises, the car is carried around in an ascending spiral.

We've been told a hundred times that "Alcoholism is a disease." We've acquiesced in the statement, though but vaguely understanding it, believing all the time probably that in this connection "disease" means moral weakness. Psychology, powerfully bolstering up medical science, now shows us the nature of this disease.

R. MAWSON'S recent voyage into the antarctic world was one of the most remarkable from a scientific standpoint that has ever been made. He did not attempt to reach the pole; his aim was scientific research and he succeeded famously. The scientific importance of his discoveries make him one of the world's greatest explorers.
AN odd compact came to fulfillment recently when Mrs. Alys McKey Bryant, the prominent aviatrice, married Jesse W. Callow, chief engineer of the Pacific Coast Steamship Company. Years before, they had come to the agreement that if, at the expiration of ten years' time both of them were free, they would marry.
ELECTRIC car owners and dealers in the Central Park district of New-York City have banded together and built a co-operative garage. One hundred electric machines have been placed in the new station and six dealers in electrics and accessories have taken show room along the street frontage. As the result, the fortunate ones have reduced storage expenses considerably.
OCEAN travelers who must have a horse-back ride before breakfast, are now accommodated on the Cunard liner Franconia. The gymnasium of that boat is equipped with several trotters, all run by little electric motors which are adjustable to produce any gait from a canter to a wild gallop.

MISS TINY BRODWICK, an eighteen-year-old girl in San Diego, California, recently showed her faith in the safety parachute for aviators invented by her father, Charles Brodwick, by dropping to earth from a flying parachute. The feat occurred before a crowd of visitors at the San Diego Exposition, and the parachute worked in perfect fashion.

When Uncle Sam Was Right, and Europe Was All Wrong
By EDWARD C. CROSSMAN
AMONG the thousand and one things for which the Allies are "enclosing you check and order," to American makers — — are all the telescope rifle sights of our army type the makers thereof can turn out. And in this lies one of the biggest triumphs for the Ordnance Department of our army, after seven years of ill-concealed snickers on the part of European military authorities.

TO thwart the genial trademark pirates of the Spanish main, the governments of the twenty-one republics of the New World are being encouraged by Uncle Sam to put into early practice a form of "team work" new alike to business and statecraft.

EACH year, at Stanford University, there is built an enormous bonfire pile, which is lit on the night of the big football rally and around which the students pledge their support to their team, two days before the big game with the University of California.
A good idea of the size of the pile can be obtained by comparing it to the men standing by it. From the top of the tower to the ground is over fifty feet, while the huge pyre measures over thirty feet at the base. The tower of the pile is an imitation of the Sather Campanile, one of the new buildings of the University of California.

LARGE steel tanks are rapidly replacing the old-time cask on board the modern whale-ship. It was necessary to cool the oil before filling the old style cask because the heated oil damaged them.
AN odd game played with potatoes by horseback riders is a feature of the "Rodeo", a gathering of cowboys in the Southwest. The potato race is played in this way: each one of two teams consists of four horseback riders, each man carrying a long stick with lance-like points.

SCISSORS GRINDING UP TO DATE
THOSE who are inclined to regard the scissors grinder as a dull sort of fellow, who is content to push a cart with a tinkling bell through the streets, may well
contemplate the picture reproduced herewith, of another sort of scissors grinder. He uses his bicycle, riding it until he has work to do, and then supports the rear wheel in the usual way, and uses the machine as a source of power and as his work-bench, too. A simple attachment runs the emery wheel mounted on the handle bar, and the up-to-date grinder may sit at ease and pedal as he does his work.

MAJESTIC harmonies overwhelm the fashionable audience gathered to hear the great composition; the musicians are thrilled by the power of their concerted work; the conductor has forgotten himself in the ecstasy of power he holds over the minds and hearts of those present in the hall. It is a musical triumph.
Over the heads of the musicians stretches a gauze screen, and across this screen play many-colored lights, blending, sweeping onward in overpowering beauty.

THE American public believes in miracles, in the power of sudden invention to stem national disaster. Perhaps it has substantial foundation for its faith—Ericsson's "cheese box on a raft" came in the nick of time to save the Union fleet and keep intact the North's blockade of the Confederacy ports, and our inventors, with submarines, aeroplanes, and torpedo improvements have shown that they can work miracles.
