The fact that the main axis of the island, with its seven hundred mile stretch of territory, extends from southeast to northwest, almost at right angles to the general direction of the wind, plays a very important part in the equability of Cuba's climate. Then again, the island is completely surrounded by oceans, the temperature of which remains constant, and this plays an important part in preventing extremes of heat or cold. Ice, of course, cannot form, and frost is found only on the tops of the tallest mountain ranges. The few cold days during winter, when the thermometer may drop to 60 after sundown, are the advance waves of "Northers" that sweep down from the Dakotas, across Oklahoma and the great plains of Texas, eventually reaching Cuba, but only after the sting of the cold has been tempered in its passage of six hundred miles across the Gulf of Mexico. A temperature of 60 degrees in Cuba is not agreeable to the natives, or even to those residents who once lived in northern climes. This may be due to the fact that life in the tropics has a tendency to thin the blood, and to render it less resistant to low temperature; and also because Cuban residences are largely of stone, brick or reinforced concrete, with either tile or marble floors, and have no provision whatever against cold. And, although the walls are heavy, the windows, doors and openings are many times larger than those of residences in the United States, hence the cold cannot readily be excluded as in other countries. There is said to be but one fireplace on the Island of Cuba, and that was built in the beautiful home of an American, near Guayabal, just to remind him, he said, of the country whence he came. Again, in the matter of rainfall and its bearing on the climate of a country, Cuba is very fortunate. The rains all come in the form of showers during the summer months, from the middle of May until the end of October, and serve to purify and temper the heat of summer. On the other hand, the cooler months of winter are quite dry, and absolutely free from the chilling rains, sleets, snows, mists and dampness, that endanger the health, if not the life, of those less fortunate people who dwell in latitudes close to 40 degrees. Cloudy, gloomy days are almost unknown in Cuba, and the sun can be depended upon to shine for at least thirty days every month, and according to the testimony of physicians nothing is better than sunshine to eliminate the germs of contagious diseases. Hence we can truthfully say that in the matter of climate and health, Cuba asks no favor of any country on earth. CHAPTER V
