=Climate of Porto Rico.= Its mountainous character gives it a marked diversity of climate, torrential rains falling on the windward side of its mountains, while the leeward sides are comparatively dry. The highest temperature in San Juan since 1876 is 101° and the lowest 57°. In this city a cool breeze, known as the “briza”, adds to the comfort of the late afternoon and evening. The wet season begins a month earlier than in Cuba and lasts a month longer. San Juan is probably the most healthful city in the West Indies, but those reared in northern climates invariably suffer from its enervating influence after several years of continuous residence. Water is abundant, there being some seventy rivers and over a thousand small streams. The mountains are clothed in vegetation to their tops, and frost of a killing nature is practically unknown in the island. =Climate of the Hawaiian Islands.= Much has been written about the charm of the Hawaiian Islands, their mountains, volcanoes, tropical verdure, and delightful climate. It is indeed a garden spot, and its soil and climate make it so. Nowhere in the islands does the temperature reach 90° at any time of the year, while at Honolulu, the largest city and the capital, a temperature lower than 60° is rarely experienced. Of course, as one ascends the high mountains for which the group is noted, much lower temperatures are encountered, while snow is not infrequent near the tops. July and August are the warmest months and January the coldest. The climate is soothing and dreamy and doubtless would prolong the life of many who are aged and slowly passing to their end, and that of others of low vitality but no organic disease. Most of the rain falls November to May, but some falls in every month of the year. At Honolulu the amount is about that which falls in Wisconsin, but at a station in the Kohala Mountains one hundred and fifty-four inches have been measured as the rainfall for seven months, and forty-two inches for one month, the latter being a larger amount than the annual rainfall for the State of Iowa.
