214 INDIRECT INJURIES CAUSED BY INSECTS, 



The seeds of forest- as well as of fruit-trees are doubts 

 less subject to injuries from the same quarter, but these 

 bein£rmore out of the reach of observation, have not been 

 much noticed. Acorns, however, a considerable article 

 with nurserymen, are said to have both a moth and a 

 beetle that prey upon them; and what is remarkable, 

 though sometimes one larva of each is found in the same 

 acorn, yet two of either kind are never to be met with 

 together ^. The beetle is probably the Curculio Glandium 

 [Balaninus) of Mr. Marsharn, and is nearly related to 

 the species whose grub inhabits the nut. 



Having now conducted you round and exhibited to 

 von the melancholy proofs of the universal dominion of 

 insects over our vegetable treasures, while growing or 

 endued with the principle of vitality, in their separate 

 departments, — I must next introduce you to a pest worse 

 than all put together, which indiscriminately attacks and 

 destroys every vegetable substance that the earth pro- 

 duces, and which, wherever it prevails, carries famine, 

 pestilence and death in its train. Happily for this coun- 

 ti-y — and we cannot be too thankful for the privilege, we 

 know this scourge of nations only by report. The name 

 of Locust, which has been such a sound of horror in 

 other countries, here only sugge:sts an object of interest- 

 ing inquir3\ But the ravages of locusts are so copious 

 a theme that they merit to be considered in a separate 

 letter. I am, &c.
