however, doomed to disar pointmsnt. for . message
was received that the owner Of 'he omnibus Vas DC.

by the inmense masres O. dirt that lay upon the
streets. Under these circumstances, no would adj

On Saturday night the visitors Ut the Institute
were honored by display Of fireworks at the
Garden.
We will now resume our detailed descriptions Of
the various articles -

I'D PRINCiPIFs This is Il practical e1empii6on.

system OF type founding for II ID an illustration Of
tho latest advances made in that trade. The ma.
chine combines within itself q whole ma ufaot0ry,
containing . furnace and AL the necessary sppi-
ances, and occupies working space of soout a foot

hitherto ~ attending type making, in tho shape
are many material advantages gained The old
machines could only make tnird the nu ubers Of
types which can be turned by this machine, for
hourly experiments demonstrate that it oaa manu-
facturs 40 ty pes minute. and 200 spaces in the
same time. notwithstanding this, however, tho
inventor, who ia large type founder, has not yet
been able to make proportionate reduction in tho
price Of type, in consequence Of tho operatives
insisting upon being paid by the number OF types
turned out. With all due Difference to the working
mans rights. decidedly Of opinion that the
public should gain the advantages resulting ftom
time-savpg machinery; for il that result DO not
secured thoro il use whatever in any bringing
improved machinery into practice; for II no advan-
tago DO occurred to the pubic, the old machines
need never be superseded The operatives should
be contcpted with fair days wages, and not seize
on that which should 60 to the public. TIE pressnt

founders TO sell cheaper and that result ought and
must be secured.
SUBMARINE DRAwBRIDGB This 10 truly
valuable invention. inasmuch as IL entirely does
away with all the obeoions heretofore urged sgainst
the spanning Of rivers by bridges, aud Albany
neighbour, in particular, wilt rejoice at invention
which will secure them SO nsoy advant 3gss, and
bridges in that quarter Inc bridge in question is
proof against food and fire and offers no obstruo
ton TO vessels passing, for It lowers by ono moro
sgmeats, - may be desired, TO great depth in the
water, and the vessels pass over. after which it
be again raised in few seconds The draw acts
upon movable posts placed upon the bottom OF tho
river, and Dan DO made of any strength desired.
SRIF-DREOTING RAILROAD CAR The principles

tho curves of railroads may be passed bv con-
structed on this plan, without any Of the many in
eonveniences that are now experienced IL is well
known by all familiar wit railroads that
the greatest objection which they subject
ed. Car axes of great strength are twisted off in
great numbers, by the difference in the length Of
the rails in curves and the tangcs of the wheels
the outside rail in contact with the rail, greatly
increasing the friction and retarding the power
of the engine. This invention is designed to
cure both Of these objections; 6rst, oy Civ
ing tho wheels indept ndent motion, by
means OF separate axles; and second, By causing
! thc axles to conform to the radii of the circle
