PART VIII 



Annual Report of the Iowa Weather and Crop 

 Service Bureau of 1919. 



CHARLES D. REED, Director 



For convenient reference and comparison with past and future 

 years, this report contains the summaries of the monthly and weekly 

 bulletins of the Iowa Weather and Crop Service in co-operation 

 with the Weather Bureau of the United States Department of Agri- 

 culture for the year 1919. 



Late in the year 1919 co-operation with the Federal Government 

 was extended to include the Bureau of Crop Estimates, U. S. De- 

 partment of Agriculture, through its Iowa Field Agent, Mr. Frank 

 S. Pinney, in the collection of acreage, condition, yield and other 

 crop statistics. The revised acreage table and final tabulated crop 

 summary herein published are the result of this co-operative effort. 



The effect of the weather on crops will, as heretofore, be pub- 

 lished in co-operation with the United States Weather Bureau. 



The regular meteorological, climatological and crop statistical 

 work was maintained with more completeness and efficiency than in 

 1918, though the general condition of unrest among the people 

 caused many persons to cease co-operation with this service and 

 more than usual difficulty was experienced in finding co-operative 

 observers. 



Publications were distributed as follows : Monthly Climatological 

 Data, about 17,000 copies; Weekly Weather-Crop Bulletins, about 

 20,000; Daily Weather Forecast Cards, to 1,514 addresses; and 

 Rural Delivery Slips to 814 addresses. Five hundred copies of the 

 monthly reports are distributed each month through the United 

 States Department of Agriculture Weather Bureau to scientific in- 

 stitutions and libraries in this and foreign countries. 



Daily weather forecasts were distributed by telegraph at the ex 

 pense of the U. S. Weather Bureau to 82 towns. From these towns 

 the forecasts are made available by free telephone to 132,544 sub- 

 scribers, largely rural. 



Frost warnings are sent when necessary during the fruit bloom- 

 ing season to all orchardists in the State prepared to use orchard 

 heaters and who make application in advance for the service.
