The pressure of tlie pumps will, in every instance, swell a poor hose to double its diameter. It is therefore necessary in the start to purchase a good quality, and the most desirable size to use is the half- inch four-ply rubber hose. The sections should not be less than fifty feet, as with this length the operator can pass around the tree and thoroughly spray every portion before leaving it. SPRAY TANKS. Fig. 60. A fifty-gallon barrel with a square piece (eight by ten inches) sawed out of the head, beveled so as to prevent it dropping in, and fixed with a pair of brass hinges, makes a good tank, where only one line of hose is used. The pump, when practicable, should be bolted to the head of the barrel. With other styles of pumps a nipple near the bottom should be placed, to which the suction hose can be attached. This outfit can be carried upon a sled, drawn by one horse. But where con- siderable spraying has to be done, a tank holding from two hundred to two hundred and fifty gallons should be constructed and mounted upon a farm wagon having broad tires. The material should be well seasoned, one and one half inches thick. All the joints should be Avater-stopped, ('. c, grooved, into which is fitted a long slat. This will prevent leakage from strain or shrinkage. The tank should be bolted together with long iron bands; one end of each should be provided with screw and nut, so that it can be tightened. Upon the top and to one end should be a hopper, with the sides beveled, and eight inches high, and wide enough to admit the entrance of a man if necessary. Int
