Fertilization of Lava.--This phenomenon has been thus explained by Sir William Gell, in his 'Topography of Rome and its Vicinity:'--"It has been proved that volcanic lapilli and volcanic productions in general possess in an eminent degree the power of retaining moisture (imbibing with ease seven-eighths of water), and that their humidity is a principal cause of their fertility. Mixed with the soil, and impregnated with a store of moisture acquired during the winter months, they occasion in the ensuing summer the fertility so remarkable in the vicinity of Naples."--vol. i., p. 250.
