All the seamen who work on cargo vessels, and on passenger vessels, too, are divided up the same way into the deck department, the engine department and the steward’s department.
As the great engine deep down in Jim’s ship pushes her through the calm blue water of the Mediterranean Sea, he stands watch in the bow. Now he begins to catch sight of small sailing vessels. When his ship enters the port of Alexandria at the mouth of the Nile River in Egypt, he is close to the place where much of the story of ships began.
PAPYRUS REED CANOE. The people of Egypt discovered long ago that bundles of papyrus reed would hold up a man’s weight in the water. Later, they tied the bundles into a canoe shape which was easy to handle.
EGYPTIAN DUGOUT. A log hollowed out in the shape of a reed canoe was stronger, and it lasted longer. By adding boards to a dugout along the top of each side, Egyptians had a vessel that could carry bigger loads. Paddles and their own muscles were all they had for power.
EGYPTIAN SAILING VESSEL. Here the power of wind was added to the power of oarsmen. Luckily the winds of Egypt blew from north to south and helped push sailing vessels up the Nile.
GALLEYS. Greeks and Romans used sail-and-oar vessels called galleys. Slaves, chained to their seats, rowed in rhythm. There were many slaves, so their masters could get extra muscle-power by seating two, three or more banks of oarsmen on each side. A ship with two banks was a bireme; with three, a trireme.
DHOW. Other people around the Mediterranean Sea discovered they could do away with oarsmen by making better use of windpower. They invented triangular sails called lateen sails to take the place of square ones. Lateen-rigged dhows are still used. Columbus had both square and lateen sails on the Santa Maria. All three of his ships together were not as long as Jim’s freighter.
