The strange man turned and hurried off down the street, and after looking toward him for a few seconds the Curlytops and their chum again hastened along, following Top, who grew more excited all the while.

Into the yard of the Martin house dashed Top, closely followed by the children. But the dog did not stop at the house, nor did he run toward the barn where the other pets were kept. When Ted, Janet and Jimmy went over to Jimmy's house they had left the two dogs and the two cats playing outside the barn. Now there was no sight of Snuff and Turnover, nor of Skyrocket, the other dog.

Down past the barn and toward the brook into which Trouble had more than once fallen, ran Top, the trick dog.

"Oh, Trouble must have come back and have fallen in!" cried Janet.

"I don't believe so," said her brother. "If Trouble was in the water you'd hear him howling."

"Unless his head was under," suggested Jimmy.

"Yes, unless his head under," agreed Teddy. "But I don't believe it's Trouble. If it was anything like that, Top wouldn't come all the way to your house after us, Jimmy. He'd have barked and have gotten someone around here to come to the rescue."

"There isn't anybody home at our house but us, and we weren't home," explained Janet. "Mother and Trouble are down town, and Susan, our new girl, has gone out."

"I guess that's why Top came to us," Teddy said. "But where is he going, anyhow, and what is the matter?"

Barking and still wagging his tail, to show how glad he was that the children were coming where he wanted them, Top led the way down along the brook. The Curlytops passed the place where they had played ships the day Trouble was sent afloat in the box—the day Uncle Toby's letter came, telling about the pets he was leaving.
