latter also has a median splice, wliicli may be separated to allow one of 

 its halves to fold against the side of its other when the machine is to be 

 made very narrow for hauling through gates, &c. For this purpose 

 also the extension-arms at the sides and spliced to either of the ends of 

 the diagonal bars, or the cross-bar may be turned forward to lie paral- 

 lel to the diagonal pieces, and the barrel should be lowered. The rear 

 tripod-legs close also, for they are joined to the frame by hinges. The 

 wheels should not be set too close together, else the high tripod may tip 

 over in driving upon the row ridges or other obstacles. The shafts are 

 hinged to arms upon the front leg, and this with the wheel can turn 

 easil}^ at the top upon the pivot which is loose in the arch, but has a 

 collar clamped tight to the frame. The front leg of the tripod has foot- 

 pins by which to ascend to the pulley at the top. The windlass is of 

 iron with a cylinder about 1^ inches in diameter and a crank 18 inches 

 long. This has a stop-button on the front tripod-leg, which also sup- 

 ports the windlass. Two small two-wheeled pulleys are used with a 

 rope three-fourths of an inch thick. Its end is provided with a pair of 

 barrel-hooks, which clutch the chimbs. A full-sized barrel of poisoned 

 water is raised by one hand, but it is rather hard straining unless gears 

 be added to give better leverage. A small half- barrel, wine or beer keg 

 that will hold from 10 to 20 gallons is much preferable. With the bar- 

 rel 10 to 12 feet high pressure enough to sprinkle ordinary cotton from 

 beneath is secured, and with my cyclone nozzles it applies 10 to 15 gal- 

 lons to the acre. The machine does not thus give as much pressure as 

 would a force-pump, and hence the spray is much coarser. When de- 

 sired, a small force-pump is secured to the frame and may be worked 

 with one hand or a treadle, or a rachet lever playing upon the spokes or 

 upon lugs attached to the fellies or rim of the wheel. If the barrel is not 

 carried low upon the frame, the pump should be attached upside down. 

 The arrangement of the pipes is on essentially the same plan as has 

 already been described. The wheels being far apart and at the three 

 angles of a triangular frame it conforms excellently to all undulations of 

 the ground and has a broad base to support the barrel, which is situ- 

 ated as within the apex of a pyramid. The frame can be made and 

 put together easily. This machine, whether operated automatically or 

 by a pump, is a practical device, and where wagon wheels are used it 

 will not prove high priced. 



^' The Schanclc SprinUer. — This sprinkler, invented by Mr. Lafayette 

 S. Schanck, of Marlborough, N. J. (patent No. 215683, May 20, 1869), 

 consists of the barrel with a stirring apparatus and with two or more 

 pipes connected with the bottom of the barrel, each having a finely- 

 perforated nozzle. The whole apparatus is placed on a cart. 



^' The Taylor Sprinkler. — The sprinkling apparatus of the Taylor 

 dusting and sprinkling machine should be mentioned in this connec- 

 tion. Plate LYI, Fig. 4, gives a representation of this machine, but 

 with the dusting arrangement detached. Leaving out those parts that
