receive a parallel vise, which can be fixed at any angle for angular
cutting. The articulated lever carries a saw of 10 in. or 12 in.
diameter, on the spindle of which a bronze pinion is fixed, gearing
with the worm shown. The latter derives motion from a pair of bevel
wheels, which are in turn actuated from the pulley shown in the
engraving. The lever and the saw connected with it can be raised and
held up by a pawl while the work is being fixed. In small work the
weight of the lever itself is found sufficient to feed the saw, but in
heavier work it is found necessary to attach a weight on the end of
the lever. The machine is fitted with fast and loose pulleys, strap
fork and bar. We are informed that one of these machines is capable of
making 400 cuts through bars of Bessemer steel 4 in. diameter, each
cutting occupying six minutes on an average, without changing the
saw.--_Industries_.

A RAILWAY THROUGH THE ANDES.


The railway system of the Argentine Republic is separated from the
Chilian system by the chain of the Andes. The English contractors,
Messrs. Clark & Co., have undertaken to connect them by a line which
starts from Mendoza, the terminus of the Argentine system, and ends at
Santa Rosa in Chili, with a total length of 144 miles. The distance
from Buenos Ayres to Valparaiso will thus be reduced to 816 miles. The
Argentine lines are of 5.4 foot gauge, and those of Chili of 4.6 foot.
