"It seems that my laws have not been obeyed, for even these monstrous spiders defy me by means of Magic." "Never mind that now," said Dorothy; "let's see what we can do to get out of this trap." They now examined the web with great care and were amazed at its strength.

Although finer than the finest silken hairs, it resisted all their efforts to work through, even though both girls threw all their weight against it.
"We must find some instrument which will cut the threads of the web," said Ozma, finally.

"Let us look about for such a tool." So they wandered among the bushes and finally came to a shallow pool of water, formed by a small bubbling spring.

Dorothy stooped to get a drink and discovered in the water a green crab, about as big as her hand.

The crab had two big, sharp claws, and as soon as Dorothy saw them she had an idea that those claws could save them.
"Come out of the water," she called to the crab; "I want to talk to you." Rather lazily the crab rose to the surface and caught hold of a bit of rock.
