Their hotel was perched directly over the sea. From the balcony of their sitting-room they looked down a sheer cliff some sixty feet high, into the water; their bedrooms opened on a garden of roses, with an orange grove beyond. Not far from them was the great gorge which cuts the little town of Sorrento almost in two, and whose seaward end makes the harbor of the place. Katy was never tired of peering down into this strange and beautiful cleft, whose sides, two hundred feet in depth, are hung with vines and trailing growths of all sorts, and seem all a-tremble with the fairy fronds of maiden-hair ferns growing out of every chink and crevice. She and Amy took walks along the coast toward Massa, to look off at the lovely island shapes in the bay, and admire the great clumps of cactus and Spanish bayonet which grew by the roadside; and they always came back loaded with orange-flowers, which could be picked as freely as apple-blossoms from New England orchards in the spring. The oranges themselves at that time of the year were very sour, but they answered as well for a romantic date, "From an orange grove," as if they had been the sweetest in the world. They made two different excursions to Pompeii, which is within easy distance of Sorrento. They scrambled on donkeys over the hills, and had glimpses of the far-away Calabrian shore, of the natural arch, and the temples of Paestum shining in the sun many miles distant. On Katy's birthday, which fell toward the end of January, Mrs. Ashe let her have her choice of a treat; and she elected to go to the Island of Capri, which none of them had seen. It turned out a perfect day, with sea and wind exactly right for the sail, and to allow of getting into the famous "Blue Grotto," which can only be entered under particular conditions of tide and weather. And they climbed the great cliff-rise at the island's end, and saw the ruins of the villa built by the wicked emperor Tiberius, and the awful place known as his "Leap," down which, it is said, he made his victims throw themselves; and they lunched at a hotel which bore his name, and just at sunset pushed off again for the row home over the charmed sea. This return voyage was almost the pleasantest thing of all the day. The water was smooth, the moon at its full. It was larger and more brilliant than American moons are, and seemed to possess an actual warmth and color. The boatmen timed their oar-strokes to the cadence of Neapolitan _barcaroles_ and folk-songs, full of rhythmic movement, which seemed caught from the pulsing tides. And when at last the bow grated on the sands of the Sorrento landing-place, Katy drew a long, regretful breath, and declared that this was her best birthday-gift of all, better than Amy's flowers, or the pretty tortoise-shell locket that Mrs. Ashe had given her, better even than the letter from home, which, timed by happy accident, had arrived by the morning's post to make a bright opening for the day.
