"I will have to make me a little yard in front of my cave," he said, "for my goat to live in." But from whence must come the tools? He had neither hatchet nor saw. Where then were the stakes to come from? He went in search of something. After hunting for a long time he came upon a kind of thistle about two feet higher than himself, having at its top a red torch-like blossom. There were a great many of them. "Good!" thought Robinson. "If I could only dig up enough of them and plant them thick around the door of my cave, I would have just the thing. No one could get at me, nor at the goat, either. The thorns would keep anything from creeping through, peeping in or getting over." So he took his mussel-shell spade and went to work. It was pretty hard, but at length he succeeded in laying bare the roots of quite a number. But he could not drag them to his cave on account of the thorns sticking in him. He thought a long time. Finally, he sought out two strong poles or branches which were turned up a little at one end and like a sled runner. To these he tied twelve cross-pieces with bark. To the foremost he tied a strong rope made from cocoa fiber. He then had something that looked much like a sled on which to draw his thistle-like brush to his cave. But for one day he had done enough. The transplanting of the thistles was hard work. His spade broke and he had to make a new one. In the afternoon he broke his spade again. And as he made his third one, he made up his mind that it was no use trying to dig with such a weak tool in the hard ground. It would only break again. "If I only had a pick." But he had none. He found a thick, hard, sharp stone. With it he picked up the hard earth, but had to bend almost double in using it. "At home," he thought, "they have handles to picks." The handle was put through a hole in the iron. He turned the matter over and over in his mind, how he might put a hole through the stone. But he found no means. He searched out a branch with a crotch at one end. He tied the stone to this with strong cocoa fiber and bark. How his eye glistened as he looked at the new tool! Now he began to work. He first loosened up the earth with his pick, then he dug it out with his spade and planted in a high thistle. Many days he had to work, but finally one evening the hedge was ready. He had a row in a semi-circle in front of his cave. He counted the marks on his calendar tree. The day on which he had begun to make his hedge he had especially marked out. He had worked fourteen days. [Illustration: ROBINSON'S TOOLS] He had completed his hedge with the exception of a small hole that must serve for a door. But the door must not be seen from without. As Robinson thought, it came to him that there was still place for two thistles on the outside. He could easily get in, but the entrance was difficult to find from the outside.
