we have noticed the result OF the first voyage of IN,
sarah Sands large packet chip built OF iron and trad
ing between Liverpool aud New York We have since
then seen the plans Of this vessel her engines and
tho whole subject appears ~ interesting that wa

support OF . Government contract for carving the

Sarah sands II the rHt instance believe In which
the question has been fairly teetod and We ara NOT
wrong Therefore in attaching great Importance to thu
experiment The Sarah Sands was built Mt Liverpool
from the plans OF MIR. Granthan consulting engineer
She is about 1900 tons aud $50 borse
power her hrt voyage was commenced on the Goth OF
january under the command OF Capt Thompson and
having encountered most gales and few delavs
she reached New York in 20 days 10 hours To gve
some idea OF The state Of the weather have been In
formed that tho Halifax steamer. which preceded the
Sarah Sands was upwards II 10 days to Boston ana
some OF the finest Of the sailing packets were upwards OF
90 days Thi. esta dishes the question az regards The
sailing qualities Of such vessel The next thing to ba
considered is the amount of stowage In addition 10 tho
space required for the machinery and Goals hese DC
cupy less than the length OF the vessel

We may therefore Justly this a new era In
RI not nj
TAKEN any previous step In this Important branch
OF our national strength There other features con
nectsd with the sarah Sands that deserve notice and
add greatly TO the merit OF the experiment
We have been assured that. contrary 10 all nrecou

vessel about IL knots and that the average spsed

vessel that 1t Is many feet below the water line and acts
as ballast for the ship
About three years ago MIR. Grantham read paper n
copy OF which before us ut the Institution Of
CNl Engineers in which he stated his views and nj the
same time submitted plans TO the Admiralty suoh as he
has since applied to the Sarah Sands IL does not ap
pear That other engineers agreed with him In the
opinion lac had formed and since then large orders have
oeen given out by the government for engines for
reanerr soae " thsse worked by spur wheels or
with the intention Of driving the pstons high veoc
Ties both OF which plans MIR. Orntham has shown to
be unnecessary. The Lords Of the Admiralty now In
Office, however, hearing Of the the Sarah
sands sent engineer to inspect her and his report
has been highly satisfactory Had MIR. Grantham not
had opportunities OF accomplishing his plans In the
course OF his private business the results ne Laa shown
might still have remained unknown or others might
stepped In to reap tho reward Justly due TO him we
trust he will not stop here but pursue this mt
subject when we may hope to still further irnprorc
