The next expedition was undertaken to please Helen; she wished to examine the beautiful creeks and caves on the north side, which they had seen from a distance when they sailed round the island. They started on foot one delightful day, and walked briskly, for the air, though balmy, was exhilarating. They followed the course of the river till they came to the lake that fed it, and was fed itself by hundreds of little natural gutters down which the hills discharged the rains. This was new to Helen, though not to Hazel. She produced the map, and told the lake slyly that it was incorrect, a little too big. She took some of the water in her hand, sprinkled the lake with it, and called it Hazelmere. They bore a little to the right, and proceeded till they found a creek shaped like a wedge, at whose broad end shone an arch of foliage studded with flowers, and the sparkling blue water peeped behind. This was tempting, but the descent was rather hazardous at first; great square blocks of rock one below another, and these rude steps were coated with mosses of rich hue, but wet and slippery; Hazel began to be alarmed for his companion. However, after one or two difficulties, the fissure opened wider to the sun, and they descended from the slimy rocks into a sloping hot-bed of exotic flowers, and those huge succulent leaves that are the glory of the tropics. The ground was carpeted a yard deep with their luxuriance, and others, more aspiring, climbed the warm sides of the diverging cliffs, just as creepers go up a wall, lining every crevice as they rose. In this blessed spot, warmed, but not scorched, by the tropical sun, and fed with trickling waters, was seen what marvels "boon Nature" can do. Here our vegetable dwarfs were giants and our flowers were trees. One lovely giantess of the jasmine tribe, but with flowers shaped like a marigold, and scented like a tube-rose, had a stem as thick as a poplar, and carried its thousand buds and amber-colored flowers up eighty feet of broken rock, and planted on every ledge suckers, that flowered again and filled the air with perfume. Another tree about half as high was covered with a cascade of snow-white tulips, each as big as a small flower-pot, and scented like honeysuckle. An aloe, ten feet high, blossomed in a corner, unheeded among loftier beauties. And at the very mouth of the fissure a huge banana leaned across, and flung out its vast leaves, that seemed translucent gold against the sun; under it shone a monstrous cactus in all her pink and crimson glory, and through the maze of color streamed the deep blue of the peaceful ocean, laughing, and catching sunbeams. Helen leaned against the cliff and quivered with delight, and that deep sense of flowers that belongs to your true woman. Hazel feared she was ill. "Ill?" said she. "Who could be ill here? It is heaven upon earth. Oh, you dears! Oh, you loves! And they all seemed growing on the sea, and floating in the sun."
