"Oh, Ted, unfasten Sky, or he'll eat Trouble up!" laughed Janet.

"Are you going to sail that big box for your ship, Trouble?" asked Ted, as he loosed the dog.

"Yep! Dis box my s'ip," announced the small boy. "I sail it!"

"Well, don't sail it near ours or you'll upset our ships—yours is so much larger, dear," begged Janet.

"I be ca'eful!" Trouble promised. "I find this big box for my s'ip in kitchen, an' Sky drag it here for me!"

"Yes, Skyrocket is a good dog," said Ted. "Hi there! Don't wag your tail so near my ship, or you'll upset her before I beat Jan in the race!" shouted Teddy, as the dog, in his joy at being with the Curlytops, nearly spoiled their plans for having fun.

"Here! Go chase that!" cried Ted, tossing a stick far down the brook. And as Skyrocket splashed into the water after it, a loud whistle was heard across the field on the other side of the brook.

"There's the postman!" called Janet.

"Yes, he's coming here, and he's got a letter in his hand," announced Teddy. "He's taking the short cut."

Sometimes the mail carrier came across the lots near the Martin home, as he was doing on this occasion. The Curlytops ceased the loading of their ships long enough to run and meet the carrier.
