|Whenever the cares of life weigh too heavily upon me, and the _ennui_ which comes to those who have more wealth than they know what to do with settles down upon me, and I get weary of civilization, I like to load up my narrow-gauge mule Boomerang and take a trip into the mountains. I call my mule Boomerang because I never know where he is going to strike. He is a perpetual surprise to me in this respect. A protracted acquaintance with him, however, has taught me to stand in front of him when I address him, for the recoil of Boomerang is very disastrous. Boomerang is very much below the medium height, with a sad, faraway look in his eye. He has an expression of woe and disappointment and gloom, because life has been to him a series of blasted hopes and shattered ambitions. In his youth he yearned to be the trick-mule of a circus, and though he fitted himself for that profession, he finds himself in the decline of life with his bright anticipations nothing but a vast and robust ruin. About all the relaxation he has is to induce some trusting stranger to caress his favorite chilblain, and then he kicks the confiding stranger so high that he can count the lamp-posts on the streets of the New Jerusalem. When Boomerang and I visit a mining camp the supplies of giant powder and other combustibles are removed to some old shaft and placed under a strong guard. In one or two instances where this precaution was not taken the site of the camp is now a desolate, barren waste, occupied by the prairie-dog and the jack-rabbit. When Boomerang finds a nitro-glycerine can in the heart of a flourishing camp, and has room to throw himself, he can arrange a larger engagement for the coroner than any mule I ever saw. There is a new camp in the valley of the Big Laramie River, near the dividing line between Wyoming and Colorado. A few weeks ago the murmur of the rapid river down the canon and the cheerful solo of the cayote alone were heard. Now several hundred anxious excited miners are prospecting for gold, and the tent-town grows apace. Up and down the sides of the river and over the side of the mountain every little way a notice greets the eye announcing that "the undersigned claim 1,500 feet in length by 300 feet in width upon" the lode known as the Pauper's Dream, or the Blue Tail Fly, or the Blind Tom, or the Captain Kidd, or the Pigeon-Toed Pete, with all the dips, spurs, angles, gold and silver bearing rock or earth therein contained.
