fully turned so that he faced
the elevator door.

"That was a risky thing you did just then," he whispered to Betty.
"Three quarters of all the elevator accidents are due to stepping in or
out in the wrong way. Never do the thing halfway, you know. Always wait
till the elevator man stops the car at the floor level and throws the
door wide open."

Next to them in the elevator stood two boys--cash boys in the store--who
were fooling and scuffling so close to the door that the elevator man
cautioned them twice as the car dropped swiftly downward. Finally one of
them brought his heel down on the other's foot so hard that the other
jumped backward, forgetting everything else for the pain. Forward went
his head--bang went his face against the iron grating of the door they
were just passing.

The elevator stopped with a jerk. They carried the boy out and sent for
the store doctor. Bob and Betty never had to be reminded, in all the
years to come, to look sharp when riding in elevators. The memory of
that bruised and battered face was warning enough.

"It's a dangerous machine," said Uncle Jack as they left the store. "A
fellow who will scuffle in an elevator is foolish enough for almost
anything. Here's our next stop," and he showed them into a shop with a
big sign over the double door:

UNIFORMS--READY MADE OR TO ORDER

"Uncle Jack must be going to have a new uniform," whispered Betty to her
twin as the tailor came up with his tape over his shoulders. But it was
not around their uncle that the tape measure went, it was around Bob!

"Yes, the regulation khaki," Uncle Jack was saying. "Cut and finish it
just like this one," and he handed the tailor a photograph of Sure Pop.

"Your turn next, Betty," said Uncle Jack, and to Betty's great delight
and the tailor's surprise, _she_ was measured for a special Safety Scout
uniform too!

Uncle Jack did not stop there. He bought the twins Safety Scout hats of
fine, light felt, made for hard service, and he was on the point of
buying them leather puttees or leggings, but Bob stopped him.

"Canvas leggings are plenty good enough," he said. "The fellows couldn't
afford leather, most of them, and we want them all to match."

"Canvas it is, then," nodded his uncle, and went on making up the
outfits. Betty sighed happily as they followed him into another store.
It all seemed too good to be true! The first thing she knew, they were
sitting at a glass-topped table.
