Page 16 - ... to which the valve has been adjusted, but is superior to it, by which it is enabled to overpower the resistance of the weight t, and it carries the valve up with it, and closes the orifice r. This is no sooner done than the water is constrained to become stationary again, by which the momentum is lost, and the valve and weight once more become superior, and fall, thus...
Page 16 - ... connected with the side of the reservoir, and terminating by an orifice r, in which a conical or other valve, s, is placed so as to be capable of effectually closing the pipe when such valve is drawn upwards: t, is an adjustable weight fixed on to the spindle of the valve...
Page 631 - Where the conduit pipes are of great length, say upwards of 1000 feet, it is found advantageous to begin, at the reservoir or cistern, with pipes of a diameter somewhat greater than those which deliver the water to the quills, because the water, in a pipe of uniform diameter of so great a length, is found to lose much of its strength, and become what is technically called sleepy : while the different sizes quicken it, and redouble its force.
Page 112 - ... its direct rays at a low angle, and, consequently, very obliquely to the glass. At those periods most of the rays of light and heat were obstructed by the position of the glass and heavy rafters, so that a considerable portion of time was lost both...

Page 701 - This would both be inconsistent with their breadth and would render them too prominent and artificial. They should not be carried higher than the point at which they can be well supported and backed with a broad mass of earth and vegetation. Additional height may sometimes be given, if desired, by excavating...

Page 696 - William for them) affords us but few materials to work with. Plants, ground, and water, are her only productions; and, though both the forms and arrangements of these may be varied to an incredible degree, yet have they but few striking varieties, the rest being of the nature of " changes rung upon bells," which, though in reality different, still produce the same uniform kind of jingling ; the variation being too minute to be easily perceived," " ART must therefore supply the scantiness of Nature,'
