Trinidad's Asphalt.
The principal deposit of asphalt in the island of Trinidad is at Lea Brea, where there is an apparently inexhaustible supply. The pitch lake is 110 acres in extent, of unknown depth, and situated 130 ft above the) level of the sea. The removal of 1,720,000 tons during the past 34 years has apparently made no impression on the lake. The lake contains no liquid asphalt, but in other parts of the island the kind from which illuminating and lubricating oils can be distilled is found widely distributed. Glance pitch, also found in the island, is used for electric insulations and for black varnishes.
