The variety poured through this funnel of the mountains comprised all classes. Professional prospectors with their burros, ready alike for the desert or the most inaccessible crags, were followed by a troupe of college boys afoot leading one or two old mares as baggage transportation. The business-like, semi-military outfits of geological survey parties, the worn but substantial hunters' equipments, the marvellous and oftentimes ridiculous luxury affected by the wealthy camper, the makeshifts of the poorer ranchmen of the valley, out with their entire families and the farm stock for a "real good fish," all these were of never-failing interest to Bob. In fact, he soon discovered that the one absorbing topic--outside of bears, of course--was the discussion, the comparison and the appraising of the various items of camping equipment. He also found each man amusingly partisan for his own. There were schools advocating--heatedly--the merits respectively of the single or double cinch, of the Dutch oven or the reflector, of rawhide or canvas kyacks, of sleeping bags or blankets. Each man had invented some little kink of his own without which he could not possibly exist. Some of these kinks were very handy and deserved universal adoption, such as a small rubber tube with a flattened brass nozzle with which to encourage reluctant fires. Others expressed an individual idiosyncrasy only; as in the case of the man who carried clothes hooks to screw into the trees. A man's method of packing was also closely watched. Each had his own favourite hitch. The strong preponderance seemed to be in favour of the Diamond, both single and double, but many proved strongly addicted to the Lone Packer, or the Basco, or the Miners', or the Square, or even the generally despised Squaw, and would stoutly defend their choices, and give reasons therefore. Bob sometimes amused himself practising these hitches in miniature by means of a string, a bent nail, and two folded handkerchiefs as packs. After many trials, and many lapses of memory, he succeeded on all but the Double Diamond. Although apparently he followed every move, the result was never that beautiful all-over tightening at the last pull. He reluctantly concluded that on this point he must have instruction.
