The production of apples in Western New-York, for 1851, was not as large as usual; and the scarcity both east and west of us, at Rochester, created a demand more than equal to what could be well spared .from home consumption - so that at this moment it is barely possible to obtain a single barrel of choice ones.

The qualities grown were in many instances superior, but oftetier with great defects.

It may be said that the apple trees planted within the last fifteen or twenty years, are now as fruitful as ever, and bear as fair fruit as they will. Insects and blight affect the trees frequently, and some seasons the fruit is not as good as in other years.

I did myself the honor to send you in 1847, (see Horticultural vol. 1, p. 482,) samples of several kinds grown with us, and now forward you specimens of choice ones - so that you may judge how well they compare. You will find:

Northern Spy.

Canada Red or Nonsuch.

Herefordshire Pcarmain.

Swaar.

Pomme Grise.

Esopus Spitzenbergh.

Green Sweeting.

The " Canada Reds" sent, are the finest I have ever seen of the kind, and I am free to admit them a very, very choice apple, and a good keeper. The " Northern Spy" I have found to bear me out in all that has been said in its favor, and I am sure a better, or more choice barrel of fruit, has never been sent to Europe, than one of that kind which I packed the past week to send there, which Dr. Lindley, Mr. Rivers, and all the nurserymen in and about London, are to have the privilege of tasting.

Of their keeping qualities, let me tell you. I put my "Spys" as late in the fall as possible, and very soon after they are gathered, intoa cellar, kept cool by having a pane of glass taken out of the window, (which remains out all winter,) and place them on wooden frames, about 12 inches from the bottom of the cellar, (the bottom a ground one,) and there let them stand till the first of March. If well selected, the fruit will open sound, and well colored, with a fragrance equalling anything of the fruit kind. About this time they commence ripening, and if pains are taken to head up the barrel, as the fruit is taken out for use, so that the air is excluded, they will keep till June. This is my plan, founded upon experience.

Many of the trees grafted are producing the " Northern Spys," and all I have seen thus far, have been choice; and persons growing them hesitate not to charge a dollar per bushel, and get it too.

Trusting you may get the fruit safe, I remain truly, James II. Watts. Rochester, March 8, 1852.

The apples were received in perfect order, and our correspondent will please accept our thanks for the beautiful pomonal display. The Northern Spys, (for which Rochester is the meridian,) were the handsomest specimens - and very sprightly and refreshing in flavor. The Canada Red, or old Nonsuch of New-England, is, to our taste, one of the finest of apples - really superior in flavor to the Northern Spy. Its merits as a dessert fruit, have long been known, but in New-Eng\and and Long-Island, where it has been most cultivated, it is rather a shy bearer. In Western New-York, it is, we believe, quite prolific, and we certainly know few apples better worth planting, in a rich, deep soil, than this variety.

The Fpocimens of Swaar and Spitzenlergh, were very handsome - but not so high flavored as the same sorts grown on the Hudson.
