THE NILE EXPEDITION.

[Illustration: WHALER GIG FOR THE NILE.]

As soon as the authorities had finally made up their minds to send a

flotilla of boats to Cairo for the relief of Khartoum, not a moment was

lost in issuing orders to the different shipbuilding contractors for the

completion, with the utmost dispatch, of the 400 "whaler-gigs" for service

on the Nile. They are light-looking boats, built of white pine, and weigh

each about 920 lb., that is without the gear, and are supposed to carry

four tons of provisions, ammunition, and camp appliances, the food being

sufficient for 100 days. The crew will number twelve men, soldiers and

sailors, the former rowing, while the latter (two) will attend the helm.

Each boat will be fitted with two lug sails, which can be worked reefed, so

as to permit an awning to be fitted underneath for protection to the men

from the sun. As is well known, the wind blows for two or three months

alternately up and down the Nile, and the authorities expect the flotilla

will have the advantage of a fair wind astern for four or five days at the

least. On approaching the Cataracts, the boats will be transported on

wooden rollers over the sand to the next level for relaunching.
