ROBINSON'S DIARY
Robinson was much disturbed because he had no means of keeping a record of things as they happened from day to day. He had his calendar, it is true. He would not lose track of the time. But he wished for some way to write down his thoughts and what happened. So he kept up keen search for anything that would serve him for this purpose.
Every time he journeyed about the island he kept careful watch for something that he might write upon. He thought of the leaves of the palm tree, the white under surface of the shelf fungus. But these he found would not do. He tried many kinds of bark and leaves. There was a kind of tall reed or grass growing in the marshes whose rind seemed good when dried. He examined the inner bark of many trees. He at last found that the inner bark of a tree which resembled our elm tree worked best. He would cut through the bark with his stone knife around the tree. At about one foot from this he would cut another ring. He then would cut through the bark lengthwise from one circular cut to the other. He could then peel off the section easily. While it was yet full of sap he would separate the soft, tough, thin inner layer of the bark. This usually came off in sheets without a break. When these sheets of bark were stretched and dried they could be used very nicely instead of paper.
Robinson next searched for something that would serve him as ink, and this was much easier to find than paper. He had noticed many kinds of galls of many different colors growing on trees. He did not know what they were, or how they grew, but he had learned in his father's store that ink was often made from galls gathered from trees. "Anyway," he thought, "I can get ink from the cuttle-fish." He had watched this animal get away from its enemies by sending out a cloud of purplish fluid, in which to hide as it darted away. He had learned also that indigo is made from the leaves of a plant. He had noticed a plant growing in the open places in the forest whose leaves turned black when dried.
Robinson gathered a quantity of gall-nuts and soaked them in water. To the black fluid thus obtained he added a little rice water to make it flow well, and this served very well as an ink. He kept his ink in a cup made from a cocoanut shell.
He was not long in getting a pen, though the lack of a good sharp knife made it hard to make a good one. In going about he had gathered a quantity of large feathers. He saved these for the time when he should have his paper and ink ready. Now, he cut away a quill to a point and split it up a little way. He was now supplied with writing materials. "Is it not wonderful," he thought, "how all our wants are filled? We have only to want a thing badly enough and it comes."
Robinson began at once to write down the date for each day and the main thing he did or that happened on it. He called this his diary. He had now a better way of keeping time than on his tree calendar. He did not need it any more.
You have no doubt wondered how Robinson could work in his cave, especially at night without a light. The truth is, it was a great source of discomfort to him. At sunset he was in total darkness in his cave. During the day light enough streamed in from the open doorway. To be alone in total darkness is not pleasant. "If I only had fire!" he said again and again.
