During the afternoon OF the same day .

the end Of it log Of timber, and after having
been towcd with mile aud half OF cable, was
coiled in again with success.
On "Wednesday, about half way, between the
Lands End and the coast Of Ireland. another
length was run out at the rate Of six and q |
half knots per hour, and subsequently hauled
in. The Agamemnon then stecred for Cork,
and reached Queenstown Harbor at o'clock
on Thursday morning, all on board being more
than ever satisfied at the success Of the enter
prise. s s
Some highly successful experiments were also
at the same time performed with an electrical
log, invented BY Mr.. Chas Bright for the pur-
pose Of continuously ascertaining with accuracy
the rate At which the ships are sailing, and
thereby OF enabling him to give corresponding
directions As 70 the rate Of paying the cable, 20

strain being put upon it. The log is suspended
in the sea from the ships quarter by fine car
ryng within tia wire insulated by gutia pcrcha, |
which Is in connected with battery and electro
magnet contained within an indicating instru--
ment on deck. This Is so arranged that, at
each revolution Of the wheel below, an electric
current is broken, and, by the DETECTION of
magnet which forms part Of the circuit, step
by step movement is communicated 10 a regis. |
