steam Of Its power to do mischief while its ca
pacity for good Is wholly preserved, the oon-
trivance that will do it must be regarded as
not only wonder but blessing. Mr.. Reeder
thinks he has accomplished this purpose, and
that opinion is backed by the Intelligent and
scientific"
The following letter from Capt Harrison, .
local steamboat inspector at Nashville, has
already been published; but it is thought best
to give it place here. for the reason that, as
he has received the endorsement of the Board
Of General Inspectors as gentleman of pro-
fsssional skill and judgment, more than ordi-
nary reliance will be placed on his statements:
NASHVILLE: June %, 1856.
Nh. j. NJ. REBDER-Dear Str: You equest
my opinion and experience of your Safety
Guard. It affords me pleasure to testify to
the intrinsic worth Of any appliance attached
to steam that has tendency to decrease the
risks Of human life so frequently caused by
steam and its mismanagement, whether by
want of skill or from the most skillful whom
caught of their guard.
Being, on several occasions, q passenger on
the steamer VIM. Garvin, to which was at.
tached to the boiler Of the boat one of your
Safety Guards, was much satisfied to witness
its certain detecti on Of excessive pressure be-
yond the weight attached for its prevention,
and in every instance found, when such ex.
cess presented itself, your guard instantly,
with unerring certainty, ION comparison with
we'll regulated steam gauge,) never failed,
In SINGLE instance, of raising, at the exact
degree designated, and dampening the fuel of
the entire fre-surface instantly, SO as to re
duce steam below the standard designated
fully satisfying me that it was reliable as self.
acting, and that if every human agency had
been withdrawn from the boat an explosion in
no svsnt could have occurred. In addition
thereto, on one trip, before day, whilst in the
act of towing wood fat, by mismanag cement
the fat was caught under the guard of the
boat and in her wheel, which prevented the
engine from operating, causing a slight de-
rangement of the machinery, that, by the at
tachment of counter weight to the valve
line Of the Guard, steam was held during the
entire time to pressure Of fifty pounds, and
thus insured safety to all On board whilst the
entire crew was occupied in extricating the
boat.
Yours, truly, Ii. II. HARRISON
The following letters have been recently re-
ceived, and are submitted with the single re.
mark that they are from gentlemen of e1pe-
rience in the matters of which they speak:
MEMPHIS, July Is, 1856.
SIR After close and scientific examina-
ton of your Safety Guard. L am fully con
WINGED that it is one of tho greatest inventions
of the nineteenth century, destined to save a
goodly number of human beings from an un-
timely grave.
Twenty years practical experience with
steam boilers and different apparatuses for
preventing them from bursting, in this and
foreign countries enable me to say that be-
lieve none so effectual in case of danger as
your Safety Guard. This Safety Guard should
be part Of all machinery operated by steam.
You may expect to meet with great deal
of opposition because your invention is new,
but no engineer, competent to investigate 1t
sc,enti fcaliy, will object to it or its mode of
operation. Respectfully yours,
A. Ross, Engineer.
