Sophie’s eyes shone approval, for she understood this love of independence, and had come to America because she longed for new scenes and greater freedom than her native land could give her. Education is a large word, and both girls felt that desire for self-improvement that comes to all energetic natures. Sophie had laid a good foundation, but still desired more; while Tilly was just climbing up the first steep slope which rises to the heights few attain, yet all may strive for. "That is beautiful! You will do it! I am glad to help you if I may. See, I have many books; will you take some of them? Come to my room to-morrow and take what will best please you. We will say nothing of it, and it will make me a truly great pleasure." As Sophie spoke, her little white hand touched the strong, sunburned one that turned to meet and grasp hers with grateful warmth, while Tilly’s face betrayed the hunger that possessed her, for it looked as a starving girl’s would look when offered a generous meal. "I _will_ come. Thank you so much! I don’t know anything, but just blunder along and do the best I can. I got so discouraged I was real desperate, and thought I ’d have one try, and see if I could n’t earn enough to get books to study this winter. Folks buy berries at the cottages; so I just added flowers and shells, and I ’m going to bring my boxes of butterflies, birds’ eggs, and seaweeds. I ’ve got lots of such things; and people seem to like spending money down here. I often wish I had a little of what they throw away." Tilly paused with a sigh, then laughed as an impatient movement caused a silver clink; and slapping her pocket, she added gayly,-- "I won’t blame ’em if they ’ll only throw their money in here." Sophie’s hand went involuntarily toward her own pocket, where lay a plump purse, for papa was generous, and simple Sophie had few wants. But something in the intelligent face opposite made her hesitate to offer as a gift what she felt sure Tilly would refuse, preferring to earn her education if she could. "Come often, then, and let me exchange these stupid bills for the lovely things you bring. We will come this afternoon to see you if we may, and I shall like the butterflies. I try to catch them; but people tell me I am too old to run, so I have not many." Proposed in this way, Tilly fell into the little trap, and presently rowed away with all her might to set her possessions in order, and put her precious earnings in a safe place. The mermaids clung about the boat as long as they dared, making a pretty tableau for the artists on the rocks, then swam to shore, more than ever eager for the picnic on Light-house Island. They went, and had a merry time; while Tilly did the honors and showed them a room full of treasures gathered from earth, air, and water, for she led a lonely life, and found friends among the fishes, made playmates of the birds, and studied rocks and flowers, clouds and waves, when books were wanting.
