A
exauined.-I am practical engineer, and have been
for 81 yers connected with the business OF su
periDtsndng and running steamboats,; have examned
the boiler question: my opaion to the Of its
explosion Is, that the boiler showed want from having
the bracipg inches from centre to centre and
about No iron strapped brace bolts; consider
IL to have been q dangerous boiler, and ] have
known the ssme kind Of boiler to be huilt by Dr.
the tubes Of that boiler were placed upon the same
principle o tubes, but being five or six inches dia
meter; this kind Of boiler was put on board the

Of cylinder boilers placed In their stead afterwards
these were taken out and the principle adopted
with rmser tubes those from time to time, gave out,
ton: she at length blew up, and. as understood,
ruined the concern; the thing was then abandoned;
have been always suspicious Of that kind of boiler and
have thought 1t safe from the fact that have
the front tubes when they have been heated; |
vas asked my opinion as regards Mr.. Montgomery s
boiler at New Oreans said IL was unsafe one, I'M
less some radical improvement made in 1t; from
examination believe there plenty Of water in this
Hrgne street boiler and believe that the settling OF the
plate in the front Of the tube sheet red hot from
the intensity Of heat upon the front tNbes and that
when the engine was started that the great irritation
In the water convused through those tubes. aud
caused the explosiop am satisfied, from experience,
that this CONFUSION takes place in all kinds of
boilers, when engines are started, and that when
so small portion Of water is to be acted
upon with great an Intensity Of heat that
1t must inevitably have driven the water from the
front tubes also consider all boilers unsafe where
the screw brace bolt Is applied or what Is called top
bolts; did not mean to give testimony, but MIR.
Nor tgomery made threats to deter me from doing
in thir place, and that my time was occupied I
scarcely had eisure to give evidence have built and
superpteneed great number OF steam vessels, and
never lad any accidents happen to my boilers; the
only safety Is in the gauge cock; it my opinion the
size Of the safety valve had nothing to do With the
Il the exposion valve could have
the explosion under the circumstances; it my opin
ion that no boiler ever made, which could stand
the explosive force which was the cause Of the recent
catastrophe: do not consider the bottom arch Of a
boiler the weakest part; have water vary IN the
boiler eighteen inches In moment OF time; have
known many boilers BURT when supplied with plenty
Of water.
Lswr.nce Reed. residing at AZ Tenth avenue, ex.
amin, en- practical chemist for twenty years;
think the explosion caused by want OF sufficient
quantity Of water in the boiler owing perhaps to the
feed pipes being Of order through the FROST the
