At last the friends who had come down to see them off had taken their leave, and the gang-plank was drawn in, the sails unfurled, and two of the men seized a couple of big oars and pushed off the prow from the bank. Slowly the dahabeah swung over to the middle of the stream; the crowd on shore shouted a last farewell; the breeze caught and filled the big sails, and in a few minutes they were gliding swiftly through the muddy brown water of the Nile, up river toward the very heart of the "dark continent" of Africa.

On the upper deck Mustapha had just put two long wicker chairs for the "Effendis," and Uncle Ben, who had picked up a little Arabic, was comfortably stretched out in one trying to talk with the reis, who sat beside him on a rug spread on the deck smoking his big "hubble-bubble" pipe, every once in awhile giving an order to one of the crew as they trimmed the sails to catch all the breeze.

Mats were spread on the decks for the others; the children, however, were too busy to think of sitting down; they kept running from one side to the other, watching the houses and people on the banks as they slipped past, and the queer craft going and coming on the river.

"There come three nuggars," said Abdal, pointing to three broad, flat, barge-like boats, each with a high lateen sail, coming slowly toward them.

"What a funny name! what are 'nuggars'?" asked George.

"Nuggars are the great Nile cargo boats which carry all kinds of merchandise up and down the river," said Nabul. "See the great boxes and bales on that one," he continued.

"And the one behind has a lot of oxen and sheep on it; they are loaded down to the water's edge, I wonder they don't sink," said George. "Oh! And here come three haystacks floating down-stream! With sails on top of them, too!" he cried.

But no, they too were boats, this time loaded with fodder and the long green bamboos which were being carried to the city. Then a ferryboat filled with people and donkeys crossed the river ahead of them, rowed by men in dark blue cotton gowns. It was all so novel and amusing the children were almost sorry to stop looking in order to eat lunch, though George did say he was hungry enough to eat a hippopotamus.

One of the men brought a table and noiselessly set it on deck for the "Effendis," and then served them the nice things that Mizram had cooked. There was chicken with a nice hot pepper sauce and rice and all kinds of vegetables and melons and dates and oranges.

At the other end of the deck the reis and his family and Mustapha had their meal. Mizram served them all sorts of queer dishes that the little Egyptians kept on bringing to the "Effendi" to taste; and how they laughed at the faces the little American made over some of them!
