car window into bits and struck the kind
old face, full between the eyes. A quick, startled cry--a pitiful
fumbling of kind old hands before shattered spectacles and eyes suddenly
blinded--and the moving picture seemed to fade away. The twins were left
with the sickening fear that perhaps little Jim's grandmother might
never see him after all.

"Oh! oh!" gasped Betty, rubbing her eyes. "How terrible!" Bob caught
Sure Pop by the arm.

"Did we imagine it, Sure Pop--or was it true?"

"Too true," said Sure Pop, sadly. "It happens almost every day
somewhere--where boys throw stones at the cars 'just for fun'!"

ADVENTURE NUMBER TWELVE

GETTING DOWN TO BUSINESS

"And just to think," said Bob, as the three sat on the home steps
talking over their exciting trip on old No. 777, "just to think of how
many boys and girls are killed on the railroad tracks every day!"

"Every day," echoed the little Safety Scout, "and all over the world. Go
into any village graveyard along any railroad, and you'll find the grave
of some boy or girl who has been killed trespassing on the railroad
tracks. No way to save them, I'm afraid, till folks wake up to the fact
that it's not so much the tramps who are being killed this way--it's the
children!"

"It's just awful," said Betty, puckering up her brow in a thoughtful
scowl. "I think we ought to do something about it."

"What, for instance?" Sure Pop was watching her sharply.

"Well, something to put a stop to it. Surely we could find _some_ way of
teaching the boys and girls how to play safely; and then when they grew
up they'd be in the habit of _thinking_ Safety. Then they'd teach
_their_ boys and girls--and all this awful killing and crippling, or
most of it, would be ended."

"The trouble is," said Bob, "in going at the thing in too much of a
hit-or-miss style. We could do some good by talking to the few boys and
girls we could reach, but not enough. Why can't we organize?"

Sure Pop's eager face lighted up, overjoyed at the turn Bob's thoughts
were taking. "You can," he said quietly.

"Why, sure!" went on Bob, getting more and more excited as the idea took
hold. "Let's get busy and organize an army of Safety Scouts right here.
We've already got the biggest thing in the Safety Scout Law at
work--don't you see?--our 'One Boost for Safety' every day. We can get
some more Safety Scout buttons made, and as fast as a boy earns his--"
