This good old city of horticultural renown has long been the seat of a thriving and lucrative business in seeds. The venerable and excellent Bartram, and his neighbor, Marshall, in the infancy of our colonies supplied Europe with our native seeds, trees, and flowers. They dabbled, too, as their pleasant correspondence shows, a little in tortoises and snakes I The letters to their English friends and employers, as collected by Dr. Darlington, forms one of the very pleasanteat books of this or any age, especially to those interested in botanical subjects. I can not but wish the work accessible to every gardener, for whom Bartram was a model of industry, perseverance, and success. His beautiful old garden has fallen into the hands of Colonel Eastwick, long in the employment of the Emperor of Russia in the locomotive and railroad business, and he has carefully preserved the specimens of rare trees collected by Bartram, taken care of the old mansion built by Bartram's own hands, and now a picturesque object overrun with ivy coeval with the botanist himself.

No stranger who travels to our borders should omit to visit these now superb grounds, where he will find the finest specimen trees and shrubs in America. This garden, by the liberality of Colonel Eastwick, still supplies seeds from the trees of Bartram's collecting from Canada to Florida. Meehan & Saunders, of Germantown, who advertise in the June number of the Horticulturist, are liberally permitted to collect from this garden whatever will be valuable to horticulturists. It is something to have one's seeds from "Bartram's garden".

Succeeding Bartram and Marshall, our neighborhood was fortunate in possessing two intelligent and most worthy gardeners from England. David Landreth, who had been educated as a nurseryman, settled at Philadelphia in 1784; he was shortly after joined by his brother Cuthbert. The two, with such slender means as they could command, ultimately established themselves in business, uniting for a time to their own fond pursuit (as a resource to meet present wants) the culture of rare culiwhich the Philadelphia market now sustains - unrivalled by any city in the Union. Gradually following the bent of their excellent taste and cultivated minds, they added commercial green-houses, which were the delight of the writer's youthful days. Rare plants - then how rare! - found their way, by their enterprise, to our borders, and a business in these articles was commenced which has grown to be one of national importance, and is especially successful here. I allude to the commerce in Camellias, Roses, and rarer flowering plants, no less than trees. The Landreth Nurseries have had an enviable celebrity, of which the descendants of these honorable dealers may well be proud. I can recollect when all the intelligence of Philadelphia resorted there to improve their taste and increase their collections.

The whole town went out for many seasons to see the blooming of the first Multiflora Rose, the collection of Azaleas, and other valued novelties. The Maclura for a hedge plant was first introduced here, from seed brought by Lewis & Clark. The original fruit-bearing tree was till lately a source of millions of seeds; but, having attained the size of a large Apple tree, it is now bowed down by many a blast, but in green old age. Ornamental Magnolias, especially the conspicua grafted on the acuminata, eminated extensively from this garden, to which the most beautiful specimens of many other species of trees and shrubs may be traced. Calm and industrious and truly honest in the pursuit of their interesting business, these gentlemen lived long in the enjoyment of their just reward, and the writer is mistaken in their characters, if their career and intelligence was in the least inferior in importance to that of Bartram. In a rather different line, and with a better home market, they took up the ball where Bartram dropped it, kept it in motion, and popularized the pursuit, reaping a just recompense.

More fortunate than Bartram, a descendant, the son of David, carried on their ever-increasing business, till competition in green-house and tree culture' had so reduced the profits as to give less return than formerly. The old gentlemen had, however, not neglected to supply a growing demand for vegetable seeds, to the cultivation of which they appropriated some ten, and then twenty, and afterwards the enormous amount of thirty-five acres! "Landreth's seeds" acquired a great and growing reputation; the demand soon exceeded the supply, and gradually the tree and green-house establishment had to give place to the approach of the city. The mansion house has been converted to the uses of a public school, called after the owners. The great stock of ornamental trees and shrubbery was dispersed by auction, giving a supply eagerly embraced by purchasers, which has done much to embellish our neighborhood. Laurel Hill Cemetery, now quite an arboricultural wonder for its variety and beauty of planting, as well as hundreds of other beautiful places, owes much of its ornamentation to this source. We must not omit the origin, at these great nurseries, of the Camellia Landrethii, an exceedingly valuable variety, which is destined to carry down to posterity the name so much respected among us.

The nursery and garden grounds soon grew too small for the ever-increasing seed business; other land was procured in the neighborhood, till the vexation and difficulty home and abroad, and Mr. David Landreth, the younger, who now became the sole proprietor* of the business, determined to concentrate the whole of the processes in one shot. A most fortunate location in every respect presented, and Bloomsdale, a magnificent farm of about 250 acres, was purchased, twenty miles above Philadelphia, and near the town of Bristol, having now a front on the Delaware river of more than a mile. The ground was every way adapted to the object in view. Of suitable soil, level, and in a high state of cultivation, it was immediately turned to successful account. The fences were removed, the fine old family mansion greatly enlarged and made everything that a country gentleman could desire, with a lawn planted with all the new and old valuable trees in vogue, each with space sufficient to develop its beauties, and the seed business in America took at once a position commensurate with its value and importance.
