air, lay there moaning softly.

Bob knew that queer, unnatural angle of the boy's right arm, which lay
awkwardly stretched out beside him, as if it had never quite matched his
left. The arm was broken.

"Here, here!" roared the tailor, gently picking the little fellow up and
carrying him to the elevator. "Will you crazy fellows never learn? Only
last week, somebody hollered 'Fire!' just to see the other fellows jump
up and run, and broke that poor little Levinski's collar bone! And now
look at this!"

"The old fellow's right on that score," was Uncle Jack's remark as the
twins followed him to the street car, each hugging tight a big
pasteboard box with a brand new Safety Scout uniform inside it. "Those
lads meant no particular harm, but that certainly was about as far from
a square deal as one fellow can give another. These 'practical jokers'
who will yell 'Fire!' or run over a boy smaller than themselves--well,
if a Boy Scout had no more sense than that, he'd be drummed out of the
service!"

Once on the way home, when the car stopped at the corner, he pointed up
to a fire escape on a big flat building. "There's your flower-pot risk
over again, Betty. Even worse, for this time they're on the fire escape
steps where folks would fall over head first in case of fire. And see
that girl leaning against that rickety old porch railing on the third
floor! Certainly there's plenty in sight for a Safety Scout to do!"

That afternoon they visited a large machine shop across the river. To
their great delight, Bob and Betty were allowed to wear their new Safety
Scout uniforms, leggings and all. They stood very straight as they
waited for their companion to get a permit at the Company's office.

"Those new uniforms are going to be about as good an 'ad' for Safety
First as anything we could have," remarked Uncle Jack, leading the way
into the big machine shop. He had caught the admiring glances that had
followed them from the older people and the longing looks that the boys
and girls had sent after them all the way over.

"We haven't done our 'Day's Boost for Safety' yet, though," said Betty.
"I don't know but we ought to do our good turn every morning before we
start out on any trip--I just hate not to get my button right side up
till so late in the day!"

"Those girls have pretty neat looking uniforms of their own, haven't
they?" said Bob, a little later, as they gazed down a long row of punch
presses which were pouring out
