John A. RoabllDg, engineer Of the New York Bridge
Company, presented on Saturday last at q meeting Of
the Executive Committee his report bearing date Sep

Of construction Of the BRIDGE the principles OF tie

company conhned IN the location OF its terminus
the New York side to latitude ranging from Chatham
square along the line Of Chatham street 10 the inter
section OF Nassau and Chatham streets Ths provision
renders but two points OF termination feasible

opposite the City Han Park. In the vicinity OF Printing
House square, On the Brooklyn side the bridge will
terminate near the Fulton ferry third route termi-
mating at the Bowery and Canal street. Is supposed by
way Of comparison; but that terminating Chatham
square Is decided the shortest by distance or elk

would be lessened py hundred and twenty feet In
discussing the apprasement Of the property which will
DO occupied he concludes that the Chatham square ter
