Living in a plum growing district, where the fruit is produced in great perfection and abundance, I may claim a right to know something about plums and plum trees. I therefore send you a few scraps from my Note Book, in hopes they may be of some benefit to those who are not similarly blessed.

1. Peach Plum

I am well satisfied of the impossiblity of successfully cultivating this plum to the northward of New-York. The winters are so severe as to destroy nearly every year the new wood and blossom-buds; consequently fruit from this variety is very rarely obtained. I have grown it for the last twenty-two years; in the nursery, frequently, hundreds of trees are entirely destroyed, rarely showing a symptom of vitality on the approach of vegetation the ensuing season.

2. Lombard

This variety of native origin, is certainly one of the most profitable plums, for orchard culture, that has as yet come under my notice - not only producing enormous crops of perfect fruit, annually, but at the same time growing vigorously with ordinary attention, accommodating itself to almost every variety of soil; a great desideratum in my opinion, for such soils as are not adapted to the general cultivation of the plum.

3. Schenectady Catharim

A variety peculiar to this locality, where it has enjoyed the reputation of a first rate fruit, and deservedly so, as it posseses all the qualities desired, except large size - i. e., hardy, extremely productive, and of a flavor but rarely excelled.

4. Coz's Golden Drop

A great favorite wherever it is generally known; this plum has already been extensively planted in this city, although I opine it will not be very profitable to the market grower, as it is rather a shy bearer; but its late maturity and excellent flavor, will always command a place for it in the kitchen and amateur garden.

5. Coz's Late Red

Has been somewhat over praised, as it has nothing to commend it but the lateness of its ripening season. [A quite correct opinion for your latitude, but farther south it is a valuable fruit. Ed.]

6. Columbia

I have fruited for the last five years; my experience, during which time, goes to prove it hardly worthy of the high encomiums which have so frequently been beand Ida Gage. To produce its fruit in perfection, (north of New-York,) it requires a warm, deep soil, with a southern inclination; and on a wall, with the latter mentioned exposure, it can be grown to twice its usual size and beauty.

9. Prince's Imperial Gage

A well known and extensively cultivated variety, on which the grower can calculate to a certainty the number of bushels of fruit he can annually carry to market. This fact, connected with its other good qualities, will keep it in cultivation when other higher flavored sorts are comparatively abandoned.

10. Huling's Superb

This mammoth fruit docs not seem to have attracted that universal notice to which it is entitled in so eminent a degree. It is a decided anomaly in this class of fruits, carrying out its gigantic proportions in wood, foliage, and fruit. It is tolerably hardy, a good or ordinary bearer, fruit of the largest size, etc.- superior flavor.

11. Bluz Imperatrice

A very late plum - decidedly superior to Coe's Late Red in this latitude.

12. Jefferson

An excellent plum in all respects; a little tender here, and very difficult of propagation to any extent.

13. Lawrences Favorite

Has proved itself highly deserving of the numberless culo-giums so unsparingly bestowed upon it by those who have partaken of its highly delicious fruit. The tree is a strong grower, quite hardy, differing very materially in this respect from the Jefferson.

14. Purple Magnum Bonum

A very ordinary plum, frequently reproducing itself from seed, with scarcely any perceptible difference of habit or fruit. One of these seedlings is "Duane Purple," which does not differ materially from a half dozen other seedlings cultivated here, under the name of Red Magnum Bonum.

15. Yellow Magnum Bonum(Or Egg Plum,)

15. Yellow Magnum Bonum(or Egg Plum,) is quite a favorite here, being very hardy, productive, late, and consequently a very profitable plum for market.

16. Martin's Siedling

A new yellow plum, which originated in the garden of the gentleman whose name it bears, residing in this city; it has fruited with me this last summer, and proves to be a plum of the finest quality, superior to the majority of highly lauded foreign varieties.

17. Mediterranean

Another new seedling from the interior of this slate, nearly as large as the Peach plum; superior to it in point of flavor, and some six days earlier. It forms a beautiful, thrifty growing tree, perfectly hardy. Ripens the latter part of July and first of August.

18. Washington

A magnificent showy plum, of very good flavor; hardy and productive; a general favorite.

19. Early Royal

Rather tender; a slow grower; very productive; an excellent, high flavored fruit; ripens the latter part of July.
