'You can use my spade.

It's much the best--' So he came along and dug, and when once he was over the wall we kept him at it, and we worked as well, of course, and the hole got deep.

Pincher worked too--he is our dog and he is very good at digging.

He digs for rats in the dustbin sometimes, and gets very dirty.

But we love our dog, even when his face wants washing.
'I expect we shall have to make a tunnel,' Oswald said, 'to reach the rich treasure.' So he jumped into the hole and began to dig at one side.
After that we took it in turns to dig at the tunnel, and Pincher was most useful in scraping the earth out of the tunnel--he does it with his back feet when you say 'Rats!' and he digs with his front ones, and burrows with his nose as well.
At last the tunnel was nearly a yard long, and big enough to creep along to find the treasure, if only it had been a bit longer.
