the presence of the pest is not discovered till much damage is done. 
All broken limbs should be cut off at least a foot below the fracture 
and burned, and this would help to check the insect. 
It is a very serious subject and should interest everyone, for it is 
quite certain that the Leopard Moth has come to stay, and will, I fear, 
be more difficult to eradicate than the Gypsy Moth, as it is a general 
feeder.* Formerly it was a comparatively easy matter to grow fruits 
for market, but now, with tenfold demands for them, and the terrible 
increase of imported pests, it is difficult for a farmer to realize a fair 
remuneration. Success can only be obtained by eternal vigilance and 
unremitting care, and withal how many failures occur. Itis most sin- 
cerely to be hoped that everyone who has the real welfare of our coun- 
try at heart will see the importance of using every means to check the 
ravages of the moth before it spreads destruction to all our shade and 
fruit trees and those of our forests.

HOW FAR DO BEES FLY? 
By FRANK BENTON. 
Items under the above heading have been going the rounds of the 
papers, and the opinions expressed differ greatly, some claiming ‘“ that 
bees will not go farther than two or three miles,” while others think 
the distance is greater, one even naming 12 miles as the limit. After 
mentioning the fact that the bee makes 190 wing-strokes in a second, 
one of the items widely copied says that “scientists claim that 190 
strokes per second would propel the bee forward at the rate of a mile 
per minute,” and then that “conservative writers admit the bee’s— 
velocity to be at the rate of at least 30 miles per hour.” The same 
writer then goes on to say: ‘ Basing our calculations on the latter 
*The Gypsy Moth is also a very general feeder, but, being a leaf-feeder, is easy to 
reach with insecticides.—EDs.
