Other minerals.Some old workings of gold and other minerals in the Tagale country have recently been explored, but the result has been unsatisfactory, and the gold appears to have been worked out. There may be other minerals in the country, but no details are known regarding them.
Gum.The best gum comes from the grey acacia, called hashab. This is found between the parallels of 13° and 14°, but is little worked west of El Obeid, on account of the cost of carriage to Khartoum. The chief places where it is collected are El Obeid, Taiara, Bint Joda, Gedid, Um Dam, and Nahud, whence it is either taken by camel straight to Khartoum or to the river at El Dueim or Goz Abu Guma, and there put into boats. The cultivation is simple. In January strips of bark are torn off the trees, dead branches cut away, and, in well managed gardens, the grass is cut as protection from fire. This should always be done, as fires, both accidental and incendiary, are by no means uncommon. As soon as the hot weather comes on, the sap runs up the tree and oozes out of the wound and the tree comes into leaf. This “garden” (geneina) gum is collected every few days and taken into the nearest market. As soon as the rains commence the flow of gum ceases. Wild gum (wadi) is also collected by people who do not own gardens, from the ownerless and, as it were, wild trees, but it is worth comparatively little.
The forests south of the Khor Abu Habl are full of red gum acacias (talh), but the trees are not worked, as the gum is of little value compared with the hashab which abounds. The latter is not yet worked to more than half its capacity, even in Eastern Kordofan.
The following table shows the amount of gum, in hundredweights, exported from the Sudan, most of which comes from Kordofan, but it is impossible to say exactly what proportion:—
| Year. | Cwts. |
|---|---|
| 1879 | 144,706 |
| 1880 | 135,646 |
| 1881 | 150,861 |
| 1899 | 41,963 |
| 1900 | 60,912 |
| 1901 | 170,781 |
| 1902 | 220,000 |
| 1903 | 191,214[116] |
Ostrich feathers.The chief market for ostrich feathers is at El Nahud, where considerable quantities are collected. The best come from Dar El Zeiah in Northern Darfur, but few of these come into the market. The Hamar Arabs keep a few birds in pens. Ostriches have been seen within a few miles of El Obeid. Ostrich farming on a large scale has been proposed, but would be difficult on account of the expense of obtaining food. Feathers from wild birds (Kitala) are longer and more valuable than those plucked from farm birds (Maata), which, though cleaner, are shorter and cheaper.
Ivory.The trade in ivory was never very large, and had in 1901 practically ceased. It is now, however, increasing rapidly, owing to Government restrictions being removed. Over 50,000 lbs. weight passed through Nahud in 1903.
India-rubber.Large quantities of india-rubber might be collected from the country south of El Eddaiya if the cost of transport to Khartoum admitted of a fair price being paid for its collection. At present it does not.
Cattle.There is a large export of cattle, mostly to Omdurman.
Imports.The imports consist chiefly of cotton goods, sugar, salt, soap, tobacco, beads and metal goods, such as axes, hoes, and fasses. Blue and white cottons and muslins, with open-work pattern, are chiefly in demand, but coloured goods are frequently asked for now that the sartorial regulations of the Khalifa are no longer in force. The blacks especially like striking colours, but the dyes must be fast to stand washing with mud and water when no soap is available.
