For many years a considerable tonnage was exported from this bay; the asphalt was crudely mined by dropping steel bars from shallow boats, and the pieces of asphalt broken up in this manner were brought to the surface after a diver had tied a rope around them.

Naturally the production was not steady, and in spite of the high grade of the product which compared favorably with the Trinidad asphalt, the buyers were forced to recur to more ably managed mines for their asphalt. There are many more asphalt deposits of great interest in this Province, notably one on which liquid asphalt running constantly from a gap in a ravine has formed a regular asphalt lake which the neighbors have fenced in to keep the cattle from getting stuck in it. The day will come when a careful geological survey of the Island will be made which will reveal the real extent, importance and relations of all these deposits, solving many vexing problems, and offering new openings to prospectors, geologists and Head-Frame of the "Panchita and Casualidad" Copper prospects, near Cienfuegos. PROVINCE OF SANTA CLARA With the exception of the mountain range on the south coast of the province which ex- tends from near Cienfuegos to the east of Trinidad, and a few lower ranges in the central and eastern part of it, around Sancti Spiritus, the Province of Santa Clara is flat, rolling, and more hilly than mountainous. Gas, oil, asphalt, and a type of cannel coal are commonly found in different localities. Near Itabo, at a place known as San Juan de Motembo, in the northwestern part of the Province, there is a remarkable flow of gas which, since 1800, has been the source of the greatest interest, and has been experimented with by different concerns for different purposes. The gas is believed t
