THE MECHANICS CLUB.

The regular semi monthly session of the Mechanics
Club at the rooms of the American Institute on We'd
nesday evening, drew out as usual, considerable
amount of valuable information.
Steam for ADenne RaiirOads.-Mr. D. MIN
announced that measures were in progress for
testing the applicability of steam power for City Rail-
roads. Each is designed to be run separately, as
at present, with equal facilities for starting and stop
ping for passengers. The engine department IL to be
very compact and light, and is intended to be placed
either the top of the car or under the seat. new
form of exhaust pipe had been invented by the speaker
which he called "hushing throat" and he conveyed
the impression that car so arranged and provided
had been for time in progress, and might be
pected soon out on the track.
Cheapeniag of C0rpets--Mr. THOMAS GROSSLY of
Boston, the patentee and manufacturer of the new
Crennille carpeting, exhibited small brass model OF
printing press for this species of manufacture The
machine was patented in 1854 in own and foreign
countries. but had been allowed to remain. quiet until
large one could be finished and tried. This had now
been accomplished with such success that the first
yard of stuff passed through the machine unexpectedly
came out absolutely perfect. The manufacture OF
rich many coored carpetngs is usually very slow and
extensive. Colors dyed in the wool are fast or
transient according both to the kind of drug aud the
degree Of heat employed in steamng. Scarlet is
fast color as it is heated to 2l2; but buff produced
by the same drug is heated only to blood-warm, or
t6ereabouts and is liable to fade when in use 1t was
very difficult to weave large number OF coors ana
only small quantity of the wool employed came In
sight. To remedy all these evils, Mr.. Whytock of
Edinburgh invented process OF printing tapestry

had engaged very largely in the manufacture. The
method was that Of printing the warp alone by slow
process large cylinder, and afterward weaving IL
as carefully as possible In printing, sne tints were
equally applied to the whole, which rendered printed
colors more enduring than dyed. The steaming in
either case was supposed to open the pores OF the
wool and allow the coloring effect TO penetrate.
Rollers cannot print heavy carpets well, as the
cooring matter cannot be retained but squeezes Tor

must be loaded very heavily with coors and pressed
very powerfully for some time upon the goods. ms

prevent mixing. He considered the machine capable
of producing very fine dress goods and very nch pa

had counted on one piece Of very expensive foregd
goods 1870 distinct coow The great point 10 the goods
20 produced is the perfect register or fitting OF each
impression exactly TO its place without any OF the
overlapping and distortions generally observed This
is partly owing to a peculiar method Of holding aud
moving forward the fabric after each impression, which
psures the absence Of any stretch or irreguariy.
Another point il the prac cabity of printing paper

that the color st printed would be dry before reach
ing the last FORM ready to receive another color upon
the rst when necessary. II is in this way that the

Whitmaish, and employing gaH or alcohol instead OF
solid fuel. Bread was baked and distributed to the
audience in few minutes. The apparatus appears
quite safe, very efficient, and perfectly controaole.

Several other novel and useful affairs hastily
