POWER SPRAYING AND POWER SPRAYERS 
No longer do those entrusted with the 
care of our shade trees and forest pre- 
serves attempt to ignore the fact that spray- 
ing is their most important aid. Nor do 
they attempt to dispute the fact that it is 
better economy to spray and preserve than 
it is to put off and lose what nature has 
required many years to produce. One of 
the worst examples of this neglect is seen 
in the ugly stumps in Cambridge, Mass., 
that once boasted of its magnificent old 
trees. 
Not only has this city lost man)' of its 
beautiful shade trees and been put to the 
expense of cutting them down and remov- 
ing the stumps, but to the cost of replant-

ing the neglected district and cultivating 
the young trees. Not only must scores of 
years elapse before the city can point with 
pride to its trees, but during this period 
the spraying which would have saved the 
original plantations must be resorted to to 
preserve the new ones. 
The question of protecting forest trees is 
a very important one and is being over- 
looked almost entirely by farmers and in- 
dividual owners who have shade trees, al- 
though in some localities they realize the 
necessity of spraying these trees in order 
to keep them in a healthy condition. In 
many instances where the forest trees are 
sprayed a gasoline power spraying outfit is 
used, and instead of the ordinary spraying 
nozzle, which makes a fine mist spray in 
the form of a cone shape, they use a 
straight nozzle, which throws a stream 40 
or 50 feet in height. For small shade and 
ornamental trees, however, the smaller out- 
fits have been used. 
Opinion among sprayers is divided as to 
the relative merits of the “mist spray” and 
the “solid stream” method. The “mist 
spray” is widely used in fruit tree work, 
and for many years this was the only 
method. Unquestionably, good results may 
be secured by it in any spraying, but in 
shade trees or forest work, where tall trees 
are sprayed, it is sometimes considered too
