The price of this hind at tlie time of the survey (1919) ranged 

 from $225 to $300 an acre. A few well-improved farms with choice 

 locations have sold for $350 to $400 an acre. 



The following table gives the results of mechanical analyses of 

 sami)les of the soil, subsurface and subsoil of the Clarion loam: 



Mechnniral analyses of Clarion loam. 



FAKGO LOAM. 



The surface soil of the Fargo loam is a dark-brown to black loam 

 10 inches deep. The upper subsoil is a dark-brown clay loam to clay, 

 considerably mottled with gray and faintly with j^ellow. Below 28 

 inches the subsoil is a grayish-brown or yellowish-brown clay loam 

 to clay, mottled highh' with gray and showing occasional iron stains. 

 This lower stratum is highly calcareous and contains many small 

 lime concretions. Coarse sand and gravel are found in small quanti- 

 ties throughout the soil profile. 



This soil is developed on the terraces of the Boone River, 2^ miles 

 below its point of entrance into the county. One other area is 

 mapped, in the southeastern corner of the county in section 24, 

 Vernon Township. The total area of the type is only 384 acres. 



This type occupies a flat terrace bench. Owing to its heavy sub- 

 soil it is very retentive of moisture. The soil has a high content of 

 organic matter and produces good yields. 



Included with this tj'pe is a small area of Fargo very fine sandy 

 loam. The surface soil is a dark-brown, mellow very fine sandy loam 

 18 inches deep, and the subsoil a dull-brown to dark-brown silty 

 clay loam. The latter is noncalcareous, contains a relatively high 

 percentage of fine sand particles, and is loamy. This soil lies on the 

 east side of the Boone River, where it enters Hamilton County about 

 2^ miles west and south of Woolstock. It covers about 20 acres, is 

 well drained, and is in cultivation. 



FARGO STT-TY CLAY LOAM. 



The Fargo silty clay loam consists of 6 to 8 inches of black 

 tenacious silty clay to clay loam, underlain by black clay loam con- 

 taining gray mottlings. BeloAv 22 inches the subsoil is a grayish-
