Three ounces copper carbonate — One quart ammonia, thirty gallons 



water. 



Dissolve the copper carbonate in the ammonia, and add to the 

 desired amount of water. In some instances where the ammonia is 

 very strong — 26° Baume — the foliage is scorched, unle&s the mix- 

 ture is more dilute. With 26° ammonia dilute to thirty-five gallons. 



In preparing either of these mixtures, it is well to make the stock 

 solution the day before applying, and to make a considerable quan- 

 tity — merely observing the proportions suggested. 



The ingredients of the first solution may be obtained at any local 

 drug store. Carbonate of copper, and ammonia in bulk may be 

 obtained of Weeks & Potter, Boston, Eimer & Amend, New York, 

 W. S. Powell & Co., Baltimore, Md. 



Copper carbonate will cost about fifty cents per pound. Ammonia 

 by the carboy, of eighty pounds, costs nine cents per pound. 

 Sulphate of copper costs about ten cents per pound. 



APPARATUS. 



Good force pumps with suitable spraying noz/,les are now obtain- 

 able at very reasonable prices. We have been very well pleased 

 with the '"Perfection," manufactured by the Field Force Pump Com- 

 pany, of Lockport, N. Y. This pump has a discharge pipe return- 

 ing to the bottom of the barrel, thus keeping the mixture agitated. 

 The pump with brass cylinder and plunger costs S12.00. 



Good pumps may also be obtained of the Gould Manufacturing 

 Company, Seneca Falls, N. Y. 



On general principles, the "Climax" nozzle manufactured by the 

 Nixon Nozzle & Machine Company, Dayton, Ohio, is the best. 

 That i3, the spray is more finely divided, than is the case with some 

 others ; but the nozzle is so small, too much time is consumed at 

 each tree. 



When well made, the "Graduating Spray" nozzle which comes 

 with the "Perfection" outfit is very satisfactory. We find that 

 nozzels of this description as obtained from difl^erent dealers, are 

 not uniformly good. 



In applying Paris green, it is important that the spray be finely 

 divided, but with the copper solutions, it is doubtful if the finer 

 spray, and the saving in the quantity of material, will compensate 

 for the longer time required in using the Climax nozzle. 



Under no circumstances is it advisable to purchase a pump with 

 iron cylinder and plunger. The iron will quickly rust, and unless 

 very carefully handled, the pump will be ruined the first year.
