It is the wettest place in the world. In 1861 the rainfall there reached 905 inches. NOTE-The mean annual temperature of the globe is 50° Fahr. The average rainfall is 36 inches, Greatest Altitude in Each State. 'FROM THE RECORDS OF THE UNITED STATES GEOLOGICAL SURVEY. The lowest point of dry land in the United States is in Death Valley, Cal., 278 feet below sea level. NOTE.-The above table was prepared for THE WORLD ALMANAC by the Geographic Branch of the United States Geological Survey. It should be stated in connection with this table that it presents only points whose heights are matters of record, and that in several cases in the high mountain region of the far West and the Pacific Slope it is well known that there are higher points within the State or Territory whose heights are not yet known with accuracy, and consequently cannot be given. This table was revised by the United States Geological Survey to September 1, 1907. *Western end of Beaver County, Oklahoma, reaches 5,000 feet elevation. Weather Flags OF THE WEATHER BUREAU, U. S. DEPARTMENT OF AGRICULTURE. THE Weather Bureau furnishes, when practicable, for the benefit of all interests dependent upon weather conditions, the "Forecasts' which are prepared daily at the Central Office in Washington, D. C., and certain designated stations. These forecasts are telegraphed to stations of the Weather Bureau, railway officials, postmasters, and many others, to be communicated to the public by means of flags or steam whistles. The flags adopted for this purpose are five in number, and of the forms and colors indicated below: No. 1. White Flag. EXPLANATION OF WEATHER FLAGS. No. 2. No. 3. No. 4. No. 5. Blue Flag. White and Blue Flag. Black Triangular Flag. White Flag with black square in centre. Clear or fair weather. Rain or snow. Local rain or snow. Temperature. Cold wave. When number 4 is placed above number 1, 2, or 3, it indicates warmer; when below, colder; when not displayed, the temperature is expected to remain about stationary. During the late Spring and early Fall the cold-wave flag is also used to indicate anticipated frosts. WHISTLE SIGNALS. A warning blast of from fifteen to twenty seconds duration is sounded to attract attention. After this warning the longer blasts (of from four to six seconds duration) refer to weather, and shorter blasts (of from one to three seconds duration) refer to temperature; those for weather are sounded first. By repeating each combination a few times, with intervals of ten seconds, liability to error in reading the signals may be avoided. As far as practicable the forecast messages will be telegraphed at the expense of the Weather Bureau; but if this is impracticable, they will be furnished at the regular commercial rates and sent "collect." In no case will the forecasts be sent to a second address in any place, except at the expense of the applicant. Persons desiring to display the flags or sound the whistle signals for the benefit of the public should communicate with the Weather Bureau officials in charge of the climatological service of their respective States, the central stations of which are as follows: The Ancient and Modern Year. THE Athenians began the year in June, the Macedonians in September, the Romans first In March and afterward in January, the Persians on August 11, the ancient Mexicans on February 23, the Mohammedans in July. The Chinese year, which begins early in February, is similar to the Mohammedan in having 12 months of 29 and 30 days alternately; but in every nineteen years there are seven years which have 13 months. This is not quite correct, and the Chinese have therefore formed a cycle of 60 years, in which period 22 intercalary months occur. Storm and Hurricane Warnings OF THE WEATHER BUREAU, U. S. DEPARTMENT OF AGRICULTURE, STORM WARNINGS. Northeasterly winds. Southeasterly winds. Northwesterly winds. Southwesterly winds. P Red, black centre. Storm Warnings. -A red flag with a black centre indicates that a storm of marked violence is expected. The pennants displayed with the flags indicate the direction of the wind; red, easterly (from northeast to south); white, westerly (from southwest to north). The pennant above the flag indicates that the wind is expected to blow from the northerly quadrants; below, from the southerly quadrants. By night a red light indicates easterly winds, and a white light above a red light westerly winds. Hurricane Warnings. Two red flags with black centres, displayed one above the other, indicate the expected approach of a tropical hurricane, and also one of those extremely severe and dangerous storms which occasionally move across the Lakes and Northern Atlantic Coast. Velocity of Winds in the United States. AVERAGE hourly velocity of the wind at selected stations of the United States Weather Bureau, also the highest velocity ever reported for a period of five minutes. (Prepared by W. L. Moore, Chief of the Weather Bureau, and revised to December 31, 1906, for THE WORLD ALMANAC.) Anemometer blew away, at a velocity of 84 miles per hour, September,1900. †Stations discontinued. STANDARD TABLE SHOWING VELOCITY AND FORCE OF WINDS. From 1890 to 1898 the property loss by tornadoes in the United States was $26,633,750 [See THE WORLD ALMANAC for 1902, page 61]. The number of persons killed by tornadoes 1889 to 1898 inclusive was 1,437. Loss by Lightning in the United States. THE Weather Bureau of the United States Department of Agriculture in October, 1900, issued a bulletin giving these facts: In 1899 the total number of strokes of lightning which caused damage was 5,527; number of buildings injured, 6,256; value of property lost, $3,018,520; number of deaths by lightning during the year, 563; number of persons injured, 820; number of live stock killed in the fields, 4,251; value, $129,955. These are the latest available statistics. The Chronicle Fire Tables record 3,012 fires caused by lightning in the United States in 1902, the property loss occasioned thereby being $3,396,810. These are the latest reported statistics on the subject. |
