. Annual report of the Agricultural Experiment Station. Cornell University. Agricultural Experiment Station; Agriculture -- New York (State). t — 41 — kept our bushes clean nearly the whole season, although the young worms were very numerous. Among nozzles suitable for spraying trees, we have used an ordinary hose-pipe and rose, the Gem Graduating Spray, Boss, Crown, Lowell, Magic, Mistic, and Nixon's Nos. 3, 4, and 5. We have also made a test of these under 20 lbs. pressure, having the following points in mind : fineness and evenness of spray, breadth of spray, force, and convenience of manipulation. It seemed to us that for large trees, the Gem, Mistic, and Boss an- swered the requirements best. For small trees, the Nixon's are best. We still need a nozzle for large trees which can be grad- uated without stopping the puriip or lowering the nozzle, and which will not clog. Fig. 8 represents a nozzle which we have made to meet these re- quirements. Like our bush nozzle, the essential feature of this is the compressing of the end of a hose. In ordinary hose the webbing soon becomes loose at the end and causes the spray to split, so that we were obliged to substitute a strong pure rubber tube, to the end of which the hose is attached. This tube, E, is shoved through and cut off a trifle as soon as the end becomes worn. The nozzle is secured to a stick of the re- quired length, by which the operator elevates it toward the.

All things considered, this is the best nozzle for spraying large trees which we have tried. The adjustment of the rubber tube is somewhat perplexing, however, but this can no doubt soon be remedied by the substitution of a rubber thimble made for the purpose. L. H.
