The very unpleafant weather that attended us foon after our laft departure hence, led me to enquire of Sen Fidalgo, how the winter had paffed at Nootka. From whom I underfood, that their fituation here had been very irkfome, having been almost conflantly confined to the houfe by inceffant rain; that on the 17th of February a very fevere fhock of an earthquake had been felt, and on the 1ft of April a moft violent ftrom from the fouth-eaft.
