The Lincoln [First New York] Cavalry, Col. ANDREW T. McREYNOLDS, took their departure yesterday for Washington, going by the Camden and Amboy route. The rumor, an unauthorized one, that the regiment was to have a presentation of regimental colors by Mrs. President LINCOLN, raised the hopes of the men somewhat, but they finally concluded to wait for the realization of their hopes until they reach Washington...
