and of a uniform red color; that it remains in this state an 

 indefinite period, dependent on the weather, usually prefer- 

 ring to issue after a warm rain. 



24. That in a stiff clay soil a severe drought will kill many 

 of them while in this last named condition, and that larvae 

 contained in stone fruits that fall upon naked plowed ground 

 where the sun can strike them, generally die. 



"This catalogue might be lengthened, but already embraces 

 all the more important facts, and I think they sufficiently 

 prove that the curculio is single brooded. There is, it is 

 true, no particular reason why the earliest developed curcu- 

 lios, or those which issue from the ground during the fore 

 part of July, should not pair and deposit its eggs again, 

 other than it does not appear to be their nature to do so. 

 Such an occurrence is by no means an isolated one in insect 

 life; and aside from the fact that late fruit is almost entirely 

 exempt from them, we have the experiments of Dr. Trimble, 

 which indicate that they have to pass tlirough the Winter be- 

 fore being able to reproduce their kind." 



Next, Mr. R. gives a list of the cannibal insects that de- 

 stroy the curculio, which we omit, although valuable. Among 

 the natural remedies, he says a few words in favor of hogs as 

 curculio destroyers, "Abundant proof might be adduced of 

 their utility in an orchard, especially during the first season, 

 but I will mention only the case of Messrs. Winters Bros., of 

 Du Quain, Illinois. These gentlemen, for the past five years, 

 have kept a large drove of hogs in their extensive peach or- 

 chard, and have been remarkably exempt from the attacks of 

 the 'Little Turk: While at their place last Fall, I noticed 

 that all the trees were banked up with earth to the height of 

 over a foot, which prevented the hogs from injuring the 

 trunks. They have never had occasion to shake their trees, 

 and consider one hog to the acre sufficient to devour all the 

 fallen fruit, the hogs being fed only during the Winter. The 

 efficacy of this hog remedy depends a great deal on how one's 

 orchard is isolated from those of others, for it is very evident 

 that it will avail but little for- one farmer to destroy all his 

 curculio, while his neighbors are breeding them by thousands,
