"I was saying that the present-day world slant is sanely skeptical—as it should be," Brouillard went on at the end of the thoughtful pause. "Being modern and reasonably sophisticated, we can smile at the signs and omens of the ages that had to get along without laboratories and testing plants. Just the same, every man has his little atavistic streak, if you can hit upon it. For example, you may throw flip-flaps and call it rank superstition if you like, but I have never been able to get rid of the notion that birthdays are like the equinoxes—turning-points in the small, self-centred system which we call life."
"Poodle-dogs!" snorted the one whose attitude was both jocose and analytical, stuffing more of the spruce branches under his head to keep the pipe ashes from falling into his eyes.
"I know; being my peculiar weakness instead of your own, it's tommy-rot to you," Brouillard rejoined good-naturedly. "As I said a few minutes ago, I am only burbling to hear the sound of my own voice. But the bottoming fact remains. You give a screw twist to a child's mind, and if the mind of the man doesn't exhibit the same helical curve——"
"Suppose you climb down out of the high-browed altitudes and give it a plain, every-day name?" grumbled the staff authority on watersheds.
"It's casting pearls before swine, but you're a pretty good sort of swine, Grizzy. If you'll promise to keep your feet out of the trough, I'll tell you. Away back in the porringer period, in which we are all like the pin-feathered dicky-birds, open-mouthed for anything anybody may drop into us, some one fed me with the number seven."
"Succulent morsel!" chuckled Grislow. "Did it agree with you?"
Brouillard sat back from the fire and clasped his hands over his bent knees. He was of a type rare enough to be noteworthy in a race which has drawn so heavily upon the Anglo-Saxon and Teutonic stocks for its build and coloring: a well-knit figure of a man, rather under than over the normal stature, but bulging athletically in the loose-fitting khaki of the engineer; dark of skin, even where the sun had not burned its rich mahogany into the olive, and owning a face which, with the upcurled mustaches, the brooding black eyes, and the pure Gallic outline of brow and jaw, might have served as a model for a Vierge study of a fighting franc-tireur.
"I don't remember how early in the game the thing began," he resumed, ignoring Grislow's joking interruption, "but away back in the dimmest dawnings the number seven began to have a curious significance for me. From my earliest recollections things have been constantly associating themselves with seven or some multiple of it. You don't believe it, of course; but it is true."
"Which means that you have been sitting up and taking notice when the coincidences hit, and have forgotten the millions of times when they didn't," scoffed the listener.
"Probably," was the ready admission. "We all do that. But there is one set of 'coincidences,' as you call them, that can't be so easily turned down. Back in the pin-feather time that I mentioned somebody handed me a fact—the discovery of the physiologists about the waste and replacement that goes on in the human organism, bringing around a complete cellular change about once in every seven years. Are you asleep?"
