As we approached within about twenty-five miles o Cassala, Iremarked that the country on our left was in many places flooded;the Arabs, who had hitherto been encamped in this neighbourhood during the dry season, were migrating to other localities in the neighbourhood of Soojalup and Gozerajup, with their vast herds of camels and goats. As rain had not fallen in sufficient quantity to account for the flood, I was informed that it was due to the river Gash, or Mareb, which, flowing from Abyssinia, passed beneath the walls of Cassala, and then divided into innumerable ramifications; it was eventually lost, and disappeared in the porous soil, after having flooded a large extent of country. This cause accounted for the never-failing wells of Soojalup--doubtless a substratum of clay prevented the total escape of the water, which remained at a depth of forty feet from the surface. The large tract of country thus annually flooded by the river Gash is rendered extremely fruitful, and is the resort of both the Hadendowa and the Hallonga Arabs during the dry season, who cultivate large quantities of dhurra, and other grain.
Unfortunately, in these climates, fertility of soil is generally combined with unhealthiness, and the commencement of the rainy season is the signal for fevers and other maladies. No sooner had we arrived in the flooded country than my wife was seized with a sudden and severe attack, which necessitated a halt upon the march, as she could no longer sit upon her camel. In the evening, several hundreds of Arabs arrived, and encamped around our fire. It was shortly after sunset, and it was interesting to watch the extreme rapidity with which these swarthy sons of the desert pitched their camp--a hundred fires were quickly blazing;the women prepared the food, children sat in clusters round the blaze, as all were wet from paddling through the puddled ground, from which they were retreating.
No sooner was the bustle of arrangement completed, than a grey old man stepped forward, and, responding to his call, every man of the hundreds present formed in line, three or four deep. At once there was total silence, disturbed only by the crackling of the fires, or by the cry of a child; and with faces turned to the east, in attitudes of profound devotion, the wild but fervent followers of Mahomet repeated their evening prayer.
The flickering red light of the fires illumined the bronze faces of the congregation, and as I stood before the front line of devotees, I took off my cap in respect for their faith, and at the close of their prayer I made my salaam to their venerable Faky (priest); he returned the salutation with the cold dignity of an Arab. In this part the coorbatch of the Turk was unnecessary, and we shortly obtained supplies of milk. I ordered the dragoman Mahomet to inform the Faky that I was a doctor, and that I had the best medicines at the service of the sick, with advice gratis. In a short time I had many applicants, to whom Iserved out a quantity of Holloway's pills. These are most useful to an explorer, as, possessing unmistakeable purgative properties, they create an undeniable effect upon the patient, which satisfies him of their value. They are also extremely convenient, as they may be carried by the pound in a tin box, and served out in infinitesimal doses from one to ten at a time, according to the age of the patients. I had a large medicine chest, with all necessary drugs, but I was sorely troubled by the Arab women, many of whom were barren, who insisted upon my supplying them with some medicine that would remove this stigma and render them fruitful. It was in vain to deny them; Itherefore gave them usually a small dose of ipecacuanha, with the comforting word to an Arab, "Inshallah," "if it please God." At the same time I explained that the medicine was of little value.
