startling: dry as the finest champagne, almost fiercely pure and fresh, exhilarating—well, too exhilarating for certain people."

The doctor nodded.

"Champagne goes very quickly to some heads," he interjected.

"Beni-Kouidar has nothing to say to modern civilisation. It is a wild and turbulent city, divided into quarters—the Arab quarter, the Jews' quarter, the freed negroes' quarter, and so on—and furthermore, is infested at certain seasons by the Sahara nomads, who camp in filthy tents on the huge sand dunes round about, and sell rugs, burnouses, and Touareg work to the inhabitants, buying in return the dates for which the palms of Beni-Kouidar are celebrated.

"I wanted to see a real Sahara city to which the Cook's tourist had not as yet penetrated, and I resolved to ride there from Beni-Mora. When Henry Marnier heard of it he asked if he might accompany me.

"Marnier was a young man who had recently left Oxford, and who had come out to Beni-Mora only a week before to see his mother, who was going through the sulphur cure. He was what is generally called a 'serious-minded young man'; intellectual, inclined to grave reading and high thinking, totally devoid of frivolity, a little cold in manner and temperament, one would have sworn; in fact, a type of a very well-known kind of Oxford undergraduate, the kind that takes a good tutorship for a year or so after leaving the University, and then becomes a schoolmaster or a clergyman. Marnier, by the way, intended to take orders.

"Now, this sort of young man is not precisely my sort, and especially not my sort in the Sahara Desert. But I did not want to be rude to Marnier, who was friendly and agreeable, and obviously anxious to increase his already considerable store of knowledge. So I put my inclinations in my pocket, and, with inward reluctance, I agreed.

"We set off with Safti, my faithful one-eyed Arab guide, and after three long days of riding and talking—as I had feared—Maeterlink and Tolstoy, Henley and Verlaine (this last being utterly condemned by Marnier as a man of weak character and degraded life) we saw the towers of Beni-Kouidar aspiring above the shifting sands, the tufted summits of the thousands of palm-trees, and heard the dull beating of drums and the cries of people borne to us over the spaces of which silence is the steady guardian.

"We were all pretty tired, but Marnier was, especially done up. He had recently been working very hard for the 'first' with which he had left Oxford, and was not in good condition. We were, therefore, glad enough when we rode through the wide street thronged with natives, turned the corner into the great camel market, and finally dismounted before the door of the one inn, the 'Rendezvous des Amis,' a mean, dusty, one-storey building, on whose dirty white wall was a crude painting of a preposterous harridan in a purple empire gown, pouring wine for a Zouave who was evidently afflicted with elephantiasis. Yet, tired as I was, I stepped out into the camel market for a moment before going into the house, emptied my lungs, and slowly filled them.

"'What air!' I said to Marnier, who had followed me.

"'It is extraordinary,' he answered in his rather dry tenor voice. 'I should say like the best champagne, if I did not happen to be a teetotaller.'

"(The market, I must explain, was not at that moment in active operation.)

"After a bain de siege—we both longed for total immersion—and some weak tea, in which I mingled a spoonful of rum, we felt better, but we reposed till dinner, and once again Marnier, in his habitually restrained and critical manner, discussed contemporary literature, and what Plato and Aristotle, judging by; their writings, would have been likely to think of it. And once again I felt as if I were in the 'High' at Oxford, and was almost inclined to wish that Marnier was the rowdy type of undergrad, who ducks people in water troughs and makes bonfires in quads."

"H'm!" said the doctor gravely. "Better, perhaps, if
