The Winds of the United States and Their Economic Uses

Excerpts: At each of the principal telegraphic reporting stations of the Weather Bureau in the United States there is maintained, by use of the most approved apparatus, a continuous record of the velocity and direction of the wind. These records at many of the stations extend back to the establishment of the Government weather-reporting service in 1871, thus furnishing continuous records of wind velocity for the past 40 years. The total number of stations at which a continuous record of wind movement is now maintained by the Weather Bureau is about 200, which, with others that have been in operation during portions of the above period, but discontinued for various reasons, makes it possible to obtain fairly good records of the hourly, daily, monthly, or annual values of the wind movement at about 300 different points well distributed over the United States, and embracing every character of exposure from near the level of the sea to the tops of some of the highest mountains.
