The superintendent, W. c. Kingsley. and the Chief
Engineer, W. A. ROebing presented their reports OF
operations for the year. The Engineers report gives
detailed account OF the sinking OF the great casson for
the east tower showing minutely the engineering pro-
cesses by which solid timber platform, IA feet In
length by &c feet in width and feet I'm thickness was
gradually sunk to depth of As feet below the water ne
great part OF the distance being accomplished by
cavation through hard bed of clay and gravel abound
ing I'm great powders which evidently had been origin
ally swept down from the Palisades the Hudson Tho
cassOn is the largest that has been SUNK though
others have been sunk deeper. The lower part OF the
cass0n constructed as to afford large chamber
deep enough for to walk about in and protected at
the sides by a rim which terminates in a sharp edge
shod with iron. The workmen occupied this damber in
excavatng the rver-bed, being secured against any In
ward rush Of water by the filling OF the space With COM
pressed air. The difficulties and dangers Of til, work
are best set forth in the following extract FROM the
