OF FRUIT TREES. 99 



in this first state, they soon, by their growth, be- 

 come straitened for room ; and, having also con- 

 sumed the nearest forage, they march and take a 

 new station, and there form a new, but more am- 

 ple tent. By such neglect the mischief of their 

 ravages is increased, and they are with more diffi- 

 culty destroyed. 



The efficient and convenient instrument above 

 mentioned, for this work, is nothing more than a 

 common bottle brush fastened on the end of a pole. 

 Having an old one in my house, I was enabled to 

 make the experiment on the day when the idea of 

 so applying it occurred to me. This brush is made 

 of hog's bristles, introduced between two stiff wires 

 closely twisted, and, being convenient in cleansing 

 the insides of bottles, is probably familiarly known 

 wherever liquors are bottled. For the information 

 of others, I will mention, that a piece of wire, full 

 one tenth of an inch in diameter, about three feet 

 long, doubled, and leaving a small loop in the mid-, 

 die, is closely twisted for the length of about eight 

 or ten inches from the loop ; and then the bristles, 

 being introduced between the remainder of the 

 two branches of the wire, and these closely twisted 

 upon them, the bristles are immoveably fixed, and 

 thus form (after being uniformly sheared,) a cylin- 

 drical brush, about six inches long, and two inches 

 and a half in diameter. To fasten this conveniently 

 to a pole, with a small gouge, I made a groove about 

 seven or eight inches long at the small end of the 

 pole, in which nearly all the handle (the naked por- 

 tion of the twisted wire) of the brush was laid, and 

 bound on with three strings. 



In using the brush, press it on the small nest, and 

 turning the pole in the hand, the web is entangled 

 with the bristles and removed ; otherwise you rub 

 the fork of the limb, inside and outside, with the 

 brush, when" nest and worms are surely killed or 

 brought down. That the experimenter may see
