 Ls another thermal spring of interest. Its waters have a 

 temperature of 92 F., and are saline and purgative. 



The drainage of the Blue Mountain districts is frequent 

 and constant in occurrence and copious in run-off, while 

 in the region of the limestone plateau it is superficially 

 somewhat deficient, often disappearing into underground 

 caverns or breaking out of them in a remarkable manner. 

 As a whole, the island presents two major types of 

 streams one, simple rivers flowing to either coast; and 

 the other, the rivers of the interior basins, which have no 

 outlet to the sea. 



The streams of the first class in the mountain region 

 are marked by deep V-shaped canons in their upper 

 courses, and great deposits of ancient alluvium in their 

 lower parts. The run-off of these is constant, but variable 

 in quantity, owing to torrents. The streams found in the 

 basins of the plateau region rise from springs, flow for 

 short distances, then disappear into the ground without 

 visible outlet to the sea. Of this type of rivers are the 

 Minho; Rio Hoe, near Moneague; Great River, in the 

 southeast corner of St. Ann; Pedro River, which sinks 

 at the corner of St. Ann, Clarendon, and St. Catherine 

 parishes; and Yankee and Cave rivers, which unite and 

 disappear into a sink on the borders of St. Ann and 

 Clarendon. The latter stream is ten miles long. Hector 

 River, forming the boundary of Manchester and Tre- 

 lawney, sinks at the northeast corner of St. Elizabeth; 

 Hicks River, in Trelawney ; Pine and Dry rivers, in the 

 northern part of St. Elizabeth; Niagara, Chester, and 

 Tangle rivers, in the southern part of St. James. 



Jamaica also possesses many interesting caverns. The 

 Cave of Mexico in St. Elizabeth, through which Black 

 River flows, is probably the largest. Cave Hall Pen, near 

 Dry Harbor, is of great length and has two branches ; the 

 various rooms are designated grottoes, halls, domes, and 

 galleries, and are lined with beautiful stalactites and
