rather than to allow it to depend on the enterprise of private 
individuals, solely because it means the greatest good to the 
greatest number at a minimum expenditure. This imported 
pest is slowly extending its range northward of Albany and 
Troy, and, in some localities where no spraying is done, it is 
this season proving a scourge to both European and American 
elms. 
The cost of spraying shade trees in cities and villages is a very 
important matter; and in a former bulletin! some attempt was 
made to ascertain the expense connected with such operations. 
Figures at that time gave the cost as ranging from about 15c 
to 56c a tree. Some recent estimates have come into my pos- 
session regarding the cost of spraying in Albany and its immedi- 
ate vicinity. Mr H. W. Gordinier states that in Lansingburg 
N. Y., where he had a contract to spray all the trees in the vil- 
lage and where most of the elms are very large, the cost per 
tree for one spraying averaged about 28c, while in Troy, where 
he sprays the trees of private individuals here and there over 
the city and is necessarily obliged to travel considerably to go 
from one lot of trees to another, the cost of spraying ranges 
from 50c to 60c a tree for each spraying. In both cases the 
rather more expensive arsenate of lead was used. Both of these 
figures apply to elmtrees infested with the elm leaf beetle; and, 
as all who have had experience with this pest know, it requires 
very careful and thorough spraying in order to obtain satis- 
factory results. The average cost per tree for spraying in 
Albany in 1901, using 5 pounds of Bowker’s disparene to each 
100 gallons of water, was 22c, and the average number of trees 
sprayed per day by each power spraying outfit was 40. Two 
were operated under one foreman. However, it was found that, 
where the trees were small and of a nearly uniform size, such 
as Norway maples about 30 feet in hight, 180 trees could be 
Sprayed in one day. 
The village of Saratoga Springs undertook to spray its many 
large maple trees, ranging in hight from 20 to 80 feet, in 1900,
