_Yalos._ Frosts (whence, perhaps corruptly, Yallahs), the high white cliffs having the appearance of a frosty covering. [Now called Yallahs. Long was probably wrong in connecting Yallahs with Yalos. The Hatô de Ayala extended from Bull Bay nearly to Morant Bay, and the name is probably a personal one. Pedro Lopez de Ayala was a celebrated poet and politician in the fourteenth century; Pedro de Ayala was Spanish envoy to the Court of St. James in 1498; and, curiously, a recent Spanish representative at Havana bore the name de Ayala. There was a Captain Yhallahs, a privateer who flourished in Jamaica in and about 1671, and the locality may have been named after him.] _Luidas._ Perhaps from Luzida; gay, fine. [Lluidas Vale is in St. Catherine.] _Martha Brea._ Martha, a woman’s name; Brea, tar; perhaps a nickname of some Spanish sailor’s Dulcinea like the English vulgar appellation _Jack Tar_. [Martha Brea village and river are in Trelawny. The name is a corruption of Rio Matibereon.] No traces are to be found to-day of the following: Alta Mela, Rio de Camarones, Caborida, Carvil Bahia, Guada Bocca, Jarisse Punta, Javareen, Multi Bezon Rio, Perexil Insula. Of corruptions of Spanish names the best known are: Agualta (Agua Alta, the deep river); Bog Walk (Boca d’Agua, water’s mouth); and Mount Diablo. Cagua became with the English Caguay, then Cagway when it was renamed Port Royal. Those who see in Porus a survival of the name of Columbus’s companion, Porras, are probably drawing on a fertile imagination. Columbus and his companions saw little of the interior of the island. It is more probably called after some well sunk there, or from the porous nature of the soil, “pitted with holes.” In the English edition of Ferdinand Columbus’s “Historie,” we read that the Morant Cays were called by Columbus _Los Poros_ because “not finding water in them they dug pits in the sand”; but in the Italian edition (Venice, 1571) they are called “le pozzi” (the pits), and in the Spanish edition of 1749 they are called “Las Poças” (the pits). It is possible that in the case of Porus, as in that of the Morant Cays, there has been a confusion between _Poros_ and _Pocas_; and that the town in Manchester should be called Poças. The Spaniards called the Black River, el Caovana (the Mahogany River). In the English section of Jamaica history for the two centuries from 1655 to 1855, there is a wide field of exploration.
