PART XI 



Annual Report of the Iowa Weather and Crop Service 



for 1914 



GEO. M. CHAPPELL, Director 



The object and aim of this report is to place before its readers 

 a condensed summary of the monthly and weekly bulletins, issued 

 by the Iowa Weather and Crop Service, in co-operation with the 

 Weather Bureau of the U. S. Department of Agriculture. It is 

 believed that in this form the matter will be especially valuable 

 and convenient for reference and comparison in future years. 



Eeports have been received regularly each month from 114 co- 

 operative meteorological stations and from the U. S. Weather 

 Bureau stations at Des Moines, Davenport, Dubuque, Charles City, 

 Keokuk and Sioux City, Iowa, and Omaha, Neb. Crop reports 

 were received on the first of June, July, August, September and 

 December, from about 1,400 correspondents, and weather-crop re- 

 ports were received weekly from April to September, inclusive, 

 from 150 correspondents who are well distributed over the State. 



The instrumental equipment at the meteorological stations has 

 been kept up to a high standard, new thermometers, rain gages 

 and instrument shelters being issued to co-operative observers to 

 replace worn out or defective instruments or equipment when- 

 ever necessary. 



There were distributed during the year 23,000 copies of the 

 Monthly Reports, and 35,000 copies of the Weekly Weather-Crop 

 Bulletins. Four hundred and twenty-five of the Monthly Reports 

 are distributed each month through the Weather Bureau, U. S. De- 

 partment of Agriculture to scientific institutions in this and for- 

 eign countries. 



Daily weather forecasts were distributed by telegraph at the 

 expense of the United States Weather Bureau to 76 towns ; by mail 

 to 2,636 addresses: by rural free delivery to 909 addresses, and 

 by free telephone to 95,621 subscribers. Arrangements were made 

 to supply all fruit growers, who were prepared to use orchard 

 heaters in case of frost, with timely warnings. This branch of 

 the work is highly appreciated by orchardists and will, we believe, 

 increase within the next few years. 



The co-operation with the Horticultural Department, Iowa Ex- 

 periment Station, was continued during the year with fairly good 

 results.
