It is scarcely necessary to explain that several of our com- 

 mon oaks blossom in the spring and set acorns that ripen the 

 following fall. Other oaks form acorns at the time of blooming 

 which grow but little until the following spring. They then begin 

 to develop and during the ensuing autumn mature and drop from 

 the trees. The following lists show our species of native oaks be- 

 longing to each class. 



ANNUAL-FRUITING OAKS. White, Post or Iron, Bur or 

 Mossy-cup, Swamp White, Yellow and Chestnut Oaks. 



BIENNIAL-FRUITING OAKS, Red, Swamp Spanish or 

 Pin, Scarlet, Black or, Yellow-barked, Spanish, Bear or Scrub, 

 Black Jack or Jack, and Laurel or Shingle Oaks. , 



CLASSES OF INSECTS THAT INJURE NUTS. 



Nuts are attacked by a great variety of insects but the most 

 serious injuries are done by moths and snout beetles. Thr larvae 

 of several species of moths may be found in chestnuts, beech- 

 nuts and acorns, particularly in nuts that have their shells bro- 

 ken so as to permit easy entrance to the kernel by the insects. 

 The damage wrought by the class of insects known as snout 

 beetles, however, is greatly in excess of that done by ail other 

 kinds combined. 



The term "snout beetle" is applied to the adults of the 

 group of insects which forms the subject of this paper on ac- 

 count of the peculiar structure of the head, the front part of 

 which is prolonged into a snout or proboscis. In some species 

 this snout is short and stout and in others it is long, slender 

 and wire-like. In the females of some of the nut weevils it is 

 longer than the rest of the body. The mouth, which is armed 

 with a minute but strong pair of jaws, is situated on the apex 

 of the snout and the appendage is used for piercing or punctur 

 ing various kinds of plant tissue to obtain food and to provide an 

 opening in which to deposit eggs.
