“Would I get him some turtle eggs? he called. Yes, I would. And would I get them to Cambridge within three hours from the time they were laid? Yes, I would. And I did. And it was worth the doing. But I did it only once.

“When I promised Agassiz those eggs, I knew where I was going to get them. I had got turtle eggs there before—at a particular patch of sandy shore along a pond, a few miles distant from the academy.

“Three hours was the limit. From the railroad station to Boston was thirty-five miles; from the pond to the station was perhaps three or four miles; from Boston to Cambridge we called about three miles. Forty miles in round numbers! We figured it all out before he returned, and got the trip down to two hours,—record time:—driving from the pond to the station; from the station by express train to Boston; from Boston by cab to Cambridge. This left an easy hour for accidents and delays.

“Cab and car and carriage we reckoned into our time-table; but what we didn’t figure on was the turtle.” And he paused abruptly.

“Young man,” he went on, his shaggy brows and spectacles hardly hiding the twinkle in the eyes that were bent severely upon me, “young man, when you go after turtle eggs, take into account the turtle. No! No! that’s bad advice. Youth never reckons on the turtle—and youth seldom ought to. Only old age does that; and old age would never have got those turtle eggs to Agassiz.

“It was in the early spring that Agassiz came to the academy, long before there was any likelihood of the turtles’ laying. But I was eager for the quest, and so fearful of failure that I started out to watch at the pond, fully two weeks ahead of the time that the turtles might be expected to lay. I remember the date clearly: it was May 14th.

“A little before dawn—along near three o’clock—I would drive over to the pond, hitch my horse near by, settle myself quietly among some thick cedars close to the sandy shore, and there I would wait, my kettle of sand ready, my eye covering the whole sleeping pond. Here among the cedars I would eat my breakfast, and then get back in good season to open the academy for the morning session.

“And so the watch began.

“I soon came to know individually the dozen or more turtles that kept to my side of the pond. Shortly after the cold mist would lift and melt away, they would stick up their heads through the quiet water; and as the sun slanted down over the ragged rim of tree-tops, the slow things would float into the warm lighted spots, or crawl out and doze comfortably on the hummocks and snags.

“What fragrant mornings those were! How fresh and new and unbreathed! The pond odors, the woods odors, the odors of the ploughed fields—of water-lily, and wild grape, and the dew-laid soil! I can taste them yet, and hear them yet—the still, large sounds of the waking day—the pickerel breaking the quiet with his swirl; the kingfisher dropping anchor; the stir of feet and wings among the trees. And then the thought of the great book being held up for me! Those were rare mornings!
