INTRODUCTORY 



The Iowa Year Book of Agriculture for the year 1910 contains 

 fifteen distinct parts. Preceding part one we have reproduced the 

 information and tables contained in the bulletin issued by the U. S. 

 Bureau of the Census, giving advance information on Iowa farms 

 and farm property, live stock, principal crops, and farm expense 

 as it will appear in the thirteenth census of the United States.

 for 1910. It includes the monthly review of the climatology for the 

 year; a monthly summary of weather and crop conditions; the dates 

 of the last killing frosts in spring and the first in autumn ; final 

 climate and crop review for the year; comparative data for the 

 state on temperature and precipitation, and a tabulated crop sum- 

 mary showing estimated production and valuation of Iowa's prin- 

 cipal farm crops. Also a table showing the final estimate on acreage 

 and production of the principal farm crops by counties for the 

 state.

 for the years 1880, 1885 and 1890 and for the years 1896 to 1910
