Deer, bear, beavers, and wolves travel because they need to do so, or for the fun of it. Deer shift for miles from a summer to a winter range, travelling a regular migration route. A number of enemy wolves may follow this moving food supply. Beavers may be seeking a home in new scenes and a bear may be off on an adventure. Wild life trails were worn by generation after generation of wild animals using the same route, the line of least resistance long followed from one territory to another. Trampling feet assisted by wind and water maintained a plain trail. Indian trails often were wild life trails. Stretches of buffalo trails on the plains and bear trails in Alaska were abandoned because so deeply worn and washed. From a low cliff by a mountain stream I watched the wild life along the trail on the other side of the stream. The cañon was wooded but the trail immediately opposite was in the open. Two packs of wolves met on the trail across the river. The leaders rushed to grips and a general mix-up was on. But this was surprisingly brief. There was an outburst of snarling and the gangs passed with but little loss of time and with but one limping. Often as these travellers passed out of sight after a meeting I wondered what and when would be their next adventure. Around a turn of the trail within five minutes after the black bear met the skunk he clashed with a lion, so tracks by the trail showed. I often wondered, too, what experience an animal had been through immediately before he trailed into my sight. The peevish lion was just from her fat, safe, happy kittens. One of the two cross grizzlies was from a row with another grizzly, while the other had been playing along the trail and was on good terms with himself and the world. When skunk and mink--the more offensive of the smelly family--meet in contest, then smells to heaven their meeting. Driven into a corner, the mink will spread high-power musk in the only avenue of advance. He then is in an impregnable position--no fellow has nose sufficiently strong to pass. Or, if the mink place a guarding circle of musk around a prize kill this makes a time lock and will hold his prize for hours against all comers. A skunk and mink clashed by the trail across the river. The skunk was leisurely advancing to seize a flopping, misguided trout on the bank when a mink rushed as though to close with the skunk. The skunk hesitated--and lost the fish. The mink in the delay of action made musk screen near the trout. The skunk went into action and drove the mink off with vile skunk spray. The musk of mink caused his advance to pause, he edged around to the other side, but too much, gave up the fish, and walked off gritting his teeth.
