Then silence descended again, and hours passed in our search for sound or smell of the animal we wished chiefest to find--the giant armadillo. These rare beings have a distinct odor. Months of work in the open had sharpened my nostrils so that on such a tramp as this they were not much inferior to those of Nupee. This sense gave me as keen pleasure as eye or ear, and furnished quite as much information. The odors of city and civilization seemed very far away: gasoline, paint, smoke, perfumery, leather--all these could hardly be recalled. And how absurd seemed society's unwritten taboo on discussion of this admirable, but pitifully degenerate sense! Why may you look at your friend's books, touch his collection of _netsukés_, listen to his music, yet dare sniff at naught but his blossoms! In the open spaces of the earth, and more than anywhere in this conservatory of unblown odors, we come more and more to appreciate and to envy a dog's sensitive muzzle. Here we sniffed as naturally as we turned ear, and were able to recognize many of our nasal impressions, and even to follow a particularly strong scent to its source. Few yards of trail but had their distinguishable scent, whether violent, acrid smell or delectable fragrance. Long after a crab-jackal had passed, we noted the stinging, bitter taint in the air, and now and then the pungent wake of some big jungle-bug struck us like a tangible barrier. The most tantalizing odors were the wonderfully delicate and penetrating ones from some great burst of blossoms, odors heavy with sweetness, which seeped down from vine or tree high overhead, wholly invisible from below even in broad daylight. These odors remained longest in memory, perhaps because they were so completely the product of a single sense. There were others too, which were unforgetable, because, like the voice of the frog, they stirred the memory a fraction before they excited curiosity. Such I found the powerful musk from the bed of leaves which a fawn had just left. For some reason this brought vividly to mind the fearful compound of smells arising from the decks of Chinese junks. Along the moonlit trail there came wavering whiffs of orchids, ranging from attar of roses and carnations to the pungence of carrion, the latter doubtless distilled from as delicate and beautiful blossoms as the former. There were, besides, the myriad and bewildering smells of sap, crushed leaves, and decaying wood; acrid, sweet, spicy and suffocating, some like musty books, others recalling the paint on the Noah's Ark of one's nursery.
