are deposited near the extremities of the small branches of the apple 

 tree, in the form of circular rings or cylinders round them. 



The above figure represents one of these rings of eggs. Here they 

 remain till the following spring, when they hatch, grow, and propa- 

 gate their species again as before. By far the best time to destroy 

 them is in winter, or very early in spring. These rings of eggs are 

 quickly seen by a practiced eye, and by means of a ladder they may 

 be rapidly gathered into a basket, and burnt. If the eggs are suffer- 

 ed to hatch, then use the hand for their destruction, by grasping the 

 whole nest at once and crushing them. Mittens may be used if one 

 is averse to touching them. These insects, which many years ago 

 were so destructive, almost disappeared in Western New- York for a 

 while, but appear to be now rapidly increasing. Vigorous efforts 

 should therefore be made to destroy them. 



The canker-worm^ which crawls up the trunk of apple trees, and 

 devours the foliage, and which has proved so eminently destructive 

 in some parts of New-England, appears to be unknown in the State 

 of New- York. 



Jlphides, or plant-lice, including a species with long white down 

 called American Blighty are often injurious to young trees. The 

 common or green species, which cover the lower surface of the leaves, 

 are easily destroyed by a solution of whale, oil-soap in water, half a 

 pint of soap being added to half a pint of water. The " American 

 blight" which covers the young branches may be destroyed by lime 

 whitewash. 



The horer, which has proved injurious and destructive to the apple 

 tree in some places, cuts into the solid wood near the ground. If the 

 trees b^ examined annually, and before it has penetrated deeply, it is 

 easily found and destroyed. But it may afterwards be extracted from 

 the deeper holes by means of a flexible barbed wire, or punched to 

 death without extracting, by a flexible twig.
