SUCCESSFUL WORKING OF TIE MUSHROOM -
A HOLE DRILLED IN FRYING PAN-sIX FEET

In THE TRIBUNE of Tuesday a brief descrip-
ton was given Of Mr.. Sidney f. Shelburne's novel ma

the last three days In the swift currents Of Hell Gate
must be considered as eminently encouraging As was
ntmaed previous article the pipe used to convey
the exhaust steam from the engines nclosed In and sunk
with the mushroom" was found too flexible and too
small larger and Grmer had 10 be procured from
Boston, causing delay which prevented any trials Of
the drill from being made on Tuesday. Yesterday
the new pipe was severely tested III very swift current
and found to work satisfactorily. Assuming the ma
chnery OF the drill be in working order the first prob
lem is 10 keep the floating derrick stationary wme the
