The principal cultivation is the dura crop, raised on the land flooded[52] by the Gash. This dura is a large white species called “Taulib,” and is harvested about January; it ranks in quality with the best “Mugad” dura of the Nile. At present the system of irrigation on the Gash is very primitive and wasteful. An improved scheme in accordance with modern ideas is under consideration.[53] A subsidiary rain crop (Naggad), harvested at the end of October, is also raised, but is not of much account. Crops are very liable to the attacks of extraordinary flights of very voracious small birds and also locusts. A very destructive species of “blight” occasionally devastates the crops. It is known as “El Asal” (Aphis Sorghi, vide “Report of Wellcome Research Laboratories—Gordon College—1904”). The rains are often barely sufficient to raise those crops dependent on them. Gardens irrigated by sagias and wells are numerous.
Rains.The rainfall of an average year is very meagre.[54] During the Kharif, the period from June to October, rain of any kind rarely falls on more than 20 to 30 days. On perhaps half a dozen of these there may be very heavy thunderstorms. Rain, which almost invariably comes from the east, generally falls between 6 and 8 p.m., and is preceded by a wind of hurricane force, which usually brings with it a phenomenal wall of dust several thousand feet high and many miles in extent, which often takes an hour or more to blow past, during which time the obscurity and colour of the atmosphere reminds one strangely of the thickest of London fogs.
Climate.The climate for eight months of the year, though hot in March, April, and May, when the thermometer not infrequently registers over 112° Fahr., is healthy. From July to October there is a good deal of malaria, especially during a favourable rainy season. This has been reduced a good deal recently by draining, and precautions against mosquitoes.
Trade.The trade at present is not to be compared with that before the Mahdia, but is increasing; what export trade there is, comes from Gedaref. The imports viâ Suakin and Massawa are not of much importance at present; they are sugar and Manchester goods principally. By far the largest proportion of imports now comes viâ Suakin.
Transport animals.The camel is the best animal for this district, both for riding and transport purposes. A good camel costs from £E.7 to £E.10. They are nearly always available for sale or hire, though in the rains they are not to be found in the immediate vicinity of Kassala.
Horses or mules, which are imported in small numbers from Eritrea or Abyssinia, cannot usually be hired or purchased. Horses are liable to be attacked by a species of horse sickness, which often ends fatally. The Abyssinian and Dongolawi breeds do best. A good riding mule costs from £E.6 to £E.8.
Posts and telegraphs.There is a weekly camel post for both letters and parcels to and from Berber, also a weekly mail to and from Keren and Massawa, also a fortnightly mail to and from Suakin, and a weekly mail to Gedaref and Gallabat. Telegraph lines connect with Suakin, Gedaref, Gallabat, Massaua, and Addis Ababa. Communication is liable to occasional interruptions during the rains.
Serut fly.During the “Kharif” the whole country south of the line Kassala-Asubri swarms with a wasp-like “Serut” fly, which bursts into life as soon as the young grass has sprouted and dies as the vegetation dries up at the end of the rains. This fly is most vehement in its attacks on all animals, including game, but camels suffer the most, and if exposed for any length of time to their bites, they rapidly lose condition, and will probably die from the effects.
Game.In various parts of the districts, described in Section 4, the following varieties are found:—Elephant, rhinoceros, buffalo, giraffe, roan-antelope, kudu, waterbuck, tora hartebeeste, ibex, wild sheep (?), bushbuck (two (?) varieties), reedbuck (scarce); Abyssinian duiker, oribi, dig-dig, and the following gazelles:—Sommering’s, Dorcas, Heuglin’s, Isabella, and possibly Rufifrons; also hippopotamus, crocodile, turtle, warthog, pig, wild ass, lion, leopard, hyena (two varieties), cheetah, serval; also various civet and wild cats, hares, wild dogs, baboons, and monkeys; ostrich, bustard, guinea fowl, francolin, sand grouse, geese, snipe, wild fowl, and quail.
Both rhinoceros and buffalo are rare.
