effect in sailing, that whereas the bed of the Nile, when the water grows low, is full of sand banks under water, the keel under the stem, where the curve is greatest, first strikes upon these banks, and is fast, but the rest of the ship is afloat; so that by the help of oars, and assistance of the stream, furling the sails, you get easily off; whereas, was the keel straight, and the vessel going with the pressure of that immense main-sail, you would be so fast upon the bank as to lie there like a wreck for ever.
This yard and sail is never lowered. The sailors climb and furl it as it stands. When they shift the sail, they do it with a thick stick like a quarter staff, which they call a noboot, put between the lashing of the yard and the sail; they then twist this stick round till the sail and yard turn over to the side required.
When I say the yard and sail are never lowered, I mean while we are getting up the stream, before the wind; for, otherwise, when the vessel returns, they take out the mast, lay down the yards, and put by their sails, so that the boat descends like a wreck broadside forwards; otherwise, being so heavy a-loft, were she to touch with her stem going down the stream, she could not fail to carry away her masts, and perhaps be staved to pieces.
The cabin has a very decent and agreeable dining-room about twenty feet square, with windows that have close and latticed shutters, so that you may open them at will in the day-time, and enjoy the freshness of the air; but great care must be taken to keep these shut at night.
