The conference at Leeds being concluded, he left that town, on the 12th of May, for Newcastle, where he found some of the Methodists had left the Church already, and others were on the point of doing so, and all, “as they supposed, on his authority!” Three weeks were spent in the Newcastle circuit. He then set out for London, and, at the end of the first day’s journey, reached Osmotherley.[237] Here he made strict inquiry concerning an event of recent occurrence, and which at the time excited great attention. Osmotherley lies nestled nearly at the foot of a long mountain range, known by the name of Black Hambleton. A few weeks before, a part of the mountain consisting of a vast ridge of rock, called Whiston Cliff, was split asunder, amid a sound as of rolling thunder. On March 25, there was a loud noise issuing from the mountain, but nothing more. Next day, a huge piece of the rocky precipice, fifteen yards thick, ten high, and above twenty broad, was torn from the mountain side and thrown into the valley. The ground shook, and immense stones, of several tons weight, rose like giants out of the ground below, and rolled to and fro with marvellous velocity. On the three succeeding days, the ground continued trembling; in many places the earth clave asunder; and huge rocks turned upside down and moved in all directions. Patches of ground, as much as fifty yards in diameter, were lifted bodily, and, burdened with rocks and even trees, were removed to a considerable distance, without the least fissure being created by the transit. In a space of about forty acres, the earth was cleft in a thousand places, while the cliff, from which the rest was torn, was white as snow, and, glittering in the sunlight, was visible at a distance of many miles.
