Standing on high ground and commanding broad views both up and down the stream, the house is of truly baronial mien and Georgian character. Two flanking outbuildings, two and a half stories high, hip-roofed and dormered, some forty feet from each end of the main house and corresponding with it in character and construction, provide the[73] servants' quarters and various domestic offices. Beyond the circle formed by the drive on the east or entrance front of the house and at some distance to either side are two barns. Thus the house becomes the central feature in a strikingly picturesque group of buildings having all the manorial impressiveness of the old Virginia mansions along the James River.
The main house rises two and a half stories above a high foundation of hewn stone with iron-barred basement windows set in stone frames. It is of massive rubble-stone masonry, coated with yellowish-gray rough-cast and having heavy quoined corners of red brick, also a horizontal belt of the same material at the second-floor level, the keyed lintels of the large ranging windows, however, being of faced stone.
Above a heavy cornice with prominent modillions springs the hipped roof, pierced on both sides by two handsome dormers and surmounted by a long, beautifully balustraded belvedere. Two great brick chimney stacks, one at each end of the building, with four arched openings near the top, lend an aspect of added dignity and solidity. The principal feature of the façade on both the east and west or river front is the slightly projecting central portion with its quoined corners, surmounting corniced pediment springing from the eaves, ornate Palladian windows in the second story and superb pedimental doorway in harmony with the pedimental motive[74] above. Although the detail is heavy, and free use has been made of the orders, the work is American Georgian at its best and altogether admirable. The doorways of the two sides are similar but not the same, and a comparison, as found in another chapter, is most interesting.
Within, a broad hall extends entirely through the house from one front to the other, as likewise does a spacious drawing-room on the north side with an elaborate chimney piece in the middle of the outside wall. The dining room occupies the west front, and back of it, in an L extension from the hall, a handsome staircase with gracefully turned balustrade leads to the bedrooms on the second floor. Throughout the interior the wood finish is worthy of the exterior trim. Beautifully tooled cornices, graceful pilasters, nicely molded door and window casings, heavy pedimental doorheads,—all are of excellent design and more carefully wrought than in average Colonial work. Finest of all, perhaps, is a chamber on the second floor overlooking the river that must, according to the very nature of things, have been the boudoir of the mistress of Mount Pleasant. The architectural treatment of the fireplace end of this room, with exquisite carving above the overmantel panel and above the closet doors at each side, is greatly admired by all who see it.
The erection of Mount Pleasant was begun late in 1761 by John Macpherson, a sea captain of[75] Clunie, Scotland, who amassed a fortune and lost an arm in the adventurous practice of privateering. Here he lived in manorial splendor, entertaining the most eminent personages of the day with munificent hospitality and employing himself with numerous ingenious inventions, notably a practical device for moving brick and stone houses intact. He wrote on moral philosophy, lectured on astronomy and published the first city directory in 1785, a unique volume giving the names in direct house-to-house sequence and having such notations as, "I won't tell you", "What you please", and "Cross woman" against street numbers where he found the occupants suspicious or unresponsive to his queries.
Meeting reverses in some of his financial affairs and longing for further adventures at sea, Macpherson sought the chief command of the American Navy at the outbreak of the Revolution. This being denied him he leased Mount Pleasant to Don Juan de Merailles, the Spanish ambassador. But to be near General Washington, Merailles had to remove to Morristown and there he soon died.
In the spring of 1779 Macpherson sold Mount Pleasant to General Benedict Arnold, of unhappy memory, whose remarkable and traitorous career is known to every American. Arnold had been placed in command of Philadelphia by Washington, following its evacuation by the British, and in acquiring the most palatial countryseat in the vicinity[76] he gratified his fondness for display and apparently saw in it a means of retaining or increasing his influence and power. It was his marriage gift to his bride, Peggy Shippen, the daughter of Edward Shippen, a moderate Loyalist, who eventually became reconciled to the new order and was chief justice of the State from 1799 to 1805. At Mount Pleasant Arnold and his wife remained for more than a year, living extravagantly and entertaining lavishly. Arnold's financial embarrassments and bitter contentions with persistent enemies became ever more deeply involved. Here in bitterness, and not without some provocation, he conceived the dastardly plan of obtaining from Washington command of West Point, the key to the Hudson River Valley, in order that he might betray it to the British.
Following the discovery of the plot and Arnold's flight to the British lines, his property was confiscated, and Mount Pleasant was leased for a short period to Baron von Steuben, after which it passed through several hands to General Jonathan Williams, of Boston, in whose family the place remained until the middle of the nineteenth century, when it was acquired by the city as a part of Fairmount Park.
At Number 5442 Germantown Avenue, standing directly on the sidewalk as was often the case, and with a beautiful box-bordered garden of old-fashioned flowers about one hundred by four hundred feet along the south end, is one of the most interesting[77] old plastered houses in Philadelphia. Well known in history, it is no less notable architecturally. In general arrangement it differs little from numerous other gable-roof structures of the vicinity, two and a half stories high with chimneys at each end and handsome pedimental dormers with round-topped windows between. It is in the excellent detail and nice proportion of the wood trim, both without and within, that this house excels. Interest focuses upon the deeply recessed doorway with its sturdy Tuscan columns and pediment, and the great, attractively paneled door. The fenestration is admirable with twenty-four-paned windows set in handsome frames with architrave casings and beautifully molded sills, the lower windows having shutters and the upper ones blinds. A notable feature is the heavy cornice with large modillions, and beneath a relatively fine-scale, double denticulated molding or Grecian fret.
Within, a wide hall extends through the middle of the house, widening at the back where a handsome winding staircase with landings ascends to the floor above. Opposite the staircase is a breakfast room overlooking the garden. The parlor and dining room on opposite sides of the hall, the bedrooms above and also the halls all have beautifully paneled wainscots. There are handsome chimney pieces in each room with dark Pennsylvania marble facings about the fireplaces and ornamental panels[78] so nicely made that no joints are visible. Throughout the house the woodwork is of unusual beauty and unexcelled in workmanship.
