Numerous communications respecting the effects of the late winter have reached us. From the number we have selected several which have been published lately, and have to regret that space precludes the insertion of all. One in particular, from our valued correspondent George L. Taylor, Esq., of Chicago, Illinois, we should have been glad to copy. He says: "I, for one, am not discouraged, though we fared badly here with our fruit-trees. The motto of the arboriculturist should ever be, 'Nil desperandnm.' The Garden City, each recurring spring, looks and becomes more worthy of the name, and that the Horticulturist has within the past two years more than doubled its list of Chicago subscribers, evinces a more settled purpose and growing taste in these matters, which are sources of congratulation to every friend of the cause and lover of his country".

The Pear Crop etc., writes a valued correspondent, is light in Rochester, N Y., and vicinity. The same remark applies here, and in Boston, though Mr. Hovey's fine trees have more than an average. The trees flowered well in most neighborhoods, but much of the fruit fell before it was fully established. Mr. Wilder's extensive collection will produce rather mote than: half a crop. We should say, after an- extensive tour, that pears this year would nowhere be as abundant as was hoped, and the peach-crop poor.

The Forest-trees of America, by R. U. Piper, M. D., Woburn, Mass., is the title of a quarto livraison well printed, which we picked up in Boston the other day. It appears to us to aim at describing many things which have been described before; the Horticulturist, old and new, is quoted extensively; the pictures are well drawn and printed, but we do not yet quite discover its aim or drift.

The Flower Garden, or Breck's Book of Flowers, is a new edition revised and enlarged of the excellent Boston Seedsman and Cultivator, Mr. Joseph Breck. It contains much valuable information of a practical kind, and may usefully be employed as a guide.

H. A. Dreer, Seedsman, 117 Chestnut St., Philadelphia, advertises seeds suitable for the season. Especially he recommends his Extra Pansies, which took the premium in April last, and have been saved with care.

The Late Winter #1

April, 1857, will be remembered, in this section, as the month of snow. On the 1st, we had a moderate fall; on the 6th, and again on the 14th and 15th. Bot the great storm of the season was on the 20th and 21st, when the burden borne by the evergreens bent them almost perpendicularly. Many old apple-trees were, broken down.

A thaw commenced on the afternoon of the 21st, when the burden of snow on branches of deciduous trees, and the south and west sides of evergreens, fell off; yet, on the northeast side of trees exposed to the wind, a novel feature was presented on the morning of the 22d - tall columns of snow extending one-third around their trunk, and terminating in a sharp edge to the northeast (frozen like ice), and extending upward, following the taper of the trunk and leading branches, sometimes to the height of forty feet. We measured one of these untimely appendages at about four feet from the ground, and found the horizontal depth of this columnar mass of snow encased in ice, to be ten inches, this always varying, however, to the size of the tree.

The actual quantity of snow on the ground, on the morning of the 22d, was fifteen inches. When we take into account the amount of moisture on the surface to help melt the snow, and the moist condition of the snow in falling, it is but a fair estimate to suppose the quantity of snow that fell in this storm was thirty inches, or two and one-half feet, which makes it decidedly the heaviest storm ever known here at this season of the year. The thermometer, during the storm, ranged, on the 20th, 32° to 34°; on the 21st, it rose to 38°, but fell at night to 30°. The wind was northeast most of the time; a stiff breeze, and, in the night, very high.

The winter has been marked by some intensely cold terms. In each of the months (December, January, February, and March), the mercury was below zero. The coldest term was in January, when the mercury was, in one instance, 23° below, and remained below through the day. The next morning, noted 20° below zero; yet our peach and other fruit buds are apparently uninjured. The new wood of last year's growth stands firm and good, thus giving new evidence that the descent of the mercary to 17° below zero does not kill buds.

Our experience with mice, the last winter, has been to us truly novel. We had apple-trees standing in grass land, and, within a few feet of them, trees standing in stubble, stocked a year ago. These latter were effectually protected, as I supposed, by putting piles of thoroughly rotted manure around them, well elevated at the trunk of the trees. When the frost came out this spring, we went to level the manure, and were surprised and vexed to find several fatally girdled, the work of destruction being carried from near the surface of the manure into the roots. In two or three instances, we found mice nests in the manure, the material having been brought from a distance. At one tree, we found the mischief-dealing population, which we despatched with right good will. This experience brings us to the conclusion, that mounds of well-rotted manure do not fully protect, especially when mice are very plenty or very hungry, or very much bent on mischief. Not one of the trees on grass land was molested, though no protection was given.

The Late Winter #2

A valued correspondent says: "I would advise you to repeat your trip to Cuba next fall, to get away from our Nova Zembla winter. The last exceeded all in my memory. It has actually killed several of the oldest paper-mulberries in Newark, N. J., streets, and at Astoria, N. Y., I observed no indication of life in two venerable Catalpas which must have braved thirty or forty winters, facing N. N. W.
