The south coast also abounds in bays and harbors, but those which deserve particular attention are the ports of Guánica and Hobos, or Jovos, near Guayama. In Guánica vessels drawing 21 feet of water may enter with perfect safety and anchor close to the shore. Hobos or Jovos is a haven of considerable importance; sailing vessels of the largest class may anchor and ride in safety; it has 4 fathoms of water in the shallowest part of the entrance, but it is difficult to enter from June to November as the sea breaks with violence at the entrance on account of the southerly winds which prevail at this season. All the large islands in the tropics enjoy approximately the same climate. The heat, the rains, the seasons, are, with trifling variations, the same in all, but the number of mountains and running streams, the absence of stagnant waters and general cultivation of the land in Puerto Rico do, probably, powerfully contribute to purify the atmosphere and render it more salubrious to Europeans than it otherwise would be. In the mountains one enjoys the coolness of spring, but the valleys, were it not for the daily breeze which blows from the northeast and east, would be almost uninhabitable for white men during part of the year. The climate of the north and south coasts of this island, though under the same tropical influence, is nevertheless essentially different. On the north coast it sometimes rains almost the whole year, while on the south coast sometimes no rain falls for twelve or fourteen months. On the whole, Puerto Rico is one of the healthiest islands in the West Indies, nor is it infested to the same extent as other islands by poisonous snakes and other noxious reptiles. The laborer may sleep in peace and security in the midst of the forest, by the side of the river, or in the meadow with his cattle with no other fear than that of an occasional centipede or guabuá (large hairy spider). Unlike most tropical islands there are no indigenous quadrupeds and scarcely any of the feathered tribe in the forests. On the rivers there are a few water-fowl and in the forests the green parrot. There are neither monkeys nor rabbits, but rats and mongooses infest the country and sometimes commit dreadful ravages in the sugar-cane. Ants of different species also abound. CHAPTER XXVIII ORIGIN, CHARACTER, AND CUSTOMS OF THE PRIMITIVE INHABITANTS OF BORIQUÉN The origin of the primitive inhabitants of the West Indian Archipelago has been the subject of much learned controversy, ending, like all such discussions, in different theories and more or less verisimilar conjecture.
