S'elocity as that the chain made one revolution in five 

 minutes. On these data, let me afk what would be 

 its force as a moving power? 



Say, the half of five minutes, is two minutes and a 

 half. In two minutes and a half there are 150 se- 

 conds ; and consequently the fuUhuckets, on one side, 

 would, at all times, exceed the empty ones on the op- 

 posite side by 150 pounds ; of course, even this small 

 stream would act with a pov/er equal to 150 pounds 

 upon any machinery to which it was applied. But an 

 ordinary mill stream, instead of one pound in a second, 

 discharges nearly a hundred pounds weight of water 

 in the same time. With such a stream, the power of 

 a machine on this construction would be equal to 

 15,000 pounds, — a power that no strength of machi- 

 nery could withstand. Where such a stream there- 

 fore could be commanded, with such a fall, it might be 

 subdivided into a great many smaller ones, each of 

 -which would have power sufficient to turn a mill. 

 If the height were a Imndred feet, the power of the 

 same stream would be doubled ; and so on for any 

 greater height. 



Nothing can be more simple than the applying 

 this power, so obtained, to the moving of machinery. 

 It is only to place a vertical wheel, corresponding to 

 the water wheel of an ordinary mill, at one side of 

 this moveable chain, having upon it, instead of flat 

 float boards, firm pins, or teeth, fixed in it at regular 

 distances, to be laid hold of by others corresponding to 

 them, made by the pins that connect the links of (he 

 chain j so that, in proportion as the chain moves, the
