Of course the bottom might have cracked all to pieces, but it was quite heavy and Jerry was very careful. It came off wonderfully well, though rather jaggy. Jerry tried to grind the cutty edges off by rubbing them against the rock, but it did n't work. Then we remembered being very thirsty once on a long picnic-walk ages ago, and Father wrapping his handkerchief around the top of the tin can the soup had come in and giving us a drink at a pump. So we knew that we could do that with the broken bottle. Jerry dodged out into the rain through the tide-pools and came back after a while with some water.
