There was noise with the second shock, of an hour after the first. They had no accurate information as to the time of either, nor had any of the people in the valley of the Agri or its tributaries, any notice of unusual lights having been seen.

I had now traced the shock in a south and S.E. direction, to nearly the parallel of the head of the Gulf of Policastro, and it seemed more important to push the examination north and N.E. than to devote much more time, to the region I was in.

My return from Tramutola was made by an entirely different track over the great ridge; crossing two small ridges of hills, and the Torrent Cauoli, near its source, we struck into the valley of the Aggia, a branch of the Agri falling in on its right bank, and ascended by it, to the north side of the Piano of Maorno, leaving the lake upon the south of us, and diverging at Paterno, to the N.E. of Monte St. Elia, a mile or two north, for the purpose of examining cursorily Marsico Nuovo.

At Paterno I diverged northwards towards Marsico Nuovo,
