The earlier American nurseries were few in number, and, compared with some now existing, of quite limited extent,—though equal, perhaps, in proportion to population. The first of which there is any record, and probably the earliest established, was that of John Bartram, near Philadelphia, about the year 1730. Here were congregated many of the prominent native plants and trees, preparatory to exportation to Europe,—also the fruits and plants of the other hemisphere, obtained in exchange for American productions. The specimen trees planted by the elder Bartram and his descendants still adorn the grounds, classic to the botanist and the lover of Nature: long may they stand, living memorials of generations passed away, our earliest evidence of a taste for horticulture!

The next nursery in the order of date is that of Prince, in Flushing, New York, established, we believe, prior to the Revolution, and continued by the family to the present day. Flushing has become a centre in the nursery-trade, and many acres thereabout are covered with young trees intended for transplantation. A stroll round the village would lead one to suppose the chief interest of the inhabitants was bound up in the nursery-business, as is that of Lynn in shoes, and of Lowell in cotton goods. Prominent among the Flushing nurseries are those of Parsons, which, though of comparatively recent origin, abound in rich treasures.

The nurseries of the brothers David and Cuthbert Landreth appear to have been the third in the order of succession. They were established at Philadelphia shortly after the Revolution, and within the limits of the city. The increase of population and their expanding trade caused a removal to another and more ample field of culture, which, for nearly half a century, was the resort of most people of taste who visited Philadelphia.

Nurseries are now found everywhere. The Far West has some which count the young trees by millions, and fruit-trees of single kinds by the hundred thousand. The Hoveys, of Boston, have long been prominent, not only as nurserymen, but as writers on horticulture. Elwanger and Barry, of Rochester, New York, have a large breadth of land, we forbear to state our impression of the number of acres, covered by nursery-stock. Professional florists also have multiplied to an unlimited extent, exhibiting the growth of refining taste. Plants suited to window-culture, and bouquets of choice flowers, are sold on street-corners, and carried from door to door. Cameilias, of which we recollect single flowers having been sold at a dollar, can now be purchased at fifty cents the plant.

It might be curious, in reference to this subject of horticulture, to institute an inquiry as to cause and effect. Have the increased means of gratifying taste expanded it, or has taste rapidly developed created the means of supply? Doubtless there has been reaction from both directions, each operating on the other. One striking exhibition of pure taste among us is the formation of picturesque arboretums, especially of terebinthinate trees, and others allied to the Coniferae. This taste, so diligently cultivated in England, has found zealous worshippers among us, and some admirable collections have been formed. The cemetery of Laurel Hill, at Philadelphia, under the critical eye and taste of the proprietor, Mr. John Jay Smith, that of Mount Auburn, in Cambridge, of Greenwood, New York, and the cemetery in Cincinnati, have afforded fine specimens of rare trees, though, from the nature of their purposes, picturesque effect could not be reached, except so far as aided by irregularity of surface. And here we would remark, in connection with this subject, that one regulation of the Cincinnati cemetery is worthy of imitation. No arbitrary railings or ill-kept hedges bound the individual lots; all is open, and the visitor, as he drives through the grounds, is charmed by the effect,—a park studded with monuments: the social distinctions, which, perhaps, necessarily separated in life, have disappeared in death.

In connection with landscape-gardening, one American name stands conspicuous,—the name of one who, if not, in point of time, the first teacher of the art in this country, has at least done more than any other to direct attention to it,—to exhibit defects, suggest improvements, create beauties, and invest his subject with such a charm and interest as to captivate many minds which might otherwise have been long insensible to the dormant beauty within their reach, or that which they themselves had the power to produce: we refer, of course, to the late Andrew J. Downing. With naturally fine artistic perceptions, his original occupation of a nurseryman gave direction to his subsequent pursuits. Under different circumstances, his taste might, perhaps, have been turned to painting, sculpture, or architecture: indeed, to the last he paid no inconsiderable attention; and as the result, many a rural homestead, which might otherwise have been a bleak house, is conspicuous as the abode of taste and elegance.

Among the prominent private arboretums in our country may be mentioned that of Mr. Sargent at Wodeneshe. Mr. Sargent, as may be seen by his supplement to Downing's "Landscape-Gardening," is an enthusiast in the culture of conifers; he is reputed to have made liberal importations, and the results of his attempts at acclimation, given to the public, have aided others in like endeavors. Judge Field, of Princeton, New Jersey, has a pinetum of much value; some of his specimens are of rare excellence. He, also, has been a diligent importer.

Though our sketch of the present state of horticulture among us is quite imperfect, affording but an indistinct glimpse of the ample field which invites our view, it would scarcely be pardonable, were we to overlook a branch of rural industry in which horticultural success is interested, and without which the practical pleasures and family-comfort of rural homes would be greatly abridged. We refer to garden-seed culture. It may be that the purchaser of a paper of seed for the kitchen-garden seldom stops to consider the minute care which has been required to secure its purity; most probably, in many cases, he makes the purchase as though it were the mere product of mechanical skill, which, after the machinery is perfected, and the steam-engine has been set in motion, turns out the finished article, of use or ornament, with scarcely an effort of mind to direct its movements. Not so in the production of seeds: many are the hours of watchful care to be bestowed upon it, and stern and unyielding are its demands on the skilled eye and the untiring hand. It is because in some cases the eye is not skilled, and the hand often tires, that so many seeds of more than doubtful worth are imposed upon the market, filling the village and cross-road shops with the germs of disappointment. The history of the seed-culture in the United States is not without interest to those who, like many readers of the "Atlantic," reside in the quiet country; to every family thus situated the certainty of obtaining seeds of trustworthy quality—certain to vegetate, and sure to prove true to name—is of more importance than can be appreciated by those who rely upon the city-market, and have at all times and seasons ample supplies of vegetables within easy reach. On looking round for some individual establishment which we may use as the representative of this branch of industry, we naturally turn to Bloomsdale, as the most prominent and widest-known of seed-farms; and if the reader will join us in a trip thither, we shall be pleased with his company, and perchance he may not wholly regret the time occupied in the excursion. The period we shall choose for the visit is the close of the month of June.

On a bright day we take our seats in the cars at Jersey City, provided with the talisman to insure an attentive reception. Onward we whirl through fertile fields and smiling villages; Newark, Brunswick, Princeton, are successively passed; shortly we reach the Delaware at Trenton; a run of a few miles through Penn's Manor, the garden-spot of the Proprietary Governor, brings us to Bristol, the station from which we most readily reach our destination. As we approach the grounds from the front, a prominent object meets the eye, a noble white pine of gigantic proportions, somewhat the worse for many a winter's storm, but which still stands in all its majestic grandeur, as it has stood whilst generations have come and passed away. On entering the premises, we find ourselves in the midst of a lawn of ten acres in the English style. To enumerate the various trees, in groups or single specimens, which most invite our notice, would interfere with the main object of our visit. We have come for a special purpose, and we can only allude to a very few of the species to which our attention may be supposed to be directed. A white spruce, in rich luxuriance, measuring, as the branches trail upon the sward, upwards of sixty feet in circumference; the Himalayan white pine, with its deep fringe-like foliage, twenty-five feet in height; the Cephalonian fir, with leaves as pungent as an Auricaria, twenty feet high, and many specimens of the same kind of nearly equal magnitude; yews, of more than half a century's growth; a purple beech, of thirty feet in height, its branches as many in circumference, contrasting with the green around; numerous specimens of balm of Gilead, silver firs, and Norway spruces, unsurpassed in beauty of form, the last presenting every variety of habit in which it delights to sport: these are some of the gems of the lawn. But we must hurry onward to the practical business in view.
