The air is sweet with apple bloom, And sweet the laid dust down the lane, The meadow’s marge of calamus, And sweet the robins in the rain. O greening time of bloom and song! O fragrant days of tender pain! The wet, the warm, the sweet young days With robins singing in the rain. CHAPTER XI TURTLE EGGS FOR AGASSIZ I took down, recently, from the shelves of a great public library, the four volumes of Agassiz’s “Contributions to the Natural History of the United States.” I doubt if anybody but the charwoman, with her duster, had touched those volumes for twenty-five years. They are a monumental work, the fruit of vast and heroic labors, with colored plates on stone, showing the turtles of the United States, and their life-history. The work was published more than half a century ago, but it looked old beyond its years--massive, heavy, weathered, as if dug from the rocks; and I soon turned with a sigh from the weary learning of its plates and diagrams to look at the preface. Then, reading down through the catalogue of human names and of thanks for help received, I came to a sentence beginning:-- “In New England I have myself collected largely; but I have also received valuable contributions from the late Rev. Zadoc Thompson of Burlington; ... from Mr. D. Henry Thoreau of Concord; ... and from Mr. J. W. P. Jenks of Middleboro.” And then it hastens on with the thanks in order to get to the turtles, as if turtles were the one and only thing of real importance in all the world. Turtles are important--interesting; so is the late Rev. Zadoc Thompson of Burlington. Indeed any reverend gentleman who would catch turtles for Agassiz must have been interesting. If Agassiz had only put a chapter into his turtle book about him! and as for the Mr. Jenks of Middleboro (at the end of the quotation) I know that he was interesting; for years later, he was an old college professor of mine. He told me some of the particulars of his turtle contributions, particulars which Agassiz should have found a place for in his big book. The preface says merely that this gentleman sent turtles to Cambridge by the thousands--brief and scanty recognition. For that is not the only thing this gentleman did. On one occasion he sent, not turtles, but turtle _eggs_ to Cambridge--_brought_ them, I should say; and all there is to show for it, so far as I could discover, is a small drawing of a bit of one of the eggs! Of course, Agassiz wanted to make that drawing, and had to have a _fresh_ turtle egg to draw it from. He had to have it, and he got it. A great man, when he wants a certain turtle egg, at a certain time, always gets it, for he gets some one else to get it for him. I am glad he got it. But what makes me sad and impatient is that he did not think it worth while to tell us about the getting of it.
