OUR series of visits to Country Places has been postponed for the sake of variety, and in obedience to the demands of correspondents. Princeton neighborhood occupied our last notice, but was left incomplete.

Woodlavm, the seat of Richard Stockton Field, Esq., presents so many features of beauty and good planting, that we return to it once more. Its grand feature is the beauty and symmetry of the evergreens, planted comparatively only yesterday, and really only twelve to fourteen years ago. The White Pines are thirty to thirty-five feet high, with proportionate breadth, though two of them have assumed the precise shape of the old Lombardy Poplar, growing into a cone-like form which is entirely unusual, and for which no apparent cause can be assigned.

But the beauty is by no means confined to the White Pines. Mr. Field has assembled such a large family of evergreens as we rarely meet with, and he understands their wants so entirely that all seem grateful inmates; the rarer kinds hold a prominent place; the generally naked Thuja pendula, or Japan Weeping Arbor Vitae, here has really a dense and admirable growth. In juxtaposition with this weeping Asiatic, is the Washingtonia gigantea, the giant tree of California; (in the open centre of one of these trees, in its native haunt, it is practicable to drive a Conestoga wagon.) We opine that this tree will be one of the most rapid growers of all our hardy evergreens, and are happy to say many specimens inspected this spring indicate its adaptation to our northern climate.

Mr. Field's Abies Frazerii is about twenty-five feet high, round-headed, of a beautiful silvery green, and an exceedingly rare specimen. It is very conspicuous among a cluster of an excellent variety of some of our native red cedar; it requires a nice eye to detect some varieties of this neglected native from the high-priced and incense bearing Juniper of Spain.

The dense-headed Austrian black pine makes a prominent feature amongst other pyramidal trees. The Cedar of Lebanon has always been regarded as one of the stubborn foreigners, but here it grows with almost the rapidity of a White Willow; in about fifteen years it has attained to the height of thirty feet, and stood all but unscathed during two late hard winters. One of the causes we ascertained to be the nature of the soil in which it grows; this is a prominent ridge of a yellowish loam on a subsoil of gravel peculiarly favorable to such evergreens.

Having in a previous article noticed the principal trees of rarity of beauty, we cannot repeat, but it would be unpardonable if we overlooked, (we cannot forget), a plant of Juniperus squamata, the most interesting and curious specimen we have ever encountered. The lower branches form a basin in vigorous growth, with an upright center of about five feet in the exact form of a fountain - an actual evergreen fountain situated in a recess formed by a wing of the mansion. This unique plant would amply repay a connoisseur for a visit to this noble place.

We have another feature in the outline that cannot be overlooked; the useful has been brought into happy juxtaposition. Pear trees of distinct forms, showing the judgment and care of the proprietor and his assistants, yield abundance of fruit for the home and its visitors. You can from the roads discern the best kinds, and point out the peculiar conical form of the Seckel, the tapering cone-shaped Lawrence, the pyramidal Urbaniste, the large spreading arms of the Duchesse, and the poplar form of the Buffum. This pear tree in the absence of the unwarrantably discarded Lombardy should not be overlooked by the planter who would introduce a useful conical object. It is hinted that the finest Buffum is to give way for the contemplated new pinetum, but that one specimen we hope may be spared.

Princeton and its vicinity contains many beautiful places, and is historically interesting from its colleges, and the worthies of note who have successively filled its learned chairs.

Morven, the property of Commodore Stockton, is a fine old place of the times of the Revolution, having been in the family ever since the first settlement of the State. It was a part of a tract of land purchased of William Penn by the Commodore's ancestor more than a century and a half ago, and has now some fine Elms planted by the signer of the Declaration of Independence, Richard Stockton. A row of very large Catalpas, extending more than a quarter of a mile, were in full bloom at our late visit, presenting a magnificent appearance. The proprietor resides alternately in Philadelphia and at the sea-side. Morven has consequently been somewhat neglected of late, and it shows the effects.

Prospect, late the residence of Thomas F. Potter, and now that of his widow, is on a fine site overlooking the county of Monmouth; the view is so extensive that it is easy to fancy one's self in sight of the sea, which in fact is not very distant. Mr. Potter died soon after the completion of the mansion, which in all its details exhibits the good taste of its architect, Notman, who has introduced a conservatory attached to the house, and a fine grapery now very productive, that adds material beauty to the winter scene; the grounds possess great capabilities.

Mr. Senator Thomson's residence is almost in the town, consisting of about four acres, well planted and giving many fine effects. A visit to it convinces the eye that it possesses the requisites of a country seat. There is a fine collection of evergreens, a grapery and green house, and everything is kept in the finest order. Mr. James Potter has a place of about the same size; it is also distinguished for its fine evergreens, and has a fine grapery. Here we would remark on the beauty and gentility which even a few evergreens give to a rural scene; they warm up everything near; without them, dreariness comes over the eye and the spirits.

The places of Richard Stockton, and John P. Stockton, (the latter now our minister to Rome,) sons of the Commodore, are comparatively new, but are largely planted, and their trees are* growing finely. Notman's taste is here again apparent.

Of Princeton College, we could say much, but may only note a few of its celebrated Presidents. The first was Jonathan Dickinson, whose appointment was made in 1746, and from whom descended our townsman, the late John Sergeant Aaron Burr succeeded Dickinson, having married the daughter of the celebrated Jonathan Edwards; he left a son, the too celebrated Aaron Burr, who in spite of his illustrious parentage, became what we know him to have been. The residence of President Burr is still extant; and the murderer of Hamilton rests near by.

Jonathan Edwards succeeded his son-in-law as President. His reputation is world-wide, and needs no comment here. Samuel Davies, Samuel Finley, Dr. John Witherspoon, Dr. Samuel Stanhope Smith, Dr. Ashbel Green, Dr. James Clernahan, and now Dr. John Maclean, have each and all added to the fame of this celebrated seat of learning, which numbers on its roll of alumni very many eminent scholars, divines, lawyers, and politicians, and is still in the full career of its usefulness.
