Mindanao, especially the basin of the Agusan, has a vast number of lakes, among them the famous lakes Lanao, Mainit, and Lagusan. Laguna de Bay, near Manila, Lake Naujan in Mindoro, Taal, and Bombon lakes in Batangas, and Lake Bito in Leyte are also noted for size and beauty. [Falls] The Falls of Pagsanjan and the Botocan at Majayjay, in Laguna Province; the Maria Cristina, the Pigduktan, and Kalilokan, in Mindanao, are the largest and most beautiful. [Mineral Springs] Some 170 or more medico-mineral springs, hot and cold, are known in the Islands, many rivaling the most famous of Europe and America. Near Manila are those of Los Baños, Sibul, Lemery, Tivi, and Marilao. [Climate] Father Algué, the world famous Director of the Weather Bureau, divides the climate into three types, the classification being based on distance above sea level and exposure to ocean breezes. November, December, January, and February are the temperate months. The mean average temperature at this season is about 77° to 79° Fahrenheit. In April, May, and June, the hot months, the mean average is between 83° and 84°. In other months it is about 80°. The nights are seldom unpleasantly hot even in the hot season, and a temperature of 100° is a rarity in Manila. The mountain regions of the north are cool as September in the temperate zone. The mean average maximum for Baguio is 80° and the minimum 53°. Far south, nearer the equator, in some localities it is hotter; but Zamboanga and the Provinces of Bukidnon and Lanao boast a most agreeable and healthful climate. The climate is thus mildly tropical. Sunstrokes are unknown. The recorded death rate per 1,000 whites in Manila for 1917 was 8.8, as compared with 16.5 for New York, 15 for San Francisco, 14 for Chicago, 18 for Glasgow, and 22 for Belfast.
