“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.

In the course of their journey they received news of all that had been happening at Memphis, and when the travellers were approaching their last night-quarters, and the Pyramids were already in sight, the governor said to little Mary: 

“What do you say little one?  Do we not owe the Memphites the treat of a splendid marriage festival?”

“No, my lord, two,” replied the child.

“How is that?” laughed Amru, “You are too young and do not count yet, and I know no other maiden in Memphis whose wedding I should care to provide for.”

“But there is a man towards whom you feel most kindly, and who lives as lonely as a recluse.  I should like to see him married, and at the same time as Orion and Paula.  I mean our good friend Philippus.”

“The physician?  And is he still unwed?” asked Amru in surprise; for no Moslem of the leech’s age and position could remain unmarried without exposing himself to the contempt of his fellow-believers.  “He is a widower then!”
