of Bahr el Ghazal and El Arab. 37 Judging from the accounts of travellers who have crossed these and other rivers in the country at certain points, they are mostly fordable during the dry season, and in flood time are from 6 to 20 feet deep. They seem to be full of fish at all times. Some of the beds are as much as 250 yards broad.

Dr. Junker found that the Rohl, Jau (Ayel), and Tonj were easily fordable in July and August, but that the Jur (or Geddi), having a deeper bed and a less-defined trough than the others, was, in the neighbourhood of Wau, in the middle of August, 10 feet deep, with banks 15 to 20 feet high, and a breadth of 230 yards. A native ferryboat holding 35 men was here available. The Wau River, traversed a few days later, was very similar, but rather deeper. The banks of the Jur and Wau are heavily wooded. The water is greenish-yellow, but good.
