Mr. Tilden had already become interested in a small way in the establishment of the first balance dock ever provided for the New York harbor. His friends, O'Sullivan, Waterbury, and Secor, were also among the number interested with him. The following contract shows the nature and extent of Mr. O'Sullivan's interest. The venture did not prove very profitable to them, nor to have received much attention from Mr. Tilden.
