state .^ovci'iiiTicnt, wlience they infer that further investigation may 
show tiiis commufiication to be practicable. 
In ext'cutioii of the orders of the Secretary of War, requiring a co- 
operation with the canal comnussioners of the state of Pennsylvania, 
the boaid examined the whole route of the {)roposed canal, from the 
Allegany to the Schuylkill. From observations made by the board 
along this line, and from surveys, and levellings, since made by the 
Pennsylvania commissioners, the board are inclined to believe in the 
possibility of this work; but they think that further investigations are 
necessary to tlie definitive settlement of this question. 
The co-operation of the board, with the commissioners of the state 
of New Jersey, resulted in a strong conviction of the practicability 
of a canal communication between the Delaware, and the Rariton, 
by Icadijig the water of the former, from about twenty-six miles abov 
the city of Trenton, to the summit ground between Trenton and 
Brunswick; and that the abundance of the water of the Delaware 
will supply a canal, of dimensions adapted to the vessels navigating 
the great rivers and bays of the seacoast. The board are, however, 
of opinion, that, previous to fixing the exact route of the canal, lines 
should be rim from the vicinity of Bordentown, across the summit, 
to the lowest point on the Rariton, to which a canal can, with due 
economy, be extended, with a view to avoid as much of the difficult 
tide navigation of the two rivers as possible. 
The board has the satisfaction to acknowledge the zeal, persever- 
ance, and ability, with which all the officers of the two corps of en- 
gineers, and other gentlemen attached to the service, have fulfilled 
their duties, to tiie extent which the time, and the season of the year 
permitted. The unfinished parts of their instructions comprehend 
the eastern section of the Ohio, and Chesapeake canal, from Cum^ 
borland to tide, some lines on the summit, stnd the whole western 
section. ,
