A few rods above the residence of Professor Longfellow is the house in which the Brunswick general, the Baron Riedesel, and his family were quartered, during the stay of the captive army of Burgoyne in the vicinity of Boston. I was not aware when I visited Cambridge, that the old mansion was still in existence; but, through the kindness of Mr. Longfellow, I am able to present the features of its southern front, with a description. In style it is very much like that of Washington's head-quarters, and the general appearance of the grounds around is similar. It is shaded by noble linden-trees, and adorned with shrubbery, presenting to the eye all the attractions noticed by the Baroness of Riedesel in her charming letters.[8] Upon a window-pane on the north side of the house may be seen the undoubted autograph of that accomplished woman, inscribed with a diamond point. It is an interesting memento, and is preserved with great care. The annexed is a facsimile of it.

It stands upon Washington-street, near the westerly corner of the Common, and is distinguished by the circumstance that, beneath its broad shadow, General Washington first drew his sword as commander-in-chief of the Continental army, on the 3d of July, 1775. Thin lines of clouds, glowing in the light of the setting sun like bars of gold, streaked the western sky, and so prolonged the twilight by reflection, that I had ample time to finish my drawing before the night shadows dimmed the paper.
