The frequent requests for information as to methods of spraying, the apparatus to be used, and the formulae for preparation of insecticides and fungicides is sufficient reason why we present here a condensed statement of directions for this work.

There are now on the market a number of excellent outfits for spraying adapted to all grades of work, and it would be out of the question to specify any particular one to the exclusion of others as meeting all requirements. We are not under anv obligations to any firm for favors even to the extent ot apparatus for experimental work, and hence can name different firms with impartiality. It will be best for each one intending to use such apparatus to get circulars from some of the firms named and select the apparatus that meets the requirements of their particular case as to capacity, cost, etc. The firms we name we believe to be entirely responsible and to manufacture apparatus of excellent quality. The Field Force Pump Co., of Lockport, N. Y., The Nixon Nozzle and Machine Co., Dayton, Ohio, The Gould Manufacturing Co., Seneca Falls, N. Y., all making apparatus of various sizes and furnishing nozzles. The Rumsey Manufacturing Co. make excellent pumps, but do not make nozzles or supply complete outfits to our knowledge. The Lewis and Cowles Co. manufacture apparatus convenient for light work, or where there is a small amount of spraying to be done. Wm. Stahl, Quincy, Ills., makes knapsack pumps and sprays. Thos. Woodason, 2900 D street, Philadelphia, Pa., makes a variety of spraying outfits and powder bellows. For a large orchard the operator should have a good large force pump, capable of throwing a spray to the largest trees, and worked by hand or geared to the wheels of a wagon; the former is in some respects preferable, as it is then possible to regulate the amount given each tree according to the size of the tree, density of foliage, or distance of trees apart. The nozzle should be capable of breaking the liquid into a fine mist not easily clogged and readily cleaned.
