No sooner was the bustle of arrangement completed than a gray 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 tools off my cap in respect for their faith, and at the close of their prayer made my salaam to their venerable Faky (priest); he returned the salutation with the cold dignity of an Arab. On the next day my wife's fever was renewed, but she was placed on a dromedary and we reached Cassala about sunset. The place is rich in hyenas, and the night was passed in the discordant howling of these disgusting but useful animals. They are the scavengers of the country, devouring every species of filth and clearing all carrion from the earth. Without the hyenas and vultures the neighborhood of a Nubian village would be unbearable. It is the idle custom of the people to leave unburied all animals that die; thus, among the numerous flocks and herds, the casualties would create a pestilence were it not for the birds and beasts of prey. On the following morning the fever had yielded to quinine, and we were enabled to receive a round of visits--the governor and suite, Elias Bey, the doctor and a friend, and, lastly, Malem Georgis, an elderly Greek merchant, who, with great hospitality, insisted upon our quitting the sultry tent and sharing his own roof. We therefore became his guests in a most comfortable house for some days. Here we discharged our camels, as our Turk, Hadji Achmet's, service ended at this point, and proceeded to start afresh for the Nile tributaries of Abyssinia. CHAPTER II.
