“But I had gone; and was ready to drop over the high board-fence, when it occurred to me that I might drop into a policeman’s arms. Hanging my pail in a splint on top of a post, I peered cautiously over--a very wise thing to do before you jump a high board-fence. There, crossing the open square toward the station, was a big burly fellow with a club--looking for me. “I flattened for a moment, when some one in the yard yelled at me. I preferred the policeman, and grabbing my pail I slid over to the street. The policeman moved on past the corner of the station out of sight. The square was free, and yonder stood a cab! “Time was flying now. Here was the last lap. The cabman saw me coming, and squared away. I waved a paper dollar at him, but he only stared the more. A dollar can cover a good deal, but I was too much for one dollar. I pulled out another, thrust them both at him, and dodged into the cab, calling, ‘Cambridge!’ “He would have taken me straight to the police station, had I not said, ‘Harvard College. Professor Agassiz’s house! I’ve got eggs for Agassiz’; and pushed another dollar up at him through the hole. “It was nearly half-past six. “‘Let him go!’ I ordered. ‘Here’s another dollar if you make Agassiz’s house in twenty minutes. Let him out. Never mind the police!’ “He evidently knew the police, or there were few around at that time on a Sunday morning. We went down the sleeping streets, as I had gone down the wood-roads from the pond two hours before, but with the rattle and crash now of a fire brigade. Whirling a corner into Cambridge Street, we took the bridge at a gallop, the driver shouting out something in Hibernian to a pair of waving arms and a belt and brass buttons. “Across the bridge with a rattle and jolt that put the eggs in jeopardy, and on over the cobble-stones, we went. Half-standing, to lessen the jar, I held the pail in one hand and held myself in the other, not daring to let go even to look at my watch. “But I was afraid to look at the watch. I was afraid to see how near to seven o’clock it might be. The sweat was dropping from my nose, so close was I running to the limit of my time. “Suddenly there was a lurch, and I dove forward, ramming my head into the front of the cab, coming up with a rebound that landed me across the small of my back on the seat, and sent half of my pail of eggs helter-skelter over the floor. “We had stopped. Here was Agassiz’s house; and not taking time to pick up the scattered eggs, I tumbled out, and pounded at the door. “No one was astir in the house. But I would stir them. And I did. Right in the midst of the racket the door opened. It was the maid. “‘Agassiz,’ I gasped, ‘I want Professor Agassiz, quick!’ And I pushed by her into the hall. “‘Go ’way, sir. I’ll call the police. Professor Agassiz is in bed. Go ’way, sir.’ “‘Call him--Agassiz--instantly, or I’ll call him myself!’
