"And I'll take my stout cane and my own strong legs and trot toward the Lake, if you don't mind," decided Grand-daddy. "You and Buster can finish your pleasure trip a little at a time, but I have business to look after and a house to hire before the rest of the family catch up with us."

He started off at a brisk pace. Buster sat on the front seat and nibbled ginger cookies, while Limpy-toes limped back to find the lost key.

By-and-by, Buster's cookies were all eaten, so he strolled off to help Limpy-toes.

"Never mind, Limpy," he said, looking up into his big brother's sad face. "It is a fine automobile, if you do have to twist it often. We can have nice rides around the Lake."

But Limpy-toes would not be comforted.

"I wanted an automobile that would fetch Dr. Grand-daddy to his patients very quickly. I must study until I make better power than this clock spring. Ah, here is the key! We must hurry, or Uncle Squeaky will catch up and laugh to find us by the roadside."

Grand-daddy and Pa Field-Mouse were standing on the bungalow steps talking earnestly together when Limpy-toes drove up.

"A fine automobile, Pa Field-Mouse," said Grand-daddy, waving his paw. "My grandson is a great inventor; he will be famous some day."

"Ah!" cried Buster, "how good our Gray Rock Bungalow looks! See the pretty hemlocks and sweet ferns, Limpy."

"Wait until you see the fine house the neighbors have built for me!" exclaimed Grand-daddy. "They felt sure that I would come. Silvy would call it Wild Rose Cottage. It is a real bower of roses. Here come our folk, now. Wait and I'll tell you all about it."
