"Most likely," returned Allan, dryly; "it is a human failing. What is the case in point, Frankie?" Allan was the only one of us who ever called Dot by his proper name. "I should not mind growing up to be a man," replied Dot, fencing a little, "if I were big and strong like you," taking hold of the huge sinewy hand. "I could work then for mother and the girls; but now you will be always obliged to take care of me, and so--and so--" and here Dot's lips quivered a little, "I would rather go with dear father, if Esther would not cry about it so." "No, no, you must stay with us, Sonny," returned Allan, cheerily. "Esther and I are not going to give you up so easily. Why, look here, Frankie; I will tell you a secret. One of these days I mean to have a nice little house of my own, and Esther and you shall come and live with me, and I will go among my patients all the morning, and in the evening I shall come home very lazy and tired, and Esther shall fetch me my slippers and light the lamp, and I shall get my books, and you will have your drawing, and Esther will mend our clothes, and we shall be as cozy as possible." "Yes, yes," exclaimed Dot, clapping his hands. The snug picture had fascinated his childish fancy; Allan's fireside had obscured the lights of paradise. From this time this imaginary home of Allan's became his favorite castle in the air. When we were together he would often talk of it as though it were reality. We had planted the garden and furnished the parlor a dozen times over before the year was out; and so strong is a settled imagination that I am almost sure Dot believed that somewhere there existed the little white cottage with the porch covered with honeysuckle, and the low bay-window with the great pots of flowering plants, beside which Dot's couch was to stand. I don't think Jack enjoyed these talks so much as Dot and I did, as we made no room for her in our castle-building. "You must not live with us, Jack," Dot would say, very gravely; "you are only a girl, and we don't want girls"--what was I, I wonder?--"but you shall come and see us once a week, and Esther will give you brown bread and honey out of our beehives; for we had arranged there must be a row of beehives under a southern wall where peaches were to grow; and as for white lilies, we were to have dozens of them. Dear, dear, how harmless all these fancies were, and yet they kept us cheerful and warded off many an hour of depression from pain when Dot's back was bad. I remember one more thing that Allan said that night, when we were all better and more cheerful, for it was rather a grave speech for a young man; but then Allan had these fits of gravity.
