caption 1: At work on a shaft with the oxy-acety-
lene torch. The powerful flame cuts
steel as easily as a knife cuts cheese
caption 2: Arivet-cutting gun for punching out coun-
ter-sunk rivets. A bar is placed against
the rivet-head and the gun does the rest
caption 3: A side lead beveling-machine that works
automatically helped speed up the fit-
ting of a ship's timbers in war days
caption 4: The slow and expen-
sive sledge and cut-
ting-bar method of
getting rid of rivets
and nuts that can-
not be turned has
given place to the air-
operated cutting-gun,
which works quickly
and can go into ac-
tion in a narrow
space. Three men
make up a gun
crew
caption 5: Tom Sawyer would
have had an even
easier time persuad-
ing the other boys to
do his fence-painting.
for him if he had had
“this paint-spraying
machine. It does the
‘work of six men, and
by its aid new ships |
et their christening
suits as if |
caption 6: This overhead cableway makes it

of material easily and quickly.

may be bbtained by comparing the
masts with the man standing at the
foot of the one at the extreme right
