Canker-worm.—The male moth has pale-ash colored wings, with a black dot, and is about an inch across. The female has no wings, is oval in form, dark-ash colored above, and gray underneath. These rise from the ground as early in spring as the frost is out. Some few rise in the fall. The females travel slowly up the body of the tree, while the winged males fly about to pair with them. Soon you may discover the eggs laid, always in rows, in forks of branches and among the young twigs. Every female lays nearly a hundred, and covers them over carefully with a transparent, waterproof glue. The eggs hatch from May 1st to June 1st, according to the latitude and season, and come out an ash-colored worm with a yellow stripe. They are very voracious, sometimes entirely stripping an orchard of its foliage. At the end of about four weeks they descend to the ground, to remain in a chrysalis state, about four inches below the surface, until the following spring. These worms are very destructive in some parts of New England, and have been already very annoying, as far west as Iowa. They will be likely to be transported all over the country on young trees. Many remedies are proposed, but to present them all is only to confuse. The best of anything is sufficient. We present two, for the benefit of two classes of persons. For all who have care enough to attend to it, the best remedy is to bind a handful of straw around the tree, two feet from the ground, tied on with one band, and the ends allowed to stand out from the tree. The females, who can not fly, but only ascend the trunk by crawling, will get up under the straw, and may easily be killed, by striking a covered mallet on the straw, and against the tree below the band. This should be attended to every day during the short season of their ascent, and all will be destroyed. Burn the straw about the last of May. But those who are too indolent or busy to do this often till their season is past, may melt India-rubber over a hot fire, and smear bandages of cloth or leather previously put tight around the tree. This will prevent the female moth from crossing and reaching the limbs. Tar is used, but India-rubber is better, as weather will not injure it as it will tar, so as to allow the moth to pass over. Put this on early and well, and let it remain till the last of May. But the first, the process of killing them, is far the best.

      Gathering-and preserving.—All fruit, designed to be kept even for a few weeks, should be picked, and not shaken off, and laid, not dropped into a basket, and with equal care put into the barrels in which it is to be kept or transported. The barrel should be slightly shaken and filled entirely full. Let it stand open two days, to allow the fruit to sweat and throw off the excessive moisture. Then head up tight, and keep in a cool open shed until freezing weather; then keep where they can occasionally have good air, and in as cool a place as possible, without danger of freezing. Of all the methods of keeping apples on shelves, buried as potatoes, in various other articles, as chaff, sawdust, &c., this is, on the whole, the best and cheapest. Wrapping the apples in paper before putting them into the barrels, may be an improvement. Apples gathered just before hard frosts, or as they are beginning to ripen, but before many have fallen from the trees, and packed as above, and the barrels laid on their sides in a good dry, dark cellar, where air can occasionally be admitted, can be kept in perfection from six to eight weeks, after the ordinary time for their decay. Apples for cider, or other immediate use, may be shaken off upon mats or blankets spread under the tree for that purpose. They are not quite so valuable, but it saves times in gathering.

      Varieties are exceedingly numerous and uncertain. Cole estimates that two millions of varieties have been produced in the single state of Maine, and that thousands of kinds may there be found superior to those generally recommended in the fruit-books. The minute description of fruits is not of the least use to one out of ten thousand cultivators. The best pomologists differ in the names and descriptions of the various fruits. Some varieties have as many as twenty-five synonyms. Of what use, then, is the minute description of the hundred and seventy-seven varieties of Cole's American fruit-book, or of the vast numbers described by Downing, Elliott, Barry, and Hooper? The best pear we saw in Illinois could not be identified in Elliott's fruit-book by a practical fruit-grower. We had in our orchard in Ohio a single apple-tree, producing a large yield of one of the very best apples we ever saw; it was called Natural Beauty. We could not learn from the fruit-books what it was. We took it to an amateur cultivator of thirty years' experience, and he could not identify it. This is a fair view of the condition of the nomenclature of fruits. The London experimental gardens are doing much to systemize it, and the most scientific growers are congratulating them on their success. But it never can be any better than it is now. Varieties will increase more and more rapidly, and synonyms will be multiplied annually, and the modification of varieties by stocks, manures, climates, and location, will render it more and more confused.

      We can depend only upon our nurserymen to collect all improved varieties, and where we do not see the bearing-trees for ourselves, trust the nurseryman's description of the general qualities of fruit. Seldom, indeed, will a cultivator buy fruit-trees, and set out his orchard, and master the descriptions in the fruit-books, and after his trees come into bearing, minutely try them by all the marks to see whether he has been cheated, and, if so, take up the trees and put out others, to go the same round again, perhaps with no better success. Hence, if possible, let planters get trees from a nursery so near at hand that they may know the quality of the fruit of the trees from which the grafts are taken, get the most popular in their vicinity, and always secure a few scions from any extraordinary apple they may chance to taste. It is well, also, to deal only with the most honorable nurserymen. Remember that varieties will not do alike well in all localities. Many need acclimation. Every extensive cultivator should keep seedlings growing, with a view to new varieties, or modifications of old ones, adapted to his locality.

      We did think of describing minutely a few of the best varieties, adapted to the different seasons of the year. But we can see no advantage it would be to the great mass of cultivators, for whom this book is designed. Those who wish to acquaint themselves with those descriptions will purchase some of the best fruit-books. We shall content ourselves with giving the lists, recommended by the best authority, for different sections, followed by a general description of the qualities of a few of the best. Downing's lists are the following:—

      APPLES FOR MIDDLE AND SOUTHERN PORTIONS OF THE EASTERN STATES, RIPENING IN SUCCESSION.

      APPLES FOR THE NORTH.

      APPLES FOR THE WESTERN STATES,

      Made up from the contributions of twenty different cultivators, from five Western states.

      APPLES FOR THE SOUTH AND SOUTHWEST.
