being required by two men with force pump, tank and ladders to treat one 

 tree. The poison necessary for each spraying was worth about 6c. It' will 

 thus be seen that the cost for each tree would be between 36c and 50c, vary- 

 ing with the price of labor. In New Brunswick, N. J., the trees were 

 sprayed at a contract price of $1 for the season, the understanding being 

 that they were to receive three treatments if necessary. The contractor 

 prepared the outfit, furnished the material, did the spraying at the price 

 mentioned and had a neat margin remaining. 



The cost of spraying elms in Albany in 1898, aside from wear and tear 

 of the apparatus, was about i 5c a tree for each spraying. This average was 

 based on one or two days work and probably would not hold for the season. 

 It is very likely that it would have paid to give each tree a little more time, 

 which would have brought the average cost up somewhat. The elms of 

 Albany range from 20 to about 70 feet in hight, though most of them are 

 over 50. 



The average cost of one spraying in Albany in 1900 was about 22c a 

 tree. The spraying was done with apparatus to be described later, and 

 under civil service regulations, which require men to work but eight hours a 

 day. Two power spraying outfits under one foreman's direction constituted 

 the force. It would be possible in private work to reduce the force some- 

 what and have one man serve both as motorman and driver. A little more 

 selection could also be exercised and possibly more efficient men secured 

 than can usually be obtained for such work under civil service regulations. 



Mr H. \V. Gordinier of Troy found that in contract work in the village 

 of Lansingburg, where he sprayed all the trees, the average cost a tree for 

 each spraying was 23c. This figure, however, was raised considerably in his 

 work in Troy where the trees were sprayed at the expense of private par- 

 ties and there was necessarily much running hither and thither ; under these 

 conditions it ranged from 50c to 60c a tree, the cost depending on the size 

 and the number in one locality. Large maples have been sprayed at a cost 

 of only 17^ cents per application, as stated below. 



The saving in cost shown by the above figures, not to mention the
