INJURIOUS INSECTS. 
15 
Where shade trees in town are being attacked 
it would seem best for the town authorities to take 
the matter in charge and appoint some capable 
person to spray all of the trees in the place. 
Otherwise there will be a great many who cannot 
be induced to spray their trees and the pest will be 
continued from year to year. 
While speaking of the remedies for the Leaf- 
rollers, I should do wrong not to mention the valu¬ 
able services of the toads. 
One of the most interesting sights that came 
under my observation in Greeley last summer was 
the large number of well-fed toads that hopped 
lazily about on the walks under the trees from 
morning until night, watching for Leaf-rollers that 
were dropping on every side. The rollers were 
usually snapped in by the toads even before they 
could reach the ground. As many as fifty of these 
toads were counted under a single tree, and it 
was not uncommon for people to take the middle 
of the street to avoid the toads along the walks. 
Toads seldom do harm and feed almost entirely 
upon insects and should be carefully protected, as 
they are decidedly beneficial.
