Ens. Horticulturist: - Pear trees have winter killed in Southern Wisconsin to such an extent as to discourage setting. We are subject to extremes of very severe cold weather, the thermometer sinking usually two or three times in the course of the winter 15 to 20 degrees below zero, and sometimes 25 to 30 degrees below; these cold spells are interspersed with mild, sunny, thawing days. Do you know, or do any of your contributors know, of any varieties of the Pear that will endure these extremes? If so, you will become the benefactors of this portion of the West by giving us the names and qualities of such varieties. Works on fruits do not enough discuss this specialty. J. C. S.

[We believe that in all sections of our country liable to extreme and sudden changes of weather, the list of Pears must be narrowed down to a very few. In such places none but close-grained, hard-wooded varieties can be depended upon, such as the Seckel, Buffam, Oswego, and others. Protection, in this connection, is indispensable; and quite important, too, is a low-headed tree. To treat this subject properly, would require several pages, and these we will very soon give to the subject. Our Western friends, however, may materially serve each other by sending in the names of such kinds as have best succeeded with them; for, after all, actual experience must finally decide the matter. All who contemplate planting fruit trees on the prairies should at once begin the planting of belts of timber for protection; its importance can not be overrated. The too rapid growth of the trees we suppose to be another difficulty, but one not alto-gether beyond control. - Ed].

Messrs. Mead & Woodward. - Inclosed I send specimens of insects that are devastating our cherry trees in this vicinity, and in some cases I have found them on apple trees also. Nothing of the kind has been noticed on cherry trees previous to this season. In some gardens the trees are nearly black with them and their labors. Yours truly, A. P. Peck.

Northampton, Mass., June 2, 1862.

[The insects inclosed are the. Black Aphis, the same that were last year so destructive to grain in many parts of the country. Fumigation with tobacco smoke, tobacco water applied with a syringe, the Gishurst compound, and whale oil soap applied in the same way, will destroy them. These remedies are all used in the green-house with sure results; but their wholesale application to large trees would prove a great labor. We know not how else, however, to get rid of them speedily. - Ed].

Editors of the Horticulturist: - You ought to come straight out to old Wayne and enjoy our fruits. "Seeing is believing," and eating is knowing, and I would like to have you know what fine fruit we have. Strawberries by the bushel; a few plates of those fine Burr's New Pine would make you, like a Broadway omnibus, at four o'clock, "going up, and all full inside." The birds have eaten all the May Bigarreau Cherries, but the Gov. Wood and Tartarean, Black Eagle, Elton, and Rockport Bigarreau, will soon be ripe, to be followed by the Doolittle, the Antwerps, and the Brinekle, and the Lawtons; and chiming-in to the same sweet stomach strains, the music of the apricots and peaches would fall harmoniously on the palate, the Seckel and the Fondante would play the tenor, while the Easter Beurre and the Duchess, will soon be large enough for thorough-bass. Now, if you have any music in your large souls, come on, and we will moisten the "thousand strings of your harp" with some pure American Oporto.

Lyons, June 16th, 1862. Yours, etc, Sylvester.

[The above was not intended for publication, but there is too much dry humor in it to be lost, notwithstanding it ends with a wet subject. We know we ought to go "straight out to old Wayne," and would if we could; but as we can't just now, are we to lose all those fine things, and the music and Port besides? What a Tantalus you are, to put in our sight, yet beyond our reach, such tempting things as the New Pine, Gov. Wood, Black Eagle, Elton, Brinckle, Seckel, Fondante, and pure Port! and this last must be good if made pure from your grape. We have now seen enough of it to be convinced of that. But look out for us till we come. - Ed].

Messrs. Editors, - Being in a quandary, I appeal to you for assistance. In the Spring of 1861, I grafted a Delaware shoot upon an old Isabella root. It took very well, but, unfortunately, a contraband destroyed it, and I permitted one shoot from the old root to grow. It made about thirty feet of new wood. Wishing the vine to run on a trellis 18 feet off, I laid it down, covering about three feet at the foot of the trellis with earth, and about the same length half way between the root and trellis; leaving the balance clear of the ground, in some places perhaps a foot. I did not bury the whole, for fear it would decay. The buds, of course, have thrown up shoots, many of them 18 inches high. So far I have permitted them to grow.

I contemplate burying the whole vine this fall, cutting off the new shoots to two or three buds to form roots. Now what I want to know is; did I do right in laying down such a length of new wood? Would it have injured the vine to have buried the whole? Would you let the shoots grow or pinch them off] Would it be better to bury the vine 1 If so, when? The old vine and root not being in the way at all, and having as many as I have room for besides, do you consider the old root any advantage to the new vine, provided the buried part at the trellis makes the usual amount of roots? Would you cut it off or let it stay? If cut, when? Next fall, I intend moving another vine the same way, and about the same distance, and would like to have your opinion through your valuable journal. Does it injure the fruit to have two varieties of vines on the same trellis, one above another? A place in your journal for answers to these Questions will very much oblige one who has a decided touch of the Graph fever.

Dover, May 31st, 1862.

[There is no necessity for laying down such a length of wood; two or three feet at the end will fully answer the purpose. The shoots should be pinched off. We would not bury the vine, but cut it off about four feet from the end where it has rooted, the old root and vine, of course, being removed. Be sure, however, that the end has rooted nicely before you do this. We do not consider the old root of any advantage after the buried part has become well established, and we should, as remarked above, cut it off. It may be done this fall or next spring, but we should do it this fall, and treat the end as directed for young vines. In the other vine referred to, simply bury about three feet of the end, and allow no shoots to grow in the intermediate space. It does not injure the fruit to grow two varieties on a trellis in the manner alluded to; but it does injure it to grow them this way on an arbor. To be more explicit, if vines are grown horizontal!/ one above the other on an arbor, the one beneath will produce poor fruit, whether it be the same kind or not. - Ed].

Editors OF the Horticulturist : - Can you, or any of your correspondents, tell me of a remedy or effectual means for the destruction of the grasshopper where it is not practicable to keep poultry? They last summer- destroyed several new and valuable evergreens of small size, and badly damaged others.

Harrisburgh, June 9, 1862. E. Manning.

[We do not know of any effectual means of destroying grasshoppers, except keeping poultry, especially a large flock of turkeys. Can any of our readers help Mr. Manning to a remedy in this case. - Ed].
