There lay the dark fuel, and here ran the tunnel into the foot of the hill whence came the coal. Of course, wanting to see it all, we determined to explore the thing to our satisfaction. The tunnel being but three feet wide by three and a half high, we were obliged to stoop very low. Onward we went, bold as the lion in his cave, lightly talking of the great dampness and the little car-track that wound its way so far into the bowels of the earth, etc., etc., until we found ourselves about fifty yards from the daylight door. Here a slight caving from the side of the passage caused a panic in a party of three, and for some minutes the bowels of Vesuvius never knew a greater rumbling than was heard in the tunnel of that coal-mine. When the weakest,--who had been trampled into the mud by the stampede,--had once more dragged himself into daylight, we concluded that we knew _all about_ coal-mines, and thought it not necessary to penetrate any more hills to inform ourselves better. Betaking ourselves to the wagon, we once more resumed our journey. Coming into the splendid city of Indianapolis one bright morning, we were greatly struck with its great life and beauty, and concluded to camp in a pretty grove just back of the great asylum and spend a few days in surveying and acquainting ourselves with the Hoosier capital. The first was reception-day for the horse-traders, who swarmed to us from all directions. They were all good, clever fellows, and offered us a chance to make fifty dollars in a single swap. The boys wanted to trade, but I had conscientious _scruples_ against taking the advantage of such good-hearted, honest fellows, and prevailed on the boys to deal gently with the innocent. The great clouds of dark smoke that curl from the engines of the thirteen railroads, the deafening sound of the car-bells at train-time, together with a depot that is surpassed in size and magnificence by but one or two in the United States, speak the advantages of this thriving and lovely city. Its court-house is also a model, being one of the finest in the land. Having informed ourselves to our satisfaction, we again pulled out.
