=A Thirteenth-Century Miracle.=--The legend of St. Prokopy relates that on the 25th of June, 1290, the city of Wilikij Ustjug, government of Vologda, southern Russia, was imminently threatened by a violent storm. The populace appealed to the saint, and, by virtue of his prayers, the storm changed its direction, and, passing on one side of the city, spent its fury upon a desert spot about fifteen miles away, where it left, with hail, a mass of fire-marked stones, the fall of which wrought great havoc with the undergrowth. The incident made a deep impression upon the minds of the people, so that the story is still current and alive after the lapse of six hundred years. A testimony to what the people believe is its truth may be found by visiting the spot, where a surface extending along about four miles is covered with blocks of stone, assumed to be meteorites. A church dedicated to St. Prokopy has been built in the neighboring village of Loboff or Catoval, and near it stands a curious little wooden chapel of great antiquity, the foundation of which was made of the stones that fell. The church is decorated with pictures of St. Prokopy and of incidents of the meteoric storm, and one of the stones that fell has been mounted on a pedestal in the cathedral of Ustjug, where it is an object of devotion. Mr. Melnikoff, Conservator of the Mineralogical Collections of the Mining Institute of St. Petersburg, has examined the place and the stones, and finds that they are not meteoric and heavenly at all, but simply earthly granite and sandstone. Yet M. Stanislas Meunier suggests, in _La Nature_, that the story, so carefully treasured up for six hundred years, may have a foundation. That such stones as lie on the ground at Catoval may have been taken up and transplanted by a tornado of extreme violence he regards as within the possibilities. M. Meunier has himself investigated a phenomenon of the kind in France, where the ground was “mitrailled” with stones measuring one, two, and three cubic centimetres, which had been brought a distance of one hundred and fifty kilometres. Another possible explanation is that the stones were already there, so concealed by the dense growth as not to attract particular attention, but became more plainly obvious when the ground had been cleared by the tornado.
