Robinson got up and with great effort walked to the spring, and there he cooled his burning feet and gathered some large leaves, which he bound on them. he decided to remain in his cave a few days, for he had enough food stored up to last him some length of time, and he planned how he might make himself a pair of shoes. as soon as his feet were well, he sought out some thick bark and put fastenings of tough, strong fiber on it. these served very well to protect his feet, but he needed to have some further protection from the sun. it beamed so hot that his hat was not enough, so he made an umbrella out of leaves like his hat.
