Ogden wrote for answer that he could not make the necessary
arrangements. The battle of Bunker's Hill (on the 16th of June, 1775)
followed in rapid succession; whereupon he started for Elizabethtown,
New-Jersey, to meet Ogden, and aid him in preparations for the journey
to Cambridge, where the American army was encamped.

Burr had been reading those portions of history which detailed the
