"Just take a squint at them valves, will you?--ever seen anything like 'em before? Of course you haven't. Don't look like valves, eh? Can you break 'em, can you warp 'em, can you pit 'em? D'ye twig how the mixture reaches the cylinder? None of your shoulders or kinks to choke it up--is there?--and the same with the exhaust. Would you ever have a mushroom valve again after you've once cast your peepers over this arrangement? Now, if I took up areonotting--if _I_ wanted to fly the Channel----" He stopped abruptly, having seen his master standing in the open doorway. "By gad, Dale," cried Medenham, "I have never heard your tongue wagging in that fashion before." Dale was flustered. "Beg pardon, my lord, but I was only----" he began. "Only using the cut-out, I fancy. Come here, I want you a minute." The other chauffeurs suddenly discovered that they had urgent business elsewhere. They vanished.

Dale's blunder was almost irreparable, yet he could not find it in his heart to blame the man for being an enthusiast. "You have put me in a deuce of a fix," he said at last. "This Frenchman is acquainted with Miss Vanrenen. He knows she is here, and will probably see her off in the morning. If his chauffeur recognizes the car he will be sure to speak of it. That gives the whole show away." "I'm very sorry, my lord----" "Dash it all, there you go again. But it is largely my own fault. I ought to have warned you, though I little expected this sort of a mix-up. In future, Dale, while this trip lasts, you must forget
