wings of the siiw-lly generally. They are transparent, reflecting the changeable colors of the 

 ri\inl>(>w, and have a i»nioky tinge, forming a cloutl or broad band across the middle of the fir^^t 

 pair; the veins are brownish. The boily of the female mca'^ures rather more than ont-fifth of 

 an inch in leni;th ; that of the male is smaller. In the year 1S28, 1 ol)served those eaw-flies on 

 Cherry and Plum trees, in Milton, on the tenth of May; but they usually appear towards the 

 end of May or beginning ol June. Soon afterwards some of them begin to lay their eggs, and 

 all of them fiuisli this williin three weeks, and di.siipj)car. Their eggs are ]ilaced singly within 

 little semicircular incisions through the skin of the lenf, and generally on the under side of it. 

 On the fourteenth day afterwards the eggs begin to hatch, and the young slug-woi'ms continue 

 to come forth from the 5th of June till the 20th of Jidy." They attain their growth in twenty- 

 six days, leave the trees, and burrow in the ground. In sixteen days their transformation is 

 completed, and they emerge from the ground in the fly state, and commence to lay eggs for 

 another brood. "We have not often, however, more than one brood in one season. 



We know of no better remedy tiian dusting with lime or ashes, and this we admit to be some- 

 what diftieult in the case of large trees. Among the nursery rows we use dry, fine earth, aa 

 we get it among the trees; and it answers the i)urj)oso. 



The August number of the ITorllevlturist is received, and your answer to a subscriber at Elkton, Todd Co., Ky., 



rolaiive to some diseased A])i)lc twigs sent you. I do not wisli to be troublesome, but would be glad to hear further 

 from you, relative to the disease known with yju, as flre-bliglit. What we eall flri-blight in the West, may ditTer 

 from what is known as that disease with you. Is the wood as well as the foliage killed in Dre-blight, as liir as the 

 disease extends? (1) 



In the diseased trees, of which I sent you a specimen, the foliage alone is killed, although the wood, and sometimefl 

 the fruit, is covered with the same sorts of deposit. The wood does not appear to be injured by it, but ren)ains plump 

 and healthy, and with a firm belief that it was the work of an insect, I have put in thousands of grafts, which were 

 covered with it at the time. The older and less thrifty trees are more liable to be attacked than others ; of both the 

 Apple and the Pear. However, I have noticed some exceptions to this rule. J. S. Downer, — Elkton, Ky. 



(1) It is; and, as a general thing, the woody portion of the tree is aff"ectcd with the disease, 

 bejond recovery, before a leaf turns black. The first indication of the disease is often the sour 

 smell which it emits, especially when a tree is first taken and is yet full of sap. It seems to 

 operate principally on the newl^'-formed parts immediately under the baik. It spreads among 

 tlie circulating fluids with great rapidity, so that a tree may in fact be dead without a leaf being 

 withered or black. If the attack is discovered early, and the affected branch or portion of 

 bark be cut cleanly and thoroughly out, leaving r.o trace of the disease, the tree will recover. — 

 TVe have ourselves saved a large number of trees in this way ; but if neglected a day, or in 

 some cases a few hours, the disease becomes deeplj' seated, and the tree is in a hopeless case. — 

 Sometimes, as the subject is more or less suscej)tible, the leaves turn black immediately ; while 

 in others, where a portion of the wood remains sound enough to keep up a sort of communica- 

 tion between the roots and leaves, the latter will remain green, or a sickly -looking green, for a 

 whole season. In some cases trees recover without any aid. These are when the circulation 

 of the fluids is very slow, as in old or stunted trees ; the disease attacks a branch or portion of 

 the tree, and expends its venom without affecting the principal channels in which the vital fluids 



circulate.

Evergreen- llEncES.— Will you please inform me of the best time and mode of trimming a Hemlock hedge which 

 was set out about the S.Oth of May. It is not that its rapid growth demands any very vigorous pruning, but because 

 it is so thin and straggling. A Constant Header. 



Let it alone till next spring, and shear it just before new growth commences. If your plants 



ate small, they will thicken without much shearing ; but if tall or thin, they will scarcely ever 



make a good hedge. 



♦ 



Will you please inform me, through the ITorticulturUt, by what rule, in your opinion, one should be governed, 

 in figuring any fruit to be placed before the public, as a representation of the fruit produced by any plant? Should 

 the extra or largest fruits be selected, the average size, or what size ? J. J. — Boston. 



own rule is to select fair average specimens produced under good culture ; the very larg' 

 smallest would of course convey an erroneous idea of the fruit.
