within is something of a puzzle ; for, while it is not diffi- 

 cult to find the hole by which they leave the chestnut, 

 no one can see how they got in. The chestnut-borer, a 

 beetle, bores a tiny hole in the nut, and deposits therein 

 her eggs. These eggs hatch out into footless grubs that 

 eat their way out of the chestnut by means of strong 

 jaws, which move vertically, instead of 

 sideways like those of other insect 

 larvae. These grubs pupate in the 

 ground, emerging thence full-grown 

 weevils, which repeat the egg-laying 

 process with the same results. 



The tree itself is one of the largest 

 and tallest of our forest trees and a very 

 rapid grower. Because of this, while 

 the young bark is remarkably smooth, 

 the bark of the trunk is hard and chestnut weevii. 



Chestnut Grub. 



rugged, with deep clefts. It has split 



repeatedly in order to accommodate the growth within. 



The leaves are long and very lovely in texture and 

 in color. The wood makes valuable timber. It is both 

 durable and beautiful, admitting of a high polish. 



It makes a profitable orchard because of its quick 

 growth and the demand for its fruit. From it, in southern 

 Europe, is made a flour much used by the poorer people. 



The chestnut tree attains a great age and size. On 

 top of Mount ^Etna is a famous tree called the Tree of a 

 Himdred Horsemen, from the fact that it once sheltered 

 a hundred cavaliers.
