Our favourite walk was to Keller's Landing, an old tumbledown lumber-wharf on the Tennessee River, used during the Civil War to land soldiers. There we spent many happy hours and played at learning geography. I built dams of pebbles, made islands and lakes, and dug river-beds, all for fun, and never dreamed that I was learning a lesson. I listened with increasing wonder to Miss Sullivan's descriptions of the great round world with its burning mountains, buried cities, moving rivers of ice, and many other things as strange. She made raised maps in clay, so that I could feel the mountain ridges and valleys, and follow with my fingers the devious course of rivers. I liked this, too; but the division of the earth into zones and poles confused and teased my mind. The illustrative strings and the orange stick representing the poles seemed so real that even to this day the mere mention of temperate zone suggests a series of twine circles; and I believe that if any one should set about it he could convince me that white bears actually climb the North Pole.

Arithmetic seems to have been the only study I did not like. From the first I was not interested in the science of numbers. Miss Sullivan tried to teach me to count by stringing beads in groups, and by arranging kindergarten straws I learned to add and subtract. I never had patience to arrange more than five or six groups at a time. When I had accomplished this my conscience was at rest for the day, and I went out quickly to find my playmates.

In this same leisurely manner I studied zoology and botany.

Once a gentleman, whose name I have forgotten, sent me a collection of fossils—tiny mollusk shells beautifully marked, and bits of sandstone with the print of birds' claws, and a lovely fern in bas-relief. These were the keys which unlocked the treasures of the antediluvian world for me. With trembling fingers I listened to Miss Sullivan's descriptions of the terrible beasts, with uncouth, unpronounceable names, which once went tramping through the primeval forests, tearing down the branches of gigantic trees for food, and died in the dismal swamps of an unknown age. For a long time these strange creatures haunted my dreams, and this gloomy period formed a somber background to the joyous Now, filled with sunshine and roses and echoing with the gentle beat of my pony's hoof.

Another time a beautiful shell was given me, and with a child's surprise and delight I learned how a tiny mollusk had built the lustrous coil for his dwelling place, and how on still nights, when there is no breeze stirring the waves, the Nautilus sails on the blue waters of the Indian Ocean in his "ship of pearl." After I had learned a great many interesting things about the life and habits of the children of the sea—how in the midst of dashing waves the little polyps build the beautiful coral isles of the Pacific, and the foraminifera have made the chalkhills of many a land—my teacher read me "The Chambered Nautilus," and showed me that the shell-building process of the mollusks is symbolical of the development of the mind. Just as the wonder-working mantle of the Nautilus changes the material it absorbs from the water and makes it a part of itself, so the bits of knowledge one gathers undergo a similar change and become pearls of thought.
