accomplished, and the Board feel sa:ished
that they have obtained. by the perseverance
Of those In their employment. an engine BET
ter adapted TO the purposes Of this road, than
any other yet Invented. The engine in quss-
ton Il % uaeeable as tho best t.ngiish en-
gines, possesses much more power with the
same weight, works with equal. or very near
y equal, facility, on curved and straight

given time, aud Is liable 10 FAR less injury
from wear and tear. than any other known
engine. The objection against the English
engine Of tho present construction, 10, that
tho tubes OF its horizontal boiler are frequent
ly bursting, by which, not only is the expense
Of repairs incurred, but the bursting Of
tube at once extinguishes the FIRE, leaving
sometimes the engine and its train in the mid
do Of their journey. IT, the vertical boiler
used by this company, and the right 10 use
which they have purchased from the inge-
Nous inventor Peter Cooper, ESQ all this is
entirely avoided. In the horizontal boiler,
the fire Is st one end, where OF course the
greatest quantity OF steam Is produced, and
the density Of tho water Is the least; so that
the tubes, where most exposed TO the action
OF the heat, are least protected from it !; and
the fact 10, that the tubes commonly all burst
within q few weeks. Various attempts have
been made To remedy this by producing n
circulation in the water Of the boiler, but
hitherto 10 Is believed without success. In
the vertical boiler, the contrary, the wa
ter on the outside being colder than that which
Is near 10 the tubes, descends towards the
fire and passes up again in bubbles OF steam
to the steam chamber, TO exert its expansive
power in pressing the water Of the boiler
dOwnwards to the very place where the in
tense heat Of the anthracite coal renders eve
ry protection necessary which can be afford
ed to the bottom OF the boiler, and TO the
tubes. In the upright boiler, therefore, with
out tho Intervention Of complicated machine
~ 10 obtain a circulation, Il is produced in
the most efficient manner, by simple and ma
turai causes. Some idea may be formed Of
the value of the vertical boiler, adopt
ed by the Board, from the fact, that after
twelve months use with anthracite coal for
fuel, not one OF the tubes Of the Atlantic en-
CINE has given way, and 10 all appearance
The Traveller Engine, which was first
put upon the road on tho 10th Of October,
and which, like the Atlantic, has n vertical
boiler, fully answers oil the anticipations ia NJ
we're entertained Of its performance, men,
toned IN the report Of the Chief Engineer
The attaching of the pinion, through which
the power is communicated tn the wheels, to
separate shaft, has fully answered the pur-
pose OF giving steadiness TO the machinery,
i and a Il j.
( its wear and tear. The Traveller is an
excellent illustration Of The propriety Of de-
voting every attention TO the vertical boiler
engine, aud exhibits numerous points Of SUI
perior excellence over its predecessor, the
Atlantic. When il il considered that the no.
rizontal boiler engine of England, has been
brought TO its present excellence, after the
| experience and experiments afforded by lis
constant use for q long time, and that il is,
as may be safely said, inferior In point of du-
rability, and power TO generate steam, to the
first attempts with vertical boilers, il is no,
unreasonable to believe, that the latter will
supcrsedc all Others, and every effort will
forthwith be made, TO put a competent mum
Der upon the road.
Besides the Improvements in the locomo
tive engine, others have been made In Tho
machinery used by the company, and particu.
! larry in the construction OF the wheels Of the
csrs-by which an iron rod il introduced in
To the rim Of the wheel when cast, which mo-
only adds to the hardness Of the outer sur
face, by perfeeting the chill, but increases il
q great degree the safety Of the wheel Itself
Improvements have also been made in the
ourtben cars, tending materially TO diminish
the wear and tear Of them aud with a view
TO the employ ment OF steam, The passenger
cars will hereafter be so constructed a. Il
carry neither passengers nor baggage upoT

hrst cost OF them will be effected, and III,
chief cause Of injury TO them will be avoided
AZ the same time, every attention will b,
paid in the construction OF tho carr. 10 rem
