"The destruction of St. Pierre was due to the new crater. The explosion had great superficial force, acting in radial directions, as is evidenced by the dismounting and carrying for yards the guns in the battery on the hill south of St. Pierre and the statue of the Virgin in the same locality, and also by the condition of the ruined houses in St. Pierre. According to the testimony of some persons there was an accompanying flame. Others think the incandescent cinders and the force of their ejection were sufficient to cause the destruction. This must be investigated. I am now following the nature of this." Professor Hill started on Monday, May 26, to visit the vicinity of Mount Pelee, and returned to Fort de France Wednesday morning, nearly exhausted. Professor Hill was near the ruins of St. Pierre on Monday night during the series of explosions from Mount Pelee, and was able to describe the volcanic eruption from close observation. Speaking personally of his expedition he said: "My attempt to examine the crater of Mount Pelee has been futile. I succeeded, however, in getting close to Morne Rouge. At seven o'clock on Monday night I witnessed, from a point near the ruins of St. Pierre, a frightful explosion from Mount Pelee and noted the accompanying phenomena. While these eruptions continue, no sane man should attempt to ascend to the crater of the volcano. Following the salvos of detonations from the mountain, gigantic mushroom-shaped columns of smoke and cinders ascended into the clear, starlit sky, and then spread in a vast black sheet to the south and directly over my head. Through this sheet, which extended a distance of ten miles from the crater, vivid and awful lightning-like bolts flashed with alarming frequency. They followed distinct paths of ignition, but were different from lightning in that the bolts were horizontal and not perpendicular. This is indisputable evidence of the explosive oxidation of the gases after they left the crater. This is a most important observation and explains in part the awful catastrophe. This phenomenon is entirely new in volcanic history. "I took many photographs, but do not hesitate to acknowledge that I was terrified. But I was not the only person so frightened. Two newspaper correspondents, who were close to Morne Rouge some hours before me, became scared, ran three miles down the mountain, and hastened into Fort de France. The people on the north end of the island are terrified and are fleeing with their cattle and effects. I spent Tuesday night in a house at Deux Choux with a crowd of 200 frightened refugees. "Nearly all the phenomena of these volcanic outbreaks are new to science, and many of them have not yet been explained. The volcano is still intensely active, and I cannot make any predictions as to what it will do." CHAPTER XXIV. TERRIBLE VOLCANIC DISASTERS OF THE PAST. BY TRUMBULL WHITE.
