I buried two of my children yesterday--at Concord, Mass., and feel so heartbroken this morning that I shall need to adopt two more instantly to supply their place; and lo and behold you and William present yourselves, or if you decline the honour Ellen and Baby. Mary and I trotted forth last Wednesday, bearing Wilky and Bob in our arms to surrender them to the famous Mr. Sanborn. The yellowest sunshine and an atmosphere of balm were all over the goodly land, while the maple, the oak and the dogwood showered such splendours upon the eye as made the Champs Elysees and the Bois appear parvenus and comical. Mrs. Clark is a graceless enough woman outwardly, but so tenderly feathered inwardly, so unaffectedly kind and motherly toward the urchins under her roof, that one was glad to leave them in that provident nest. She has three or four other school-boarders, one of them a daughter of John Brown--tall, erect, long-haired and freckled, as John Brown's daughter has a right to be. I kissed her (inwardly) between the eyes, and inwardly heard the martyred Johannes chuckle over the fat inheritance of love and tenderness he had after all bequeathed to his children in all good men's minds. An arch little Miss Plumley also lives there, with eyes full of laughter and a mouth like a bed of lilies bordered with roses. How it is going to be possible for my two boys to pursue their studies in the midst of that bewilderment I don't clearly see. I am only sure of one thing, which is that if I had had such educational advantages as that in my youth I should probably have been now far more nearly ripe for this world's business. We asked to see Miss Waterman, one of the teachers quartered in the house, in order to say to her how much we should thank her if she would occasionally put out any too lively spark she might see fall on the expectant tinder of my poor boys' bosoms; but Miss W. herself proved of so siliceous a quality on inspection--with round tender eyes, young, fair and womanly--that I saw in her only new danger and no promise of safety. My present conviction is that a general conflagration is inevitable, ending in the total combustion of all that I hold dear on that spot. Yet I can't but felicitate our native land that such magnificent experiments in education go on among us.
