EMERALD AUXILIARY SCREW STEAMER.

(From the Steam Navigation Gazette.)
We have much pleasure in giving our readers the extract
from a letter by Captain Prichard to Lieut. Sarsfield, R.N"
the intelligent Marine Manager of the City of Dublin
Company :

" Belfast, Oct. 15, 1816.
This is to inform you of our safe arrival in this port
from London, after a passage of four days and three hours.
The first thirty hours we had a strong breeze from the
west ; after, for five or six hours, the wind was flying
about to the south-west, until we got to the Isle of Wight.-
We then got the wind to the northward, which carried us
to the Lizards, after this little or no wind ; but at tee,
that evening it came on like a hurricane from the westward
to the north-west and round to the southward, and thee,
came a•hea.i. There were two screw-boats which bad
left London, one twenty-tour hours before us, for Lira"
crick, and we passed her off the North Forelands. The
other left thirty hours before us—we passed her off the,
Isle of Wight. The Pearl—(built by Ditchbourne and
Mare,—engines by Maudalay and Field).—left the same
day from Southampton that we left Loudon; we spoke
her off the Land's End, and arrived here seven hours'
before her. Close haul'd we beat them the most; we
went to windward more than any we tried with ; we acted
well both with the wind a-head and fair, and did net
labour in the least—were quite dry, and ran much better
than I expected."
We wish particularly to draw attention to this account
in consequence of the Emerald being the first of several
vessels of various sizes, built at Liverpoql, with auxiliari
steam power, having Mr. Grantham's patent arrange'
ments, by which all spur wheels and multiplying gear aaro
removed, and the engines applied direct to the screw !,hf:
as in paddle-Wheel vessel
steamers : thus obviating one
greatest objections to the screw propeller. The
t ~xfact
was also modelled by Mr. Grantham. Besid ! t'
of the Emerald's great superiority over the,other,_.•. three,

screw vessels, as stated in. Captain Pritchard's tette', ...-
would notice a still more important circumstance.

of the same distance. On the other hand, the Emerald
can take from 200 to 300 tons cargo, burns about 25 tons
of coals, and has cost under £9OOO.

We shall wait with much interest for the result of the
Sarah Sands, a vessel of 1000 tons, now building under
Mr. Grantham's directions, and fitted. on the same prin-
ciple.
