it feeds upon the young foliage. Its number is 

 then ahnost incredible, — more than one thousand 

 being accommodated on both surfaces of a leaf one 

 inch in length. The young sometimes lie two deep, 

 only caring for room to run their beaks into the 

 tissue of the leaf and feed upon the juices of the 

 tree. The foliage is often black with them. It is 

 necessary that the cultivator should use the prepa- 

 ration of whale-oil soap, as recommended for the 

 apple louse (Fitch).

 Knock. " This insect is chestnut-brown in color ; 

 smooth, covered with little impressed dots ; each 

 wing-case having two or three slightly elevated 

 longitudinal lines. The breast is clothed with 

 yellowish down." It is about an inch in length, 

 and feeds upon the leaves. It can be shaken from 

 the tree in the morning upon sheets, and burned ; 

 or killed by immersion in hot water. The grub, 

 while in the earth, lives upon young roots (Harris).
