“I think I should have fainted had not the turtle just then begun crawling off. I was weak and dizzy; but there, there in the sand, were the eggs! and Agassiz! and the great book! And I cleared the fence, and the forty miles that lay between me and Cambridge, at a single jump. He should have them, trains or no. Those eggs should go to Agassiz by seven o’clock, if I had to gallop every mile of the way. Forty miles! Any horse could cover it in three hours, if he had to; and upsetting the astonished turtle, I scooped out her round white eggs. “On a bed of sand in the bottom of the pail I laid them, with what care my trembling fingers allowed; filled in between them with more sand; so with another layer to the rim; and covering all smoothly with more sand, I ran back for my horse. “That horse knew, as well as I, that the turtles had laid, and that he was to get those eggs to Agassiz. He turned out of that field into the road on two wheels, a thing he had not done for twenty years, doubling me up before the dashboard, the pail of eggs miraculously lodged between my knees. “I let him out. If only he could keep this pace all the way to Cambridge! or even halfway there; and I would have time to finish the trip on foot. I shouted him on, holding to the dasher with one hand, the pail of eggs with the other, not daring to get off my knees, though the bang on them, as we pounded down the wood-road, was terrific. But nothing must happen to the eggs; they must not be jarred, or even turned over in the sand before they came to Agassiz. “In order to get out on the pike it was necessary to drive back away from Boston toward the town. We had nearly covered the distance, and were rounding a turn from the woods into the open fields, when, ahead of me, at the station it seemed, I heard the quick sharp whistle of a locomotive. “What did it mean? Then followed the _puff, puff, puff_, of a starting train. But what train? Which way going? And jumping to my feet for a longer view, I pulled into a side road, that paralleled the track, and headed hard for the station. “We reeled along. The station was still out of sight, but from behind the bushes that shut it from view, rose the smoke of a moving engine. It was perhaps a mile away, but we were approaching, head on, and topping a little hill I swept down upon a freight train, the black smoke pouring from the stack, as the mighty creature got itself together for its swift run down the rails. “My horse was on the gallop, going with the track, and straight toward the coming train. The sight of it almost maddened me--the bare thought of it, on the road to Boston! On I went; on it came, a half--a quarter of a mile between us, when suddenly my road shot out along an unfenced field with only a level stretch of sod between me and the engine. “With a pull that lifted the horse from his feet, I swung him into the field and sent him straight as an arrow for the track. That train should carry me and my eggs to Boston!
