These people were great workers in wood and stone. They worshipped the Sun, and built a temple to him of huge upright stones, set in a wide circle, with a flat altar stone in the middle, on which they placed their offerings of meat and fish. These offerings they burnt with fire, because the priests of the temple told them it pleased the Sun to smell the smoke of the burning flesh as it rose up in the sky. Twice in the year they had great feasts. One was when the days began to get longer, in the spring, and fruits and flowers began to grow. This time is in March, and we call it the vernal equinox, because then the days and nights are of equal length, and equinox means equal nights. From then on, until June, the days grow longer and the nights grow shorter. From June till September, the nights grow longer and the days shorter, until once more they are the same length, and this is called the autumnal equinox. Then the island tribe held another festival, the feast of the harvest. After that the nights began to grow still longer, and the days shorter, because the sun was going away from them more and more, all through the cold winter. Even to-day we remember these two festivals, by offerings of flowers in the spring, at Easter time, and by the harvest feasts which country people still hold in some places at the end of the summer, when the harvests are gathered in. The island people built their houses and temples of stone. With wood they at first made only roofs and doors, but it was not long before they began to use it for building other things, such as boats. They found no big trees of soft wood on the rocky hillsides, out of which they could make large canoes. So they hewed planks out of the smaller trees, and built the first wooden ships made by man. They could not be called ships, at first, for they were only small boats, but as time went on they built them larger and larger until they would carry forty or fifty men. Modor was the first man to build one of these boats and he was a skilful carpenter. He hewed a long heavy keel for his boat out of a tree trunk, and at each end he set up a stout post, one for the stem, the other for the stern. Wooden braces, or knees, as they are called, fastened by pegs, held the posts to the keel. Modor's tools were heavy stone axes, wedges of stone to split planks with, saws, made of jagged, toothed pieces of flint, with wooden handles bound to them, sharp flint knives for making wooden pegs, and drills, for boring holes for the pegs. With such rough tools it was not easy for Modor and his companions to build a boat, but they were strong and patient, and worked very hard.
