barriers, what intrigued him most was the conundrum he referred to as the Eye-Nose Paradox, or the Senses Census. Willy was a man, and therefore he relied chiefly on sight to form his understanding of the world. Mr. Bones was a dog, and therefore he was next to blind. His eyes were useful to him only in that they helped to distinguish shapes, to make out the broad outlines of things, to tell him whether the object or being that loomed up before him was a hazard to be shunned or an ally to be kissed. For true knowledge, for a genuine grasp of reality in all its manifold configurations, only the nose was of any value. Whatever Mr. Bones knew of the world, whatever he had discovered in the way of insights or passions or ideas, he had been led to by his sense of smell. At first, Willy could scarcely believe his eyes. The dog’s avidity for smells seemed boundless, and once he had found an odor that interested him, he would clamp his nose over it with such determination, such whole-hog enthusiasm, that everything else in the world would cease to exist. His nostrils were turned into suction tubes, sniffing up scents in the way a vacuum cleaner inhales bits of broken glass, and there were times—many times, in fact—when Willy marveled that the sidewalk did not crack apart from the force and fury of Mr. Bones’s snout-work. Normally the most obliging of creatures, the dog would grow stubborn, distracted, seem to forget his master entirely, and if Willy happened to tug on the leash before Mr. Bones was ready to move on, before he had ingested the full savor of the turd or urine puddle under scrutiny, he would plant his legs to resist the yank, and so unbudgeable did he become, so firmly did he anchor himself to the spot, that Willy often wondered if there wasn’t a sac hidden somewhere in his paws that could secrete glue on command.
How not to be fascinated by all this? A dog had roughly two hundred and twenty million scent receptors, whereas a man had but five million, and with a disparity as great as that, it was logical to assume that the world perceived by a dog was quite different from the one perceived by a man. Logic had never been Willy’s strength, but in this case he was driven by love as much as by intellectual curiosity, and therefore he stuck with the question with more persistence than usual. What did Mr. Bones experience when he smelled something? And, just as important, why did he smell what he smelled? Close observation had led Willy to conclude that there were essentially three categories of interest to Mr. Bones: food, sex, and information about other dogs. A man opens the morning paper to find out what his fellow creatures have been up to; a dog does the same thing with his nose, sniffing trees and lampposts and fireboxes to learn about the doings of the local dog population. Rex, the sharp-fanged Rottweiler, has left his mark on that bush; Molly, the cute cocker spaniel, is in heat; Roger, the mutt, ate something that didn’t agree with him. That much was clear to Willy, a matter beyond dispute. Where things grew complicated was when you tried to understand what the dog was feeling. Was he merely looking out for himself, digesting information in order to keep a leg up on the other dogs, or was there something more to these frantic sniff-fests than simple military tactics? Could pleasure be involved as well? Could a dog with his head buried in a garbage can experience something akin, say, to the heady swoon that comes over a man when he presses his nose against a woman’s neck and breathes in a whiff of ninety-dollar-an-ounce French perfume?
It was impossible to know for sure, but Willy tended to think that he did. Why else would it have been so difficult to wrench Mr. Bones away from the sites of certain smells? The dog was enjoying himself, that’s why. He was in a state of intoxication, lost in a nasal paradise he could not bear to leave. And if, as has already been established, Willy was convinced
