...craned their heads forward to watch the technique. The surgeon grasped hold of the child's crippled leg with his powerful fingers, flexed the knee, rotated the thigh, brought it up and then down with a motion as slow and tremendous as that of a caterpillar tractor. There was a snapping of adhesions, a sickening cracking. The two legs were together, were bandaged into immobility with the hips. The surgeon straightened up. His blue eyes, which had just now been so coldly serious, started to twinkle as the spectators pressed about him with their astonished exclamations, with their compliments...
...used the motor car for almost every other conceivable purpose, leading Detroit automobile makers have now organized a company entitled "Snow Motors Inc.," to put out a machine which will negotiate the deepest snowdrifts at six to eight miles an hour. The new car will consist of a Ford tractor power-plant mounted on two revolving cylinders instead of wheels-something on the order of a steam roller. The machine has already proved its usefulness in deep snow previously unnavigable. One such machine has done the work which formerly required three teams. In Oregon a stage line uses a snow...

Last fall, the Onondaga made its first foreign trip, carrying auto parts to Buenos Aires. Now another ship, the East Indian, is reconditioning at Chester, Diesel engines being installed...
Another unique feature of the design is the tractor propeller. Hitherto, flying boats have been built with the engine mounted behind the pilot and passengers, with the propeller pushing-convenient in docking but offering always the possibility of the engine landing right on top of the personnel. The amphibian with its engine in front avoids this danger. The engine is inverted to improve the pilot's vision and works apparently even better in this position. This expedient, simple as it may appear, has a great military value. In spite of its novel characteristics and multiple function, the new plane...
...prosperity, and reducing the huge War debts. The key to the process lies in communication and transportation. The British apparently expect to open up the continent from north to south by the Cape-to-Cairo Railroad and its feeder lines, while the French have established lines of communication by tractor across the Sahara from Morocco to Timbuctoo in the heart of the continent. No one knows what a thorough exploitation of the continent may mean to the world's trade. Since the War, the development of African Copper properties, such as Tanganyika Copper, has already made its influence felt...
