The frieze now was more grotesque than ever, but had changed suddenly to an equestrian one, sharply outlined against the deep-blue Egyptian sky.  Those who have never ridden before have to ride in Egypt, and when the donkeys break into a canter, and the Nile Irregulars are at full charge, such a scene of flying veils, clutching hands, huddled swaying figures, and anxious faces is nowhere to be seen.  Belmont, his square figure balanced upon a small white donkey, was waving his hat to his wife, who had come out upon the saloon-deck of the Korosko.  Cochrane sat very erect with a stiff military seat, hands low, head high, and heels down, while beside him rode the young Oxford man, looking about him with drooping eyelids as if he thought the desert hardly respectable, and had his doubts about the Universe.  Behind them the whole party was strung along the bank in varying stages of jolting and discomfort, a brown-faced, noisy donkey-boy running after each donkey.  Looking back, they could see the little lead-coloured stern-wheeler, with the gleam of Mrs. Belmont’s handkerchief from the deck.  Beyond ran the broad, brown river, winding down in long curves to where, five miles off, the square, white block-houses upon the black, ragged hills marked the outskirts of Wady Halfa, which had been their starting-point that morning.

“Isn’t it just too lovely for anything?” cried Sadie joyously.  “I’ve got a donkey that runs on casters, and the saddle is just elegant.  Did you ever see anything so cunning as these beads and things round his neck?  You must make a memo. re donkey, Mr. Stephens.  Isn’t that correct legal English?”

Stephens looked at the pretty, animated, boyish face looking up at him from under the coquettish straw hat, and he wished that he had the courage to tell her in her own language that she was just too sweet for anything.  But he feared above all things lest he should offend her, and so put an end to their present pleasant intimacy.  So his compliment dwindled into a smile.

“You look very happy,” said he.

“Well, who could help feeling good with this dry, clear air, and the blue sky, and the crisp yellow sand, and a superb donkey to carry you?  I’ve just got everything in the world to make me happy.”

“Everything?”

“Well, everything I have any use for just now.”

“I suppose you never know what it is to be sad?”

“Oh, when I am miserable, I am just too miserable for words.  I’ve sat and cried for days and days at Smith’s College, and the other girls were just crazy to know what I was crying about, and guessing what the reason was that I wouldn’t tell them, when all the time the real true reason was that I didn’t know myself.  You know how it comes like a great dark shadow over you, and you don’t know why or wherefore, but you’ve just got to settle down to it and be miserable.”

“But you never had any real cause?”
