A piece of pine plank, D, is suspended from the cross-girth of a frame, E, by an iron bolt, F, furnished at its lowered end with a large head, G, and a washer, and secured by a key, H, at the upper end, admitting of an easy circular motion of the body around the bolt This motion is coincident with that of a swivel on the piston-rod, I. The rudder, or vane, will necessarily throw the wheel, at all times, into the wind. The axle, A, is suspended from the body by two straps of iron, through which it passes at L, L, where it is cylindrical, allowing free motion. The sketch oh Plate I, was drawn from recollection without regard to perspective and proportion, but will perhaps illustrate the subject sufficiently.

A breeze which merely agitates the leaves of the trees will set the machinery in operation. A reservoir of some six or eight hogsheads was kept nearly filled, and when, in windy weather, a surplus of water was raised, it was returned to the well by a waste pipe, M. In the hands of an ingenious mechanic it might, no doubt, be greatly improved. Iron, in some of its parts, might be substituted for wood.

A well, suitably located, will furnish water enough for an ordinary garden, and without labor, by aid of this mill. How much it would improve our flowers, fruits and esculent vegetables, cannot be estimated, but would surely effect a revolution in our present modes of gardening here in the West, where we suffer much every season from drouth. Public tanks, inns, tanneries, and thousands of prairie farms, require its aid. Downs & Co., or some other active firm, would render the community essential service if they would manufacture a supply of these mills and adapt them to some of their improved pumps.

In all this, gentle reader, there is no Quixotism. Its feasibility has been amply tested. We may, however, trespass on the peculiar province of the Don, and, like him, get our heads bruised when we give play to our imaginations on this subject. We will venture on the movement.

Attempts are everywhere making to ornament and improve country and suburban residences. Few localities are naturally furnished with the means of supplying a jet d eau, yet it is one of the most important ornamental additions art can supply to such places. One of moderate size can be constructed at any point where a well with permanent and abundant springs can be obtained within twenty-eight feet of the surface of the ground. Practically, beyond that depth, this mill will not raise water with much success. It is obvious that the same wind operating on one mill, and raising a given quantity of water twenty-eight feet, would, by acting on a second mill, raise the same water an additional twenty-eight feet.

Suppose an architect should sketch a barn, or other out-building, with two spires or towers of suitable height and dimensions, giving them an air of and beauty. The outline I have attempted to supply in Plate II, but not the fini.

PLATE II.

A, represents a well, either under or contiguous to one of the spires. B, first windmill, working pump, C, placed on the center of a wooden cistern, D, of thirty or forty hogsheads capacity, whose bottom is perforated with pump stem, E, E, extending down into the water in the well. F, second wind-mill, working pump, G, and filling reservoir, H, of similar capacity, from reservoir, D, through a tube I, I. J, J, conducting tube. O, the hydropathic mermaid, cascading dolphin, or any other monster fancy may create. L, stop-cock to let the water on the jet N, stop -cock to let the water directly into the basin, and not through the jet. The waste water is finally discharged into the well, A, by tube, M. The pressure on the tube, J, J, might be too heavy while the water was not discharging at the basin; stop-cock P would relieve it The waste water from cistern, H, when full, may be discharged through tube R, into conducting tube, J, J.

By these arrangements, sixty or eighty hogsheads of water would always be at command, and at an elevation at which it might be conducted over the dwelling house, lawn, garden, trees, etc. During calm weather it would keep a jet of moderate dimensions in play for several hours, and in windy weather the supply would be constant On the shores of Lake Erie no day passes without furnishing wind enough to keep the reservoirs replenished. In case of fire they would be equal to an ordinary fire engine. Is this Quixotism!
