Yeste.nclay Crimean invalids, to the number of 104
min of all ranks, belonging to various regiments, were
medically inspected at Fort Pitt Hospital by Dr. J. R.
Taylor, preparatory to their going before a Chelsea
board of ohicers to receive their discharge.
The finding of the court-martial which was held at
Chatham barracks on Tuesday last for the trial of Pri-
vate William Dowell, 32d Regiment, on a charge of
baying wilfully blown off his right hand at Chatham
with the view of being discharged from the service, has
been made known to the troops at Chatham, having re-
ce.;ved the approval of his Royal Highness the Com-
maader-in•Chiof. The prisoner is sentenced to 168 days'
imprisonment,, bat he is not to be discharged from the
service.
The Limerick papers announce the death of Staff.
'Surgeon Augustus Henry Cowan, who had been attached
as chief medical officer to tha Depot Battalion in Lime-
rick since its formation. Dr. Cowan had seen much ser-
vice with the British army in the East Indies and in
China. He was formerly attached to the 48th Regiment
.o.nd also to the 7th Fusileers. He received his commis.
*ion as surgeon of the second-class July 2, 1841. Dr.
Cowan wan on Tuenday last proceeding to the military
hospital in the New Barracks, the approach to which is
t present intersected by a ditch about three feet deep,
ig which waterpipes with plugs are being laid for the
pre tection of the barracks from fire. While attempting
tart oss this cutting he fell in, and received severe in•
jury, with a severe shock to the nervous system. He was
remai, ed to his residence, where was assiduously at-
tendeti by Drs. Hanlon and Gore, but expired at 4
o'clock ,on Friday morning.
The ill...thod invented and introduced by Mr. Wether-
hed, later member of the United States' Congress, for
.steam, having been submitted to various
superheati.vg
processes during the last six months in the dockyard at
Wooly' lob, b, sa at length assumed a practical form.
During the ehaties of experiments to which the system
was subjected it appears that various improvements sug-
gested themsel va a from time to time to the engineer de-
partment there. .In this manner it was considered ad-
visable to prolong the trials, and thereby, if possible,
render the system (so mplete. Prior to the late voyage of
the Dee to the Western coast of England the machinery
was fitted up with the appurtonaaices necessary for the
final test of the system with its stipulated improvements.
The apparatus was at work the whole voyage, which
was specially extended as far as Land's-end point and
back to Woolwich, at the increAsed speed of from 7 to 9
knots an hour, the result of whic,'i exceeded anticipation.
It is understood that the average economy realised in
fuel amounts to about 35 per cent.. The apparatus con-
sists of a number of iron pipes being carried along the
front of the tube plate, and extending into the chimney,
into which the ordinary steam passes, and which gradu-
ally becomes superheated to about 500 deg. It is then
alloyed, or mixed with the ordinary steam, in about
equal proportions, bringing the temperature cf the
mixed steam to about 340 deg., in which state it is ap-
plied to the purposes of the machinery. The system of
simply superheating without mixing the steam bas been
known for some time past in France, and has been at-
tempted on many occasions, but without success, which
is attributed in a great degree to the imperfection of the
French machinery, which is less complete than our ewn.
In the first course of orperimente a difficulty existed—
namely, the burning and consumption of the wadding.
After many fruitless attempts, this difficulty was at
length got over, thus rendering the method perfect.
The following appointments were made yesterday at
the Admiralty :—Commander W. Mould, to the Majes-
tic; H. L. Gully, naval cadet, to the Highflyer ; B. N.
Murphy, assistant-surgeon, cocfirmecl, to the James
Watt ; W. P. Scott, assistant paymaster in charge, to
the Scorpion ; W. H. Gribbeil, clerk, to the Highflyer ;
H. E. Roy, acting clerk, to the Colossus.

A LETTER FROM TILE MORMON
COUNTRY.

