would outmatch yours, but, though I put every ounce into the engine, I was hopelessly out of it. It hadn’t been tuned up well.” “That’s curious, Roseye,” I replied. “I had no idea that my bus was any match for his! I thought that his Mertonville machine was much faster than mine—or than yours as a matter of fact.” “To-day mine is out of the running,” she laughed. To you, my reader, I suppose I ought to describe my own beloved Roseye. Well, I am not good at describing women. As the only son of a blunt, white-haired physician who having made expert study of all the thousand-and-one ailments of the eternal feminine, including that affection called “nerves”—mostly the result of the drug habit, I had heard, from my youth upwards, many disparaging remarks upon the follies and the unbalance of the mind of the gentler sex. This, however, did not prevent me from loving Roseye Lethmere, daughter of Sir Herbert, who had come into my life quite unexpectedly a year ago.

Three times had she flown across the Channel with me, and three times had we returned in safety to Hendon. Indeed, only a week before, she had flown by herself on a British-built Duperdussin with 100 horse-power Anzani engines from Brooklands across to France, descending a mile outside Abbeville. She had had lunch at the old Tête de Boeuf hotel in that town, and returned, landing safely at Hendon—a feat that no woman had ever before accomplished. Roseye Lethmere certainly possessed a character that was all her own. In her ordinary costume, as a London girl, she was
