The burning of their town had brought new and fearful suffering on the stricken Memphites, and notwithstanding Katharina’s death the Nile still did not rise.  The Kadi therefore once more summoned a meeting of all the inhabitants from both sides of the river, three days after the interrupted marriage-festival.  It was held under the palms by Nesptah’s inn, and there he proclaimed to the multitude, Moslem and Christian, by means of the Arab herald and Egyptian interpreter, what the Khaliff commanded him to declare, namely:  that God, the One, the All-merciful, scorned human sacrifice.  In this firm conviction he, Omar, would beseech Allah the Compassionate, and he sent a letter which was to be cast into the river in his name.

And this letter was addressed: 

“To the River of Egypt.”  And its contents were as follows: 

“If thou, O River, flowest of thyself, then swell not; but if it be God, the One, the Compassionate, that maketh thee to flow, then we entreat the All-merciful that he will bid thee rise!”

“That which is not of God,” wrote Amru in the letter which enclosed Omar’s, “what shall it profit men?  But all things created are by Him, and so is your noble river.  The Most High will hearken to Omar’s prayers and ours, and I therefore command that all of you—­Moslems, Christians, and Jews, shall gather together in the Mosque on the other side of the Nile which I have built to the glory of the All-merciful, and that you there lift up your souls in one great common prayer, to the end that God may hear you and take pity on your sufferings!”

And the Kadi bid all the people to go across the Nile and they obeyed his bidding.  Bishop John called on his clergy and marched at their head, leading the Christians; the priests and elders of the Jews led their people next to the Jacobites; and side by side with these the Moslems gathered in the magnificent pillared sanctuary of Amru, where the three congregations of different creeds lifted up, their hearts and eyes and voices to the pitying Father in Heaven.

And this very Mosque of Amru has more than once been the scene of the same sublime spectacle; even within the lifetime and before the eyes of the narrator of this tale have Moslems, Christians, and Jews united there in one pious prayer, which must have been acceptable indeed in the ears of the Lord.

Not long after the letter from the Khaliff Omar had been cast into the Nile, and the prayer of the united assembly had gone up to Heaven from the Mosque of Armu, a pigeon came in announcing a sudden rise in the waters at the cataracts; and after some still anxious but hopeful days of patience, the Nile swelled higher and yet higher, overflowed its banks, and gave the laborer a right to look forward to a rich harvest; and then, when a heavy storm of rain had laid the choking dust, the plague, too, disappeared.

Just when the river was beginning to rise perceptibly Amru returned; bringing in his train little Mary and Rustem, Philippus the leech and Haschim, who had joined the governor’s caravan at Djidda.
