Whitefoot the Woodmouse by Thornton Burgess, Fiction, Animals, Fantasy & Magic, (Hardcover)

Whitefoot the Woodmouse had been running and jumping all around the inside of the little sugar-house. He loves to run and jump, and he had been having just the best time ever. Finally Whitefoot ran along the old bench and jumped from the end of it for a box standing on end, which Farmer Brown's boy sometimes used to sit on. It wasn't a very long jump, but somehow Whitefoot misjudged it. He was heedless, and he didn't jump quite far enough. Right beside that box was a tin pail half filled with sap. Instead of landing on the box, Whitefoot landed with a splash in that pail of sap!

Whitefoot had been in many tight places. Yes, indeed, Whitefoot had been in many tight places. He had had narrow escapes of all kinds. But never had he felt so utterly hopeless as now. The moment he landed in that sap, Whitefoot began to swim frantically. The more he tried to climb out, the more frightened he became!
