Trade between different tribes must have been greatly facilitated by means of canoes, which Neolithic man knew well how to make. The art of navigation was probably well advanced. The canoes were formed of the trunks of large trees. In most cases they were hollowed out by means of the ax and fire combined. Sometimes the ends were partially rounded or pointed, but often cut nearly square across—rather a difficult shape to propel fast or to guide properly. These ancient boats have been found in nearly all the principal rivers of Europe, and in many cases, no doubt, come down to much later date than the Neolithic Age. From the remains of fish found in their refuse heaps we are confident that in some such a shaped boat as this they trusted themselves far out at sea. They served to transport them from the shores of Europe to England, and at a later date to Ireland. Neolithic Cloth. The clothing of the men of the Neolithic Age doubtless consisted largely of the prepared skins of the animals, and some fragments of leather have been found in the lake settlements. But a very important step in advance was the invention of spinning and weaving, both of which processes were known at this time. The cloth which is here represented is formed of twists of interwoven flax, of rough workmanship, it is true, but none the less remarkable, considering the epoch in which it was manufactured. Balls of thread and twine have also been found.30 This cut is a spindle-whorl. These have been discovered very often. They were made sometimes of stone and at other times of pottery and bone. The threads were made of flax, and the combs which were used for pushing the threads of the warp into the weft show that it was woven into linen on some kind of a loom. Several figures of the loom have been given, but we have no certainty of their correctness.31 Spindle-whorl, and Weaver’s Comb. Let us now see if we can gather anything as to the religious belief of Neolithic man. On this point we can at best only indulge in vague conjectures. Yet some light seems thrown on this difficult subject by examination of the burial mounds. This introduces us to a subject of much interest which, in our hurried review, we can but glance at.
