For private grounds of limited extent a fifty-gallon cask or tank with a strong, double-acting force pump' (the working parts of and the valves also of metal), having an air cylinder of one and a half inches or more, and a stroke of five inches or more, attached to the top or side of the barrel, mounted on a cart, with fifty to one hundred feet of half-inch white cotton or rubber hose, ladders and lifting poles of bamboo or quarter- inch gas pipe, will answer well enough for apparatus. The entire outfit, exclusive of the cart, costs between $30 and $40, the pump alone costing from $10 to $15. A barrel pump, satisfactory for general work on small places, can be had for $15, and a bucket pump, which can be used with an ordinary pail or bucket, good to spray bushes and small trees, may be had for from $3 to S7, including rubber hose and nozzle. The most important feature in the apparatus is the nozzle,.
