"What do they wear them for--just to look pretty?"

"You wouldn't have thought so," laughed the forewoman, "if you could
have seen how they fought the first caps and aprons we tried to get them
to wear. They _were_ homely things, even if they were life savers. So we
kept at it till we got something so trim and pretty that the girls would
rather wear it than not."

"Life savers?" repeated Betty. "How could caps and aprons save lives?
Oh--by not catching in the machinery?"

"Just so. It's easy for a girl's hair to be blown into the machines, or
for a braid to swing against a whirling shaft, you see. Oh yes, we had
several girls killed that way, before we tried this uniform. They used
to wear dresses with baggy sleeves,--ragged ones, sometimes. Rings and
bracelets are bad, too; and even these aprons, you'll notice, are
buttoned back so they can't fly out against the wheels. Yes, the girls
all like the idea now. The caps keep their hair from getting dusty or
mussed up. Besides, we find it saves a good many girls' feelings, too,
having them all dressed so much alike."

The same good sense was shown in the other departments, in the working
clothes worn by the men and boys.

"You won't find a man in this room with a necktie on," the foreman told
them. "These are the biggest punch presses in our whole shop. A while
ago one of the men got his necktie caught between the cogwheels and he
was drawn into the machine head first. That was the end of that sort of
thing in _this_ shop!

"Now, as you'll see, long sleeves and ragged or baggy overalls are
things of the past. If a man does wear a long sleeve, he keeps it rolled
up where it can't catch and cost him a hand or an arm.

"Watch the men and boys, and you'll see how careful they are not to look
around while their machines are running. Before they start their
machines, you'll find them looking all around to see there's nobody near
who might get caught in the wheels or belt. These workmen are just as
anxious to give the other fellow a square deal as anybody could be, once
they catch the Safety First idea. It took some of them a long while to
learn never to fool with the other fellow's machine--that's always
dangerous, you know, just like a machine that's out of order. Our
pressmen wouldn't think of starting up a machine which was out of order,
or which they didn't understand--they'd report it to me at once."

"What has been the result
