the difference. The apple cui-culio spreads with 

 extraordinary rapidity, and destroys the greater 

 pai't of the apple ci-op of Illinois. The plum 

 curculio stings, but does not breed in the apple : 

 the apple curculio makes a round cut. difficult to 

 see with the eye. The worm i(iii;iiiis wlicrc the 

 egg was laid lintil it matures, w licii it cdims out 

 and goes into the gi-ound. He hoped tliis would 

 turn out to be the apple curculio. It is the apple 

 or plum curculio. for only one kind has been 

 seen to-day. Curculio can not fly under a tem- 

 perature of 70 degrees. They fly against tlie 

 wind ; but as yet he had been unable to determine 

 the extent to which they migrate. Whether this 

 be the apple or plum curculio, a great discovery 

 lius been made." 



All wliich verily surprised us. What! tliecom- 

 1 lined entomological and horticultural wisdom 

 of Illinois not able to distinguish between the 

 Plum and the Apple Curculio? Dr. LeBaron, 

 so lar as we are aware, has never claimed to be 

 ae(|uainted with the Apple Curculio, and we 

 believe it is of quite rare occurrence around 

 Geneva : he might therefore justly be cautions in 

 I lie matter. But what shall we say of Dr. Hull, 

 wlio has so often spoken of the Apple Curculio, 

 and dwelt upon its habits, before horticultural 

 liodics; and who must have slain such hosts of 

 the Plum Curculio with his powerful and pon- 

 derous machine. Not able to distinguish be- 

 tween these two insects ? Why, they differ more 

 in tlie eyes of an entomologist than a sheep does 

 from a cow ! 



The snout of the Plum CnvciiMo {Conotrachei us 

 nenuphar) hangs down like the trunk of an ele- 

 phant : it is short, stout, and does not admit of 

 being stretched out horizontally foi-wards ; and, 

 as may be seen by referring to our Figure 92, is 

 scarcely as long as the head and thorax together, 

 and can be folded back between the legs, where 

 thei'e is a groove to receive it. The Plum 

 Cm'culio is broadest across the shoulders and 

 narrows behind, and moreover, the black sealing- 

 wax-like, knife-edged elevations on the back, with 

 the pale band behind them, characterize it at once 

 from all our other fruit-boring snoutrbcetles. 



The Apple, or Four-humped Curculio (Anih- 

 onomus quadrigibbus, Say), is a much smaller 

 insect, with a snout wliich sticks out more or less 

 hoi-izontally and cannot be folded under, and 

 which is as long as the whole body. This insect 

 has narrow shoulders and broadens behind, 

 where it is furnished with four very conspicuous 

 humps, from wliich it takes its name. It has 

 neither the polished black elevations nor the pale 

 band of the Plum Curculio. In short, it difters 

 generically, and does not attack the peach. 



If the St. Josephites were a wine-growing, 

 instead of a peach-gi-owiug people, we might, 

 in our own minds, have been able to account for 



this lack of disci-imination on the part of one who 

 has said so much about both insects ; but as it is 

 (lor the tax on peach-brandy must certainly pre- 

 clude its manufacture tliere) we can give no 

 other explanation than — well, more anon! 



THE DEATH-WEB OF YOUXG TROUT. 



anal e.xtremity— all the flguii'S 



The culture offish, and especially of the Trout, 

 is attracting deserved attention in this country, 

 from many persons who are at all favorably 

 situated for carrying it on. The idea of propa- 

 gating fish artificially is comparatively modern, 

 and when we reflect on the success of the enter- 

 prise, notwithstanding those who first talked 

 about it were looked upon as idle theorists; we 

 yet have faith that, some of these days, certain 

 beneficial and parasitic insects will to some ex- 

 tent be propagated and introduced into one 

 country from another— Utopian and chimerical 

 as the idea may now appear to most persons. 



To-day fish-culture has grown to be a most 

 important and lucrative business in some parts 

 of Europe, and it is fast acquiring importance 

 in this country. It is an art yet in its infancy, 

 and the few enterprising men who embark in it, 

 in this country, will naturally meet with ad- 

 verses, and must gradually perfect their art by 

 dear-bought experience. Anything which will 

 lead to a better understanding of the obstacles 

 which render the business precarious, will 

 therefore tend to perfect the art, and must be 

 welcomed by those interested.
