oming up, ex-cept the little he can get by ankle-motion. A closeexamination will show^ that, whereas the crank is longer,the man has a proportionally less number of degreesthrough which he can drive it. Time, as well as force,enters into the problem of driving a bicycle; the timeis equal to the number of degrees the crank travelsthrough; here a man only has one-third, or less, ofthe circle, through which he has any power to turn thewheel. It is of no advantage to have one-third longerleverage if you have one-third, or over, less time, ornumber of degrees, to transmit power. The enormousmistake of this inventor consists in the fact that itwould actually be better if he transmitted his powerthrough the arc of short, rather than that of the long,leverage. If you do not increase your vertical ampli-tude, or resultant, depend upon it you cannot increaseyour power unless, at least, you push through a com-parable number of degrees at better advantage. 256 CYCLING ART, ENERGY, AND LOCOMOTION.

A STRONG BREED OF PUPS. 257 To all whom it may concern : Be it known that I, F. H. C. Mey, of Buffalo, inthe county of Erie and State of New York, have in-vented a new and improved Dog-Power Vehicle. This invention relates to vehicles which move fromplace to place on roads, pavements, etc., and consists inan improved construction thereof. A is the driving-wheel, which in this instance is inthe front of a vehicle having three wheels, but may bein the rear, if preferred, or in any other location. The animals being placed in this tread-rim, asrepresented in Fig. 2, and caused to work, will impartmotion to the wheel and to the vehicle, as will beclearly understood. Having thus described my invention, I claim as new, and desire to secure by LettersPatent,— The combination of wheel ABC with a pair ofwheels and body to form the running-gear of a vehicle,in the manner shown and described. ^F. H. C. Mey. The claim could have been greatly improved by in-cluding the whip D and female E in the
