One steamer is for the use of the Mudir, and the other runs a fortnightly service between Dongola and Merowe during low Nile, and from Kerma to Merowe when the river permits.

The river between Kerma and Dongola is always navigable for lightly-loaded steamers, but when the river is low there are one or two dangerous rocky places, and it is not considered advisable to run a regular service. This portion is therefore principally navigated by sailing boats during this period.

Steamers and sailing boats are available for the carriage of private passengers and goods.

The river is only navigable a short distance upstream of Merowe at certain times of the year.

Khartoum and South.

There are three screw and seven stern-wheel armed gun-boats; the latter being frequently used for transport work. The screw boats are kept as station “guard ships” at the southernmost Blue and White Nile posts and at Khartoum. In addition to the gunboats there are five stern-wheel steamers and one new paddle steamer of about 100 to 120 feet long for post, passenger and freight service. For local work or special duty there are four very old paddle steamers of Gordon’s time, two screw tugs, and four launches, as well as 20 barges capable of carrying troops, animals, and freight.

Regular services.[140]A monthly service, 13 days, runs to Gondokoro, the most northerly Nile post of Uganda, leaving Khartoum on the 15th, and returning from Gondokoro for the north about the 29th of each month, arriving at Khartoum about the 10th.

This steamer calls at all intermediate stations south of Goz Abu Guma.

A monthly service (9 days) runs up the Bahr El Ghazal to Wau and Meshra El Rek, or as near as the state of the river will allow, leaving Khartoum on the 1st of each month; starting on the return journey on the 12th, and arriving at Khartoum about the 19th. These steamers also call at all intermediate stations south of Goz Abu Guma.

The weekly service from Khartoum every Tuesday to Goz Abu Guma and intermediate stations, returning on Sundays, is now carried out by the private company below-mentioned.