A. letter has been received this week (lays the Kcndal
Mercury) from John Strong, whom many of our readers
well know, and who for a long number of years carried
on the business of a blacksmith in Allhallows-'ane, Ken-
dal. The letter is dated " Grovow City, Utah Territory,
May 25, 1856," and the writer says :
" On leaving New York we sailed, by steam-packet,
for about 100 miles; then we took the railway to Phila-
delphia, and thence to Pittsburg by rail, a distance of
nearly 600 miles. We then took a river which led ui into
the great Mississippi, which took us up to St. Louis,
where we stayed fur about a week. We then took the
same boat and landed at a small place called Hutchin-
son, close by the river ; we stopped there two days, and
then we started with oxen and wag4ons to Mormon
Grove, a, distance of five miles, where we pitched our
tents and lived in kbem until we bad made everything
ready for a fair start across the plains, which [exceeded
1,290 miles. We remained there six weeks, and left
the Grove on August 4tb, and landed in Salt Lake Val-
ley on the 25th of October. I must inform you that we
had a pleasant journey consideri►,g the road we bad to
travel.

" I have bought two lots of land in this city, and
my son John has bought two lots joining mine, and
we are going to build this summer, if all be well. We
have got our crops in.
"The land here is good, and of a sandy nature ; the
rain is not so frequent here as in England ; but when
the land gets dry, we are obliged to water it from the
streams that flow from the snowy mountains. We have
plenty of water streams here, abounding with fish ; we
can get trout from 10 to 12 lb. we'ght. This is a beau-
tiful valley, surrounded with snowy mountains and a
large lake on the west side, which renders it very
healthy, and the air is so clear that you can see the dis-
tance of 30 miles ; you can see the cattle grazing on
the range for six or seven miles. There are a few tribes
of Red Indians in these mountains, snd they sometimes
come to visit us. They are very peaceable, and our
people treat them kindly.
"We are all well; John is living with us; Mary is
here and is married to Thomas, the third son of Roger
Ferrer; Agnes and William are with us ; Hannah is
living in the city. in a good place ; Joseph is shepherd.
ing every day ; Eleanor, Elizabeth, Ann, and Miles are
all doing well, and we have all enjoyed good health
since we left England.
" Dear Brother John,—l have often thought about
you, as well as many others, and the advice I gave to
you when we parted. T now wish to inform you that
my faith is as strong in Mormonism as ever it was. I
still know it to be the work of the Lord, and besides
it there is none else. I would wish you, and all who
desire to be saved, to look out for yourselves. This is
my testimony to you, and the desire I have for you,
that you may embrace the same, and that we may
have the privilege of being brothers and sisters, through
time and through eternity. This is my desire for you.
"My wife likes the country well. Gist) our love to
Mrs. Smith, Mrs. Abbatt, of the Black Swan, to the
people at Endmoor, &c. . . . I must now conclude
by praying the Lord to b!ess you all.

"JOHN STRONG."

SLAVEHOLDING INTOLERANCE.

The Hochwathter, a German Republican paper, pub.
balled at Cincinnati, has transferred its Presidential
ticket from the first to the third page. The reason for
this change the editor, in a recent number, explains as
follows :
" We have been obliged to take the ticket of Fremont
and Dayton from our first page, in consequence of the
annoyance and persecutions which it brought on our
subscribers in the southern states. Seine of them have
been threatened with mob visitation, tar and feathers,
lee., unless they would discontinue taking that abolition
sheet.' Such is freedom of the press, as understood by
the nigger-democracy ! Such is the respect entertained
by the south for the right of conscience. The inhabitant
of a slave state who does not own negroes is himself
tyrannised over like a slave, and dare not even read a
newspaper that has not passed the censorship of his
masters, the traffickers in human flesh and blood. Is
this to serve as an example of what awaitsui‘swhenever
slavery shall be extended over the free West? ir. r.Bucha-
nan is a worthy candidate of the party that refuses to
recognise the freedom of the press. He, too, bas
never
respected this fundamental principle of liberty. When,
some years since, a motion was made in the Senate to pro-
hibit the mails from circulating incendiary newspapers
and other publications in the South, Mr.Ruchanan's vote
was recorded in favour of this attempt to muzzle the press.
This was more than the great fire-eater Calhoun himself
could swallow, and be voted in this case against his c)nfa-
derates. But Mr. Buchanan was at all times ready to out-
strip southern politicians in servility and submission to
the behest of the slo.ve-drivers, and thus voted for a mea-
sure from which even Calhoun recoiled. Whoever, there-
fore, is opposed to freedom of the press, will veto for
Jas. Buchanan."
