At Pugliano the party left the train, and after a long and tiresome wait at the station changed to the light electric railway that was to take them up Vesuvius. The little carriage resembled a tramcar, and its wide glass windows afforded excellent views of the scenery _en route_. Up--up--up they went, gradually getting higher and higher. It was marvelous how the vegetation altered as they ascended. The cactuses, olives, almonds, and peach orchards gave way to hillsides covered with small chestnut, oak, or poplar trees, and the poppies and daisies were succeeded by broom bushes and clumps of rosemary. They were getting on to the region of the lava, and all the ground was brown, like newly turned peat. Men were busy digging terraces in the volcanic earth, to plant vines, working calmly as if the great cone above them had never belched forth fire and ashes. "How _dare_ they live here?" shuddered Peachy, pointing to the tiny dwellings which had been reared here and there. "When they see all the ruin round them, aren't they afraid? What makes them go back?" "The ground is so rich," explained Miss Morley. "Nothing grows vines so splendidly as volcanic earth. The people get fatalistic, and think it worth risking their lives to have these fruitful little farms. They say the mountain may not be angry again for years, and they will take their chance." "It's smoking now," said Lorna. "I suppose it's safe?" asked Delia anxiously. "Perfectly safe to-day or we shouldn't have been allowed to go up in the electric railway. Do you see that big building--the observatory? Careful investigations are made every day of the crater, and the results telegraphed down to Naples. If there were the slightest hint of danger the trains would be stopped and tourists turned back." The journey was ever upwards, over great wastes of rough brown lava, which looked as if some giant, in play, had squeezed out the contents of enormous tubes of oil paint on to the mighty palette of the mountain side. The air had grown fresh and cold, for they were at an altitude approaching 4000 feet, and, but for the scenery, might have imagined themselves in Wales or Scotland.
