and weary camels rested and slept after their toils, the voice of Adellan rose sweet and solemn in the loneliness of the desert, holding communion with the high and holy One who inhabiteth eternity. There was a boy among the negro attendants, who was the object of Adellan's peculiar kindness. He seemed feeble and incapable of bearing long fatigue, and at the commencement of the journey Adellan urged him to stay behind, but he expressed so strong a desire to follow the good missionary, he could not refuse his request. He wore his face muffled in a handkerchief, on account of some natural deformity, a circumstance which exposed him to the derision of his fellow slaves, but which only excited the sympathy of the compassionate Adellan. Often, when the boy, panting and exhausted, would throw himself for breath on the hot sand, Adellan placed him on his own camel and compelled him to ride. And when they rested at night, and Adellan thought every one but himself wrapped in slumber, he would steal towards him, and ask him to tell him something out of God's book, that he, Adellan, had been reading. It was a delightful task to Adellan to pour the light of divine truth into the dark mind of this poor negro boy, and every moment he could spare from his friends was devoted to his instruction. One evening, after a day of unusual toil and exertion, they reached one of those verdant spots, called the Oases of the desert; and sweet to the weary travellers was the fragrance and coolness of this green resting-place. They made their tent under the boughs of the flowering acacia, whose pure white blossoms diffused their odours even over the sandy waste they had passed. The date tree, too, was blooming luxuriantly there, and, more delicious than all, the waters of a fountain, gushing out of the rock, reminded them how God had provided for the wants of his ancient people in the wilderness. The missionary and his wife were able to lift their languid heads, and drink in the freshness of the balmy atmosphere. All seemed invigorated and revived but the negro boy, who lay drooping on the ground, and refused the nourishment which the others eagerly shared.
