Grandfather Mole in "Stubborn As Ever"

Farmer Green hadn't finished ploughing his first furrow before Mr. Blackbird and Grandfather Mole began breakfasting on the angleworms that the plough turned up. Very soon Mr. Blackbird began to regret his bargain with Grandfather Mole, for Grandfather was even a greater eater than Mr. Blackbird had supposed. Mr. Blackbird began to be afraid that there wouldn't be worms enough left for himself. "This is a fine place to dig," he remarked to Grandfather Mole in what seemed a careless way. But he watched Grandfather Mole narrowly, with a grin on his face, to see what the old chap would do.
