The upper air lock is an emergency lock for use
by the men in escaping in case of the flooding of
the tunnel. The accumulation of water in the
excavation is forced out of the air chamber by
means of the air pressure through a pipe built
within the bulkhead, the water thus falling to a
sump outside of the wall, from which it is pumped
to the surface, the lift being 60'.
Owing to the water being very dirty and gritty,
the water cylinder of this pump is supplied with
a removable iron bushing. The pump is operated
by compressed air, the exhaust of wliich is delivered
into the compressed air chamber of the
tunnel, where it is again utilized. The Cameron
pumps are especially adapted for this work, being
compact and strongly built, having few working
parts, and no outside valve gear nor rods to become
broken or to get out of alignment. The construction
of their operative mechanism is such as
to give equal efficiency with compressed air or
with steam. The A. S. Cameron Steam Pump
Works, having their general offices and works at
the foot of East Twenty-third street, New York,
manufacture these pumps. Over a score of Cameron
horizontal plunger and piston pumps are in
service at various parts of this tunnel; in fact,
over a hundred are solving the unwatering problems
in numerous parts of New York's subways
and tunne's. W. I. Aims is the engineer in charge
of the work for the New York Tunnel Co., and to
him we are indebted for the foregoing information
and illustration.
A jury at Rutland. Vt.. has awarded to the Patch
Manufacturing Co., of that p'.ac-e, a verdict for
$2,500 damages against the local machinists'
union. In 1903, members of Protection Lodge No.
215, machinists' union of Rutland, went on a
strike against the Lincoln Iron Works of Rutland,
whicn are located within the property of the F. R.
Patch Manufacturing Co. The usual methods of
picketing, urging applicants for work to avoid the
place, were followed, and tne Patch company
brought suit against the union on the ground of
a conspiracy to prevent it from employing help
and to injure its property. If the union fails to
pay, the Patch company will issue execution on
the judgment and in default of collection will
proceed against its members one at a time.

The annual convention of the Western Federation
of Miners was opened at Salt Lake City, Utah,
on May 22. The principal matter to be decided
is the attitude which the federation shall assume
toward the movement for the organization of a
new industrial labor body of national scope and
which will culminate in a convention to be held
in Chicago this month at the call of Eugene V.
Debs. The Western Federation of Miners has
always held aloof from the American Federation
of Labor and it is therefore considered probable
that the Debs movement will receive its support.
