Andre' was, accordingly, dispatched in the Vulttire, sloop of war, to hold a personal conference with General Arnold. The Vulture ascended the Hudson river on the 20th, as far as Teller's Point, and came to anchor at the mouth of the Haverstraw bay. Here Andr£ eagerly awaited some opportunity to acquaint Arnold with his arrival. An occasion for so doing presented itself the next day. A white flag was displayed at a See Barnuni's Spy Unmasked.

THE TOWN OK GREENBURGH.

Teller's Point by some of the country people, which, being interpreted as they wished, the captain of the Vulture sent off a boat with a Hag, which was fired upon as soon as it approached the shore. This gave Andre the opportunity he desired, as it was a proper subject for a remonstrance to the commanding officer; and a flag with a letter was accordingly dispatched. The letter was dated on the 21st Sept.; it was in the handwriting of Andre, signed by the captain of the vessel, and countersigned "John Anderson." (Andre's assumed name.) This Hag was sent to Verplank's Point. Arnold arrived just as the boat returned to the Vulture. The letter was handed to him, and, of course, fully understood ; thereupon he hastened to prepare Smith for a visit to the enemy's vessel on the approaching night. Crossing from Verplank's to Stony Point he made all the requisite arrangements respecting the boat that Smith would want, and then proceeded to his quarters to remove the difficulty which had occurred respecting boatmen. The guard boats had received orders not to stop Smith, and he also possessed the countersign for the next night, which was the word " Congress." In tlie morning Smith brought his tenant -- Samuel Colquhoun, to a conference with Arnold, who requested him to accompany his landlord on a visit that night to the Vulture" The man at first refused, but at last consented to go with his brother, Joseph Colquhoun, and Smith.
