Owing to the proximity of the northwestern part of Cuba to our own continent, the climate is somewhat variable, and at a height of five hundred feet above the level of the sea, ice is sometimes, though rarely formed; but, as has already been said in these notes, snow never falls upon the island. At long intervals Cuba has been visited by brief hailstorms, and persons who tell you this will add, "but we never have known it in our day." In the cities and near the swamps, the yellow fever, that scourge of all hot climates, prevails from the middle of June to the last of October; but in the interior of the island, where the visitor is at a wholesome distance from humidity and stagnant water, it is no more unhealthy than our own cities in summer. It is doubtful if Havana, even in the fever season, is any more unhealthy than New Orleans at the same period of the year. Fevers of different degrees of malignity prevail from May to November, and occasionally throughout the year. Among these the yellow fever is the most dangerous, and sooner or later all resident foreigners seem to suffer from it, as a sort of acclimation; once experienced, however, one is seldom attacked a second time. In the ports yellow fever is often induced by carelessness and exposure; excesses on the part of foreign sailors are frequently the cause of its fatal attack upon them. The thermometer is never known to rise so high in Havana or Santiago, the opposite extremes of the island, as it does sometimes in New York and Boston. The average temperature is recorded as being 77°, maximum 89°, minimum 50° Fahrenheit. We have been thus elaborate as regards this matter because it is of such general interest to all invalids who annually seek an equable clime.
The principal cities are Havana, with a population of nearly three hundred thousand; Matanzas, with fifty thousand; Puerto Principe, thirty thousand; Cienfuegos, twenty-five thousand; Trinidad, fourteen thousand; San Salvador, ten thousand; Manzanillo, Cardenas, Nuevitas, Sagua la Grande, and Mariel. Among its largest and finest harbors those of Havana, Santiago de Cuba, Nipe, and Nuevitas are the best; the bay of Matanzas is also large, but shallow. This city stands next to Havana in population, but not in commercial importance. It is said to be healthier than the capital, but it lacks those attractions of life and gayety which are essential even to invalids to render them contented. The streets are wide, and many of the Moorish characteristics of Spanish cities, so common in both this island and the European peninsula, are wanting here. It was built much later and more under foreign direction than Havana. The secret of the superior health of Matanzas over that of the capital is undoubtedly because of its better drainage and general cleanliness.
