The art of boat-building spread far and wide from the area of origin. Until recently the Chinese were building junks of the same type as they did four or five hundred years earlier. These junks have been compared by more than one writer to the deep-sea boats of the Egyptian Empire period. The Papuans make "dug-outs" and carve eyes on the prows as did the ancient Egyptians and as do the Maltese, Chinese, &c., in our own day. Even when only partly hollowed, the Papuan boats have perfect balance in the water as soon as they are launched.[52] The Polynesians performed religious ceremonies when cutting down trees and constructing boats.[53] In their incantations, &c., the lore of boat-building was enshrined and handed down. The Polynesian boat was dedicated to the mo-o (dragon-god). We still retain a relic of an ancient religious ceremony when a bottle of wine is broken on the bows of a vessel just as it is being launched.

After the Egyptians were able to secure supplies of cedar wood from the Atlas Mountains or Lebanon, by drifting rafts of lashed trees along the coast line, they made dug-out vessels of various shapes, as can be seen in the tomb pictures of the Old Kingdom period. These dug-outs were apparently modelled on the earlier papyri and skin boats. A ship with a square sail spread to the wind is depicted on an Ancient Egyptian two-handed jar in the British Museum, which is of pre-dynastic age and may date to anything like 4000 or 5000 b.c. At that remote period the art of navigation was already well advanced, no doubt on account of the experience gained on the calm waters of the Nile.

(a) Sketch of a boat from Victoria Nyanza, after the drawing in Sir Henry Stanley's Darkest Africa. Only the handles of the oars are shown. In outline the positions of some of the oarsmen are roughly represented.

(b) Crude drawing of a similar boat carved upon the rocks in Sweden during the Early Bronze Age, after Montelius. By comparison with (a) it will be seen that the vertical projections were probably intended to represent the oarsmen.

The upturned hook-like appendage at the stern is found in ancient Egyptian and Mediterranean ships, but is absent in the modern African vessel shown in (a).

These figures are taken from Elliot Smith's Ancient Mariners (1918).

The existence of these boats on the Nile at a time when great race migrations were in progress may well account for the early appearance of dug-outs in Northern Europe. One of the Clyde canoes, found embedded in Clyde silt twenty-five feet above the present sea-level, was found to have a plug of cork which could only have come from the area in which cork trees grow—Spain, Southern France, or Italy.[54] It may have been manned by the Azilians of Spain whose rock paintings date from the Transition period. Similar striking evidence of the drift of culture from the Mediterranean area towards Northern Europe is obtained from some of the rock paintings and carvings of Sweden. Among the canoes depicted are some with distinct Mediterranean characteristics. One at Tegneby in Bohuslän bears a striking resemblance to a boat seen by Sir Henry Stanley on Lake Victoria Nyanza. It seems undoubted that the designs are of common origin, although separated not only by centuries but by barriers of mountain, desert, and sea extending many hundreds of miles. From the Maglemosian boat the Viking ship was ultimately developed; the unprogressive Victoria Nyanza boatbuilders continued through the Ages repeating the design adopted by their remote ancestors. In both vessels the keel projects forward, and the figure-head is that of a goat or ram. The northern vessel has the characteristic inward curving stern of ancient Egyptian ships. As the rock on which it was carved is situated in a metal-yielding area, the probability is that this type of vessel is a relic of the visits paid by searchers for metals in ancient times, who established colonies of dark miners among the fair Northerners and introduced the elements of southern culture.

The ancient boats found in Scotland are of a variety of types. One of those at Glasgow lay, when discovered, nearly vertical, with prow uppermost as if it had foundered; it had been built "of several pieces of oak, though without ribs". Another had the remains of an outrigger attached to it: beside another, which had been partly hollowed by fire, lay two planks that appear to have been wash-boards like those on a Sussex dug-out. A Clyde clinker-built boat, eighteen feet long, had a keel and a base of oak to which ribs had been attached. An interesting find at Kinaven in Aberdeenshire, several miles distant from the Ythan, a famous pearling river, was a dug-out eleven feet long, and about four feet broad. It lay embedded at the head of a small ravine in five feet of peat which appears to have been the bed of an ancient lake. Near it were the stumps of big oaks, apparently of the Upper Forestian period.
