Dr. Andrew Leith Adams, a distinguished English surgeon and naturalist, who resided for a period of several years in Malta, found fossil bones and teeth of hippopotami in various parts of the group. He says in a published account that he "unearthed hundreds of elephant's teeth, together with those of other tropical animals." He also discovered, in caves on the south side of the larger island, vestiges of aquatic birds of a species now extinct, and which in life must have been larger than the swan of our day. The presence of such remains indicates a great change of climatic conditions between the far past and the present time. It is difficult to imagine that Malta was ever the native land of elephants and sea-horses, but Dr. Adams shows, at least to his own satisfaction, that it was once covered with a productive soil and luxuriant vegetation. According to the same authority, it must have had lakes, rivers, and lagoons; trees and shrubs must have flourished in profusion, and it was doubtless part of a land the principal portion of which is now hidden beneath the surging waters of the Mediterranean. Some of the most remarkable of Dr. Adams' discoveries were made in the neighborhood of the village of Melleha, north of St. Paul's Bay, on the principal island of the group. Here, in the sides of the ravine below the hamlet, are numerous caves of various sizes, both natural and artificial. Some of these are thought to be Phoenician tombs, as lamps and lachrymatories have been found in them. A few of these caves are now occupied by Maltese as dwellings. The village of Melleha has a very ancient church, partly excavated in the solid rock, which is held in great veneration, as it is said to have been consecrated by the Apostle Paul. It contains a very ancient picture of the Virgin, believed to have been painted by St. Luke! Penitential pilgrims come from all parts of the group to kneel and pray in this church, a service which, according to the local priests, carries with it absolution for any amount of sin and wickedness. It is needless to say that a good round fee is also contingent thereon.
