It was astonishing how much they all found to do at Cosey Corner; and Mac, instead of lying in a hammock and being read to, as he had expected, was busiest of all. He was invited to survey and lay out Skeeterville, a town which the children were getting up in a huckleberry pasture; and he found much amusement in planning little roads, staking off house-lots, attending to the water-works, and consulting with the "selectmen" about the best sites for public buildings; for Mac was a boy still, in spite of his fifteen years and his love of books. Then he went fishing with a certain jovial gentleman from the West; and though they seldom caught any thing but colds, they had great fun and exercise chasing the phantom trout they were bound to have. Mac also developed a geological mania, and went tapping about at rocks and stones, discoursing wisely of "strata, periods, and fossil remains;" while Rose picked up leaves and lichens, and gave him lessons in botany, in return for his lectures on geology. They led a very merry life; for the Atkinson girls kept up a sort of perpetual picnic; and did it so capitally, that one was never tired of it. So their visitors throve finely, and long before the month was out it was evident that Dr. Alec had prescribed the right medicine for his patients. CHAPTER XIV. _A HAPPY BIRTHDAY._ THE twelfth of October was Rose's birthday, but no one seemed to remember that interesting fact, and she felt delicate about mentioning it, so fell asleep the night before wondering if she would have any presents. That question was settled early the next morning, for she was awakened by a soft tap on her face, and opening her eyes she beheld a little black and white figure sitting on her pillow, staring at her with a pair of round eyes very like blueberries, while one downy paw patted her nose to attract her notice. It was Kitty Comet, the prettiest of all the pussies, and Comet evidently had a mission to perform, for a pink bow adorned her neck, and a bit of paper was pinned to it bearing the words, "For Miss Rose, from Frank." That pleased her extremely, and that was only the beginning of the fun, for surprises and presents kept popping out in the most delightful manner all through the day, the Atkinson girls being famous jokers and Rose a favorite. But the best gift of all came on the way to Mount Windy-top, where it was decided to picnic in honor of the great occasion. Three jolly loads set off soon after breakfast, for everybody went, and everybody seemed bound to have an extra good time, especially Mother Atkinson, who wore a hat as broad-brimmed as an umbrella, and took the dinner-horn to keep her flock from straying away.
