“It _is a work that was a great desideratum, and
must prove of great benefit to the engineering pro_fes-
sion generally, and especially to the tyre in practical
engineering and nieclianical knowled e; in truth it

strikes us, that it would require years 0 labor and P3‘
tient toil on the part of a young engineer to prepare the

’ drawings, and collect the information that will be em-

bodied in this work, and can now be secured for the
trifling sum of $9”—[Scientific Amer.iMa_rch 16, 1850.
In connection with this subject (Iron Railroad S truc-
tures) we take occasion to callattention again to _lVIr.

gineer, who came from Ireland. to Ll‘ is country to ex-
ercise his profession; but fiildlno’ .{.ailroad construc-
tion here, in many respects, di crent from that he
had been accustomed to in Europe, he applied hi_rnsell
to the study of our system ; and tlie_fruits of his re-
searches and investigations embodied in this work, are
well calculated to meet the exigencies oi engineers,

for the Northern Division and pa rt of the Southern
Division of their road, embracing a distance of a-
bout lO5 miles. The rails are to be ot"the H pat-

lineal yard. I They are to be delivered on the Coo-
sa river, at a landing to be hereafter designated,
between Kimulgee ferry and Fort Williams, com-
mencing their delivery on the 1st of November.
1851, and contiiiuiiig it at tlierate offrom 80 to 100
tons er week, until the whole quantity required
(10,500 tons) shall have been cleliverecl. They are
to be inspected by Lewis Troost, Chief Engineer.

It is proper to state to iron masters and capitalists
at a distance, that the country traversed by the Nor-

abounds in excellent iron ore and bituiiiinous coal.
and possesses ever advantage for the successful

GRAHAM’S COMPOSITION,
to Remove and Prevent
Incrustation (or Scale) in
STEAM BOILERS.

HIS valuable compos‘tion having been fully and
extensively tested, is now oflere_d to the public,
as :1 sure remedy and preventive tor incrustations in
steam boilers of all descriptions. _Byits use, all scale
is entirely removed from the boilers of Ocean and
River Steamcrs,Locomotive and Stationary Engines,
in from 3 to 20 running days, according to the size of
the boiler and thickness of the scale. In New Boil-
ers, all incrustation is prevented at a trifling expense.
The preservation of the boiler, great economy of
fuel and labor, safety, and increased speed, are among
the advantages to be derived from the use of this com-
position. _
Orders should state the quality of water used, viz :
“Salt,” “ Fresh,” or “ Brackish.”

TESTIMONIALS.
New York. Augusl 17, 1850.

We have used Graham’s Composition in .he boilers
of the Steamship Southerner, during several voyages
between this place and Charleston. The boilers were
old and very foul with scale, a very large quantity of
which was removed by the use of the composition,
and no new scale was formed.

From our own experience and observation in the
use of the article, we are fully satisfied that it will cf-
fcctually remove the incrustation made by sea water,
and also that it will effectually prevent its formation.

We are also satisfied that the use ofit will be attend-
ed with a great saving of fuel, and that it has no inju-
rious effect upon. iron.

Steamship Philadelphia, 2
New York, August 27, 1850. 5

I have used “Graham’s Composition for Steam
Boilers,” in the boilers of Steamship Philadelphia, on
the voyage to and from Cliagres, and am entirely sat-
isfied that it will remove, dissolve and prevent all
scale or incrustation in salt water boilers.

For the preservation of the boiler and economy of
fuel and labor, I hereby recommend the employment
of this composition in the Boilers of Ocean Steamers.

We have examined the specimen of Gral'iam’s Com-
position for preventing inci'ustation of steam boilers,
and we believe it may be used with perfect safety in
reasonable quantities for the purpose intended,astliere
does not appetr to be any agent in the composition
calculated to injure the iron.

STILLM AN, ALLEN &. C0.‘

Piermont, May 20, ll-‘-.50.

I have used “ Graham’s Composition,” and find it
to produce the intended effect; and lliereby, without
hesitation, .ecominend it for Stationary, Marine and
Locomotive Engine Boilers.

In answer to many II‘lq_lllI'l«’S as to the practical cf-
fcct of “ Gr'ihaiii‘s Composition,” 1 will state that I
have used it in the boiler of the Steam boat Sunwick,
which had become considerably incrustcd with hard
scale from both salt and fresh water. We used 10 lbs.
per day, for three days, without blowing oil‘ the water,
until the fifth day, when all was drawn oil‘. To our
astonishment, we found the wholcintcrior of the boil-
er as clear of scale and smooth as when it came from
the hands of the maker. The following week, We
tried the same quantity in a small steam tow boat.——
.The boiler had old scale oflong accumulation and very
thick. We ran the boat three days without blowing
oil‘, and on the fourth day washed out the boiler and
found it, like the “Sunwick’s,” perfectly clean and
smooth as when new. I am therefore enabled to state
that the use of the composition in these two instances
under my own immediate observation and direction,
has been attended with complete success.
