Maillefert and Captain Raaslof have renewed
operations against the famous :. Pot Rock" at
Hell Gate, by direction of the Government and
under the superintendent Of Brevet Major D.
Fraser, U S. A; and the results, so far as
known, are as gratifying as before 1t will be
remembered that the first intention was to re-
duce Pot Rock to 20 feet from the surface (meau
low tide). This has been accomplished. and
now the Government, approaching the impor-
tance Of rendering the Gate safe for the passage
Of ships of the navy, and with them all other
vessels, has determined to reduce it TO a feet
which Herculean task will in all probability be
completed in few days. Some idea Of the
magnitude Of the undertaking may be had from

to the depth required has been reduced one.
