 (colored) . 1919. — -Buena Vista County is situated in the northwestern part of Iowa in a prairie 

 region. The topography is flat to gently rolling. Morainic deposits contributed to the more 

 rolling topography. The ruling elevation of the county is 1537 feet above sea level. — The 

 Missouri-Mississippi river drainage divide passes through the county in a general north and 

 south direction. The incipient drainage systems arise in poorly drained areas. Artificial 

 drainage is generally necessary for satisfactory cropping. — Transportation facilities are fur- 

 nished by five railroads.— The mean annual precipitation is 29.80 inches, and is distributed 

 favorably for crops. The mean annual temperature is 46.30°F. The average growing season 

 is 151 days. Numerous low-lying areas are particularly subject to early frost in fall. — Agri- 

 culture which is the principal industry in Buena Vista County consists mainly in the produc- 

 tion of corn, oats and hay and the raising and feeding of hogs, cattle, horses and sheep. 

 Corn is the principal crop. — The soils of the county are mainly of glacial origin. The soils 

 are predominantly dark-colored. In the poorly drained areas the lime content is often high. 

 Alluvial soils are found on the terraces along the Little Sioux River and on the first bottoms 

 of those natural drainage ways of sufficient size to have developed flood plains. Several areas 

 of Muck and Peat are found in the county. — Steep slopes of the glacial soils frequently are for- 

 ested, principally with bur oak, soft maple, elm, basswood and red oak. In the muck and 

 peat areas water loving flora are still to be found in various stages of decomposition. — Eighty- 

 five per cent of the population is rural. Artificial drainage has permitted the extension of 

 the limits of arable land. — F. B. Howe.
