On April 21st--accompanied by Mr. Gray, the pastor of the Presbyterian Church, who kindly acted as our guide--after driving through Naples, Portici, and Resina, we slowly ascended the slopes of Mount Vesuvius, which is about 30 miles in circumference at its base; and, whilst going up the steep incline, marked a gradual decrease of vegetation, until great lava fields, consisting of immense black boulders, and enormous quantities of lava, cooled, and hardened into the most fantastic shapes, were reached. At 2 o'clock we alighted at the Hermitage, and afterwards walked towards the eruptive cone, but made no attempt to reach its top. The distant view, however, was very beautiful, and the surroundings on every side were grand. A Museum at the Observatory contains a valuable collection of minerals from Vesuvius, some volcanic bombs, and a few curious scientific instruments, amongst which is an "eisograph" for measuring the duration and violence of earthquakes, so constructed that the precise time of their duration can be measured with the greatest accuracy. Before leaving the Museum, we heard that a gentleman, whilst in the act of mounting the cone of Vesuvius, had just died suddenly of apoplexy, brought on by over exertion during its ascent; and a short time afterwards several men passed us carrying his corpse down the mountain in a chair. He appeared to be about 45 years of age, and was sitting upright, with his head hanging over the left shoulder. His countenance was deadly pale, and life was quite extinct. The sight was both solemn and affecting. On the evening of April 24th, my husband gave a farewell address in English at the Presbyterian Church, when at the close of the service, Mr. Gray, on his own behalf and that of the congregation, publicly expressed his gratitude for "Mr. Müller's valued ministry" amongst them. Our visit to Naples was a very happy one, and the meetings were of a most important character. The next morning we rose at 4, to leave by an early train for Rome, but our stay there was a short one only. That evening Mr. Müller preached at Mr. Wall's Chapel to a large congregation, and the following evening held a meeting at the American Episcopal Church. On Sunday morning, April 27th, he gave an address at the Brethren's Hall, and preached at the Sala Cristiana in the evening from Heb. xi. 24, 25, 26--a solemn farewell sermon. On the 28th we went again to Florence, and when he had held six meetings in that city (including a service at Dr. Comandi's Institution, where, on May 2nd, he addressed the children of the various evangelical schools in Florence), on the morning of the 5th we left, and, after crossing the Appenines, reached Bologna in the afternoon. There he preached in French, with Italian translation, that evening and the next, at Monsieur Roland's Church to crowded congregations.
