Dr. Thomas Edmondson, who has paid the debt of nature since we were there, possessed a collection of plants which had few (if any) competitors for variety and value in this country. His collection has been sold, in one lot, to Mr. Winans, who has prepared extensive houses for its reception, and who undoubtedly possesses the finest and most rare hothouse in North America. Great disappointment was expressed that the plants were not sold separately, as a large company had assembled, to procure individual specimens. Mr. Winans swept the whole at a small advance, on the low valuation of $2,385. We noted the following, for their rarity: -

Fircrea gigantea; nine feet in diameter and ten feet high.

Cactus Braziliensis; twenty feet in height.

Mens reptans.

Banana Cavandishii; in bearing.

Sligmaphillon ciliatiana.

Muscienda frondosa.

Hakea Victoria; resembling the Salisburia.

Weigelia amabilis; an old plant, and in full bearing.

Magnolia grandiflora; a large plant; somewhat injured by the winter of 1855-6.

Stenocarpus Cunninghamia.

One of the most extraordinary things in these grounds, and one of the most beautiful we ever saw, was an Osage Orange-tree, about twenty-four years old. Its leading shoot had been destroyed, and it had become recumbent to a surprising degree. By pacing the circumference over which it had spread itself, we found it covered the space of one hundred and sixty-five feet 1 It is highly ornamental in this condition, and was full of fruit. The limbs laid about with a profusion that was positively beautiful and wonderful. We recommend experiments with this tree where a large space (say a circular drive) is to be filled.

Here, too, we gratified a long wished-for inspection of Dr. Edmondson's seedling camellias, which have stood out for twelve or fifteen years in the open air, protected only by leaves thrown over them. They were cut down to the snowline, the last winter, but were again growing vigorously, and sending up tufts of leaves more beautiful than mahonias. Would that our own climate might be favored with such a result. Dr. E., as already stated, was famous for possessing some extraordinary seedling strawberries of his own raising. The Marylandica constantly took the prizes, and other sorts were in great esteem. These have been purchased, and are now offered for sale by S. Feast & Sons (as before remarked), with the Charles's Favorite and Haarlem Orange. He never parted with these, his answer being always: " They are not for sale." His seedling strawberry ground was trenched from two to three feet deep; at the bottom of each trench, a layer of eight or ten inches of charcoal, manure, leather refuse, and various materials, were mixed. The seedling plants were turned out of the pots in which they had been kept all winter, and planted in rows two feet, and the plants eighteen inches apart. The ground was then covered with a thick coat of tan, the runners suppressed until fruiting was over.

The three now offered are the choice of many thousands tested. So notorious had his fruit become at the exhibitions and the markets, that no others attracted attention.

Marylandica is one of the finest show fruits. Color, rich dark crimson; large, firm, rich flavor; strong grower; well adapted as a fertilizer, and we think it the finest berry we know.

Haarlem Orange ripens early, and continues until strawberries are over; is a very prolific bearer, good size, and of a glossy orange color, pine-apple shape, firm, and of rich flavor, and a great favorite of the birds.

Charles's Favorite is declared to be equal to Hovey's Seedling, and ripens ten days earlier.

His camellias, now also in Mr. Feast's control, are Feast's Perfection, quite a remarkable flower, distinct from any other in color, and attracts all eyes, in collections however large.

Triumph of Baltimore is a very strong grower; large foliage, enormous flower, imbricated; color like tricolor, bat not so coarse, and very attractive.

Mary Kurtz is also a good one; fine foliage, free bloomer, fine-shaped flower, white ground, striped with rose; raised by Edward Kurtz, an amateur of merit.

The owners of these valuable articles, Samuel Feast & Sons, have been long and favorably known nurserymen and tenants of Dr. Edmondson. They have a very large nursery, a great variety of camellias, including some new and desirable kinds. Their prairie roses are too well known to be more than alluded to. Mr. S. Feast has been engaged, for some time, in planting orchards of pear, peach, and apple, for the supply of the Baltimore market, and if intelligence is any passport to success, he will soon show what may be done.

John Feast has a town greenhouse and garden, filled with the rarest and most beautiful flowers, and does a large business, supplying plants, bouquets, etc. etc.

Pentland & Brother are also largely engaged in the flower business, and have advertised, lately, some new roses, which promise well.

Baltimore may hereafter supply additional notes; at present, we reluctantly leave this most hospitable region.
