The disappearance of this river takes place within a hundred yards of the railroad station, in the town of San Antonio de los Banos, and furnishes rather an interesting sight for the tourist who is not familiar with this peculiar phenomenon. Although the City of Havana is considered one of the most delightful winter resorts in the Western Hemisphere, there are many who claim, and with reason perhaps, that the Capital has many advantages also as a place in which to spend the summer. Many visitors from the Gulf States in summer have been loath to leave Cuba. The mean annual temperature of Havana varies only twelve degrees throughout the year. During the winter the mercury plays between the two extremes of 58 and 78 degrees, with an average of about 70. During the summer the temperature varies from 75 to 88 degrees, although there are occasional records where the mercury has reached 92 degrees. Even at this temperature, however, no great inconvenience is experienced, since the cool, strong, northeast winds, that blow from the Atlantic, straight across the Island, sweep into the Caribbean the overheated atmosphere that otherwise would hang over the land as it does in the interior of large continents, even in latitudes as high as northern Canada. This continual strong current of air, that blows from the Atlantic during at least 300 days in the year, with its healthful, bracing influence, tempers the heat of the sun that in latitude 22 is directly overhead, and probably prevents sun strokes and heat prostrations, which are absolutely unknown in Havana at any time of the year. During the first Government of Intervention, American soldiers in the months of July and August, 1900, put shingled roofs on barracks and quarters built at Camp Columbia, in the suburbs of Havana, without the slightest discomfort. Officers who questioned the men with more or less anxiety, since they were not accustomed to the tropics, were laughed at for their fears, the soldiers declaring that, “although the sun was a little hot, the breeze was fine, and they didn’t feel any heat.” Of the thousands of horses and mules brought from Kentucky and Missouri not one has ever fallen, or suffered from heat prostration in the Island of Cuba. The nights are invariably cool, so much so that even in July and August, during the early morning hours, a light covering is not uncomfortable. There is every reason to believe that in the near future summer resorts will be successfully established on many of the elevated plateaus and mountainous parks in various sections of the Island.
