'Only the fear of the shovel and the wrench kept me from shaking hands with both men at this discovery. But I beamed at them; and they at me. I was enjoying it. The unwonted jar beneath my feet was wrinkling my diaphragm with spasms of delight. And the fireman beamed at the engineer, with a look that said, "See the lunatic grin; he likes it!"
'He did like it. How the iron wheels sang to me as they took the rails! How the rushing wind in my ears sang to me! From my stand on the fireman's side of the cab I could catch a glimpse of the track just ahead of the engine, where the ties seemed to leap into the throat of the mile-devouring monster. The joy of it! of seeing space swallowed by the mile!
'I shifted the eggs from hand to hand and thought of my horse, of Agassiz, of the great book, of my great luck,--luck,--luck,--until the multitudinous tongues of the thundering train were all chiming "luck! luck! luck!" They knew! they understood! This beast of fire and tireless wheels was doing its very best to get the eggs to Agassiz!
'We swung out past the Blue Hills, and yonder flashed the morning sun from the towering dome of the State House. I might have leaped from the cab and run the rest of the way on foot, had I not caught the eye of the engineer watching me narrowly. I was not in Boston yet, nor in Cambridge either. I was an escaped lunatic, who had held up a train, and forced it to carry me to Boston.
'Perhaps I had overdone the lunacy business. Suppose these two men should take it into their heads to turn me over to the police, whether I would or no? I could never explain the case in time to get the eggs to Agassiz. I looked at my watch. There were still a few minutes left, in which I might explain to these men, who, all at once, had become my captors. But it was too late. Nothing could avail against my actions, my appearance, and my little pail of sand.
'I had not thought of my appearance before. Here I was, face and clothes caked with yellow mud, my hair wild and matted, my hat gone, and in my full-grown hands a tiny tin pail of sand, as if I had been digging all night with a tiny, tin shovel on the shore! And thus to appear in the decent streets of Boston of a Sunday morning!
