STEAMING ON CANALS.

We noticed few weeks siDce. thai model Of
steam boat with the prupcllng powrr on the
pncple Of seuiling boat had been brought to tbs
county from England, by Mr.. Strickland and also
spoke Of ITS Application TO cdual boats, aud perhaps
To our packet ships. II -, perhaps, premature IL
speculate on the great revolution which the success
OF the experiments made in Eng land. and the
scquent adoption OF steam power ON the canals,
would occasion 10 canal navigation ~ tins country
but ifom the following nuuce that We hnd T.. the
Manchester Guardian Ne presume that the annex
ed description oil an experiment made by the Novel
w. ~ she Is called, through the canals between
London aud Manchester, At the rate OF about seven
miles an hour, will be interesting to many Of our
readers
An IRON steamboat, built by Mr. John Famed,
Of North BuLenhead, tunder the inspection OF Mr..

and fitted with the scullng propeers, was launched
on The 7th inst. She Is al present waiting for her
boilers and IT Is expected will be tied the Mcrsey
IA the course oil next week. She Is intended to be
worked rs q steam tug. 10 tow shlps upon the Dra

boat httcd with species OF paddles already de
scIbcd. but perhaps better known Is " Elcsons p,o-
pellet" IN substitution Of the side paddles. Of the
old steamrts-whch are constructed so rs to prnpel
without raising surge injurious 10 canal banks

ease aud salcty-oblceis hitherto unattaned, and
deemed inptaelicablc. The man PECULIARLY Of tbs
invention IS the construction OF the paddle rs
secure an action resembling that OF fish tail or Of
perpetual sculIIng through the water. Thr differ
ence between the operation of the ptopelicrs and
that the fish double scull IS that Instead OF the
lorce being alternate from side TO side the propclcfs
strokes upon the water simultaneous. We be
fore explained the construction pt the paddle boards
aud the fact of their revolving IN opposite directions
This Is effected by the wheels rlue beng fixed one
10 a hollow shaft and the other 10 u solid shaft re
,olvIne within the hollow one that, although
they move III opposite directions they turn upon the
same centre, each opponent puddle board striking
the water at the same time. The power from the
engine Is communicated by a c1ank at the solid
sLat cog-wheel attached to the crank 81 aft works

obtained by gearing aud endless chain As these
propcllers work with the greatest effect when sub
MERGED, no waste OF power IS IncuIcd, and no sha
