In view of the almost daily disastrous conse.
quenccs attendant steam explosions any invention
calculated to insure the greater safety Of human life
be Of paramount importance to tho public. Some
days ago the subject of the "Corrugation Of Iron was
noticed in the columns Of this paper follows: It
is difficult to realize without practically testing It, the
enormous increase Of resisting power impaired to
sheet or plate Of iron by what s known % corrugaon
Prior to this instantaneous change Of FORM You might
roll it with thumb aud finger like pastebOard; the
change once effected you may stand and even jump on
| Mr.. Richard Montgomery, widely known as an In
yentor has patented applications Of this principle 70
Of boiler plate, railroad cars, &C.. &c. He has also
patented machinery and processes which greatly re.
duce the cost Of cOrrugat0n and of the rapid produc
ton Of boiler plate, beams &C. Unlike most inventors
present outlay Mr. Montgomery proposes to begin with
saving in first cost while doubling the efficiency Of
the product His boiler BEAM car, costs less and is
worth far more than the best hitherto employed"
Yesterday. at the iron store Of Henry L. Person No.
"a Broadway, the corrugated arch for steam
boiler submitted to practical test in the presence
Of several gentlemen among Others, two Of the Govern
ment Inspectors for steam boilers Mr. Hopper and Mr..
Douglas, who testify as follows:

This certify that this day tested Mr. Richard
Corrueaed Boiler Arch" for steamers,
the used this arch being cut sIteenths
of an inch in thickness and being made without the use OF
stays or braces whatever We have subjected 70 hydro
static pressure 10 pounds per inch without any
change of form; while the present boilers now IN use ere
made Of thee-eghts inch iron having to be heavily
braced and stayed to withstand the pressure above
named showing saving Of oneha the thickness oil IRON 10
the corrugated boiler and greater amount oil heating surface
We would consider 1t great saving in economy and weight
for the steamers the oldashioned fiat plates

RICHARD MONTGOMERY, ESQ.,
The following letter is from Messrs C0ryen, the
eminent engine and boiler builders in this city:
DRY DOCK IRON WORKS. NRw-YoRK,1
OYvIcE, No. 435 EAST TESrHsr., 7
NEW YORK July 8, 1865.
r MONTGOMERY esq-Deor Sir have built and tested
with us lbs pressure cold the section Of arch for
the ordinary surface for marine boilers the arch being made
from your patent corrugated boiler ron and will Withstand
800 lbs Der square inch without change Of shape proving lite
| capabiuy to resist pressure without ssys
Apy required be used in practice the saving In
20 per cent and saving OF less thick
ness when the gated iron used When you combine
these two impor facts proves large saving In the con-
,truction of boiler The saving OF weight In boiler made
Of would weigh third less than ofequA
heating surface made Of fiat iron. Yours respectfully
