WISCONSIN.- The mean annual precipitation is 31.5 inches and is uniformly distributed over the State; at Milwaukee it is 31 inches.

WYoMING.- It averages 13 inches, ranging from 8 Inches in some' places to '20 inches in the Yellowstone Park.

Along the Appalachian altitudes from New York to the Gulf of Mexico there is a greater precipitation than there is at lower levels along the Atlantic Coast. From the United States Weather Bureau reports of the mean annual precipitation, measured at several stations in each New England State over a period of years, it appears that it averaged in Maine 44.6 inches, in New Hampshire 40.6 inches, in Vermont 382 inches, in Massachusetts 44.6 inches, in Rhode Island 49 inches and in Connecticut 47.2 inches.

Canada.-In Canada it varies in the western, central and eastern provinces as it does in the United States. At Victoria it averaged 37.77 inches, at Port Simpson 94.63 inches, at Regina 9.03 inches, at Prince Albert 14.45 inches, at Winnepeg 19.53 inches, at Port Arthur 23.58 inches, at Toronto 33.94 inches, in Quebec 28.76 to 41.5 inches, in New Brunswick 32.6 inches with 97.5 inches of snow, in Nova Scotia 39.6 inches and 77.5 inches of snow.

Latin America.- In other countries of the western hemisphere records of precipitation are meagre. However, the unofficial reports indicate that the annual precipitation is abundant for the water supply of all the cities whether or not they be located on lakes, rivers and other fresh waters. In Mexico, at Vera Cruz, it meas ured 183 inches as maximum rainfall. In Cen tral America precipitation varies greatly in different sections. Rainfall in the latter ranges from 50 to 200 inches annually. In Cuba at Havana it ranges from 40 to 80 inches. There is a great variation of precipitation in South America owing to its physical formation with the lofty Andes extending along its entire west ern border and their many lateral ranges, its high arid plateaus and swampy regions, its vast area extending from 12° north latitude across the equator to 55° south latitude and from 35° to 82' west longitude, its tropical heat over most of it and its wintry climate in some other localities and its general location with reference to the Caribbean Sea, the Atlantic and Pacific oceans. The climate is as variable as all such

physical conditions can produce. Generally spealdng, the precipitation is not only abundant for its water supply in most of its coastal re gions, but over some areas it is excessive. Over its interior elevated districts it is slight and great desert regions exist in Brazil, Bolivia, Peru, Argentina and Patagonia, where there is but little precipitation. The annual precipitation at Bogota is 44 inches, along the coast 73 inches, at Caracas from 24 to 34 inches, at Val divia 108 to 115 inches, in Uruguay 43 inches, in Argentina from 2 to 63 inches and in Pata gonia from 19 to 97 inches. In many parts of i Brazil there is heavy rainfall and in other mountain sections there are heavy snowstorms. At Rio de Janeiro it is from 43 to 59 inches, at Blumenau 53 inches and at Ceara 60 inches. The precipitation is abundant in most of the Western States, where high mountains intercept the vapor-laden winds from the Pacific. There are many large lakes high above sea-level, one of them being Lake Titicaca, with an area of 5,000 square miles, 12,545 feet above the sea. It falls in rain and snow and not only waters vast arms but supplies the headwaters of the Amazon and other great rivers.

Europe.- In Europe a few measurements will illustrate the mean annual precipitation. In England the annual precipitation vanes from 25 inches or less at the mouth of the Thames to 60 inches in the lake district and in a part of Wales, while in other districts it is 40 inches. In the western counties of England near high hills it ranges from 80 to 150 inches, while in other sections it averages from 30 to 45 inches. In the eastern counties it ranges from 20 to 28 inches. The mean annual rainfall on the Vyrnwy watershed is 65.16 inches. At Litton in Bristol watershed for 58 years it averaged 41.1 inches and at Bristol 30.9 inches. Over the Thames area for 21 years it averaged 26.9 inches. Over Derwent Valley it varies from 35 inches in the south to 61 inches in the north. Over the Sheffield waterworks catchment areas precipitation averaged about 47 inches. The average rainfall over the whole of England is about 30 inches.
