"We'll be up bright and early, ready for anything," Bob told him. "Whew! but this has been a whirlwind of a day! Glad you're going to take Mother out—that's the only way she'd get a cool breeze tonight, all right!"
"But it can't be as nice as the roof garden, even then!" cried his happy twin, as she lifted out her big box of candy and skipped up the front steps two at a time.
ADVENTURE NUMBER SIXTEEN
WHERE SAFETY WAS A STRANGER
True to their word, Bob and Betty were up bright and early, ready for Uncle Jack's exploring trip.
"We're going to visit one of the big wood-working mills," he explained as they left the house after breakfast. "I'm curious to see the result of Colonel Sure Pop's Safety patrolling, and it seems to me that will be about as interesting a shop as we can begin on. It will be fun to see what they're doing to make it safer for the men—perhaps we can get some ideas for your outside patrols, Bob."
The twins looked around them sharply as they went into the mill by way of its lumber yard. "I don't see anything here that looks dangerous," was Bob's first remark. "Hold on, though—what about those piles of lumber? Don't you think they're piled too high to be safe?"
