the presence of the pest is not discovered till mncli damage is done. 

 i\ll 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. It is 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 

 fi-uit 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 i)ropcl the bee forward at the rate of a mile 

 pi'r 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 calcu.lations on the latter 



" The Gypsy Moth is also a very general feeder, but, being a leaf-feeder, is easy to 

 reach with insecticides. — Eds.
