“ When at rest, or when traveling steadily over even ground, the motor occupies a position in the lower portion of the frame; but when the power is applied the motor moves forward and upward in proportion to the resistance encountered. The seat also rises, but in a lesser degree, and it holds its vertical position by swinging in the standards.
“ The tractive effect, being thus secured by the rising movement of the weight within, enables the wheel to travel over any surface however smooth without slipping and to climb grades which no other machine can overcome.
“ Since by the great diameter of the main wheel the monocycle is useful for traveling through rough country, ordinary obstacles presenting but slight obstruction to its passage, its inventor claims that it will prove of service for military purposes, and also to those who for business or other reasons are compelled to pass through desolate territory. Its inventor has great expectations of the monocycle as a racing machine. Its small width (being in all but thirty-four inches when the auxiliary wheels are retracted) causes it, with the assistance of the rotative movement of the rim, to glide along rapidly, attaining a speed of a mile per minute without being subjected to severe atmospheric resistance.
“ The monocycle differs from other motor-driven vehicles in that it does not draw upon the ground to produce the tractive effect, but, tumbles forward with continuous falling motion, applying new surfaces of the tire to new surfaces of the ground without relying upon the stability of the latter for maintenance of motion. It thus has the distinction of being the only machine which successfully travels on loose sand, and, therefore, the first practical substitute for the ancient ship of the
