Sometimes a small lead- en pipe is placed over the other, communi- cating with it in several places, in which is a cock at top, to open upon occasion. 16. When any work is to be performed by a water-wheel moved by the water running under it, and striking the paddles or laddle boards, (fig. 3,) the channel it moves in ought to be something wider _than the hole of the adjutage, an_d”'so close to the floats on every side, as to let little or no water pass; and when past the wheel, to open a little, that the water may spread. It is of no advantage to have a great number of floats or paddles, for those past the perpendicular are resisted‘ by the back water, and those before it are struck obliquely. The greatest effect that such a wheel can perform, in communicating any motion, is when the paddles of the wheel move with § the velocity of the water; in 0 which case, the force upon the paddles is g only, supposing the absolute force of the water against the paddles, when the wheel. stands still, to be 1. So that the utmost mo- tion which the wheel can generate, is but -21‘, of that which the force of the water against the paddles at rest would produce. This is when thewheel is at the best; but, often- times, far less is done. , _. Machines to raise vw+er, when well made, seldom lose less than the computed quan- tity of water to be raised. The best con- trived engine is scarce part better than the worst contrived engine, when they are equal- ly well executed. ’ A man with the best water engine cannot raise above one hogshead of water in a ini- nute, 10 feet high, to work all day. 17. VVhen a weight is to be raised with a given corporeal power, by means of the wheel and axle, so that the weight may re- ceive the greatest motion possible in a given time, the radius of the wheel and axle, and the weight to be raised, ought to be so ad- justed, that the radius of the axle : (fig. 4) may be to the radius ofthe wheel (AB) : : as {g the power (P) : to the weight tism which leads the people to take a deep in- terest in the affairs of their government. Through the attention of the comptroller of public accounts, we have been furnished with the following highly interesting statistics. - It would be both gratifying and useful, would some one or more individuals in each state fur- nish similar tables. There certainly can be no great difliculty in obtaining them, and the labor that they might cost would be more than coin- pensated by th‘e information they would afford.
