This picturesque object is seen to great effect by the passenger in the evening boat from New York to Newburgh. Leaving the city at five in the summer afternoon, she makes the intervening forty miles between that hour and twilight; and while the last tints of the sunset are still in the sky, the stars just beginning to twinkle through the glow of the west, the bright light of this lofty beacon rises up over the prow of the boat, shining apparently on the very face of the new-starred heaven. As he approaches, across the smooth and still purpled mirror of the silent river is drawn a long and slender line of light, broken at the foot of the beacon by the mild shrubbery of the rock on which it stands; and as he rounds the point, and passes it, the light brightens and looks clearer against the darker sky of the east, while the same cheering line of reflection follows him on his way, and is lost to sight as he disappears among the mountains. The waters of the river at this point were the scene of the brief and tragic drama enacted so fatally by poor André. Four or five miles below stands Smith’s house, where he had his principal interview with Arnold, and where the latter communicated to him his plans for the delivery of West Point into the hands of the English, and gave him the fatal papers which proved his ruin. At Smith’s house Mrs. Arnold passed a night, on her way to join her husband at West Point, soon after he had taken command. The sufferings of this lady have excited the sympathy of the world, as the first paroxysms of her distress moved the kind but firm heart of Washington. There seems to have arisen a doubt, however, whether her long and well-known correspondence with André had not so far undermined her patriotism, that she was rather inclined to further than impede the treason of Arnold; and consequently could have suffered but little after Washington generously made every arrangement for her to follow him. In the “Life of Aaron Burr,” lately published, are some statements which seem authentic on the subject. It is well known that Washington found Mrs. Arnold apparently frantic with distress at the communication her husband had made to her the moment before his flight. Lafayette, and the other officers in the suite of the commander-in-chief, were alive with the most poignant sympathy; and a passport was given her by Washington, with which she immediately left West Point to join Arnold in New York. On her way she stopped at the house of Mrs. Prevost, the wife of a British officer, who subsequently married Colonel Burr. Here “the frantic scenes of West Point were renewed,” says the narrative of Burr’s biographer, “and continued so long as strangers were present. As soon as she and Mrs. Prevost were left alone, however, Mrs. Arnold became tranquillized, and assured Mrs. Prevost that she was heartily sick of the theatrics she was exhibiting. She stated that she had corresponded
