IJ'-O] SOILS — FERTILIZERS. 123 



Wisconsin ;;l;ici;iti()n. In ^a-nrral, tlu' surlace c't)n.si.sts of broad lv\v[ i)Iains 

 ln'tween belts of gently undulating land. There is no marked relief. The area 

 as a whole'has poor natural drainage. The soils of the county are of glaeial 

 oiigin and are characterized by a deep, rich black color. Loam soils predomi- 

 nate. 



Including peat, nuick, and meadow, 14 soil types of 8 series are mapped, tlie 

 most important of which are the Webster loam, which covers 58 per' cent of 

 liie area, and the Carrington loam covering 'JT.S per cent. It is noted that small 

 areas of alkali soil occur around former ponds and sloughs, and that the salt 

 accumulations are injurious to most cultivated crops. 



Soil survey of Sargent County, N. Dak., F. Z. Hutton, B. H. Hendrick- 

 so.\, M. ThoxMAs, and S. Bustek (U. S. Dept. Ayr., Adv. Sheets Field Opcr. Bur. 

 Soils, 1917, pp. Jfl, fig. 1, map 1). — This survey, made in cooperation with the 

 North Dakota Experiment Station, deals with the soils of an area of .%'},7G0 

 acres iu southeastern North Dakota. The area comprises three physiographic 

 divisions, namely, the Sheyenne Delta, a rolling treeless prairie, 'and an old 

 sandy lake bed. Drainage is poorly established. The soils of the area are of 

 glacial origin. Including dunesand, 27 soil types of 10 series are mapped, of 

 which the Barnes silt loam and the Barnes loam cover 51.3 and 7.1 per cent of 

 the area, respectively. 



Soil survey of Waupaca County, Wis., W. J. Geib, C. LoUNSHUiiY, and 

 M. o. TosTKHun (U. S. Dept. Ayr., Adv. Sheets Field Oper. Bur. Soils, 1017, pp. 

 .5/, fly. 1, UKip 1). — This survey, maile in cooperation with the State of Wiscon- 

 sin, deals with the soils of an area of 48r),7G() acres, situati-d a little east of the 

 center of \\'isconsin. All of the county lies within the region covered by the 

 laie Wisconsin ice sheet. 



The soils range in texture from sand to clay, with a large area of cumulose 

 >oil, and are largely of glacial origin. Including peat, 28 soil types of 10 series 

 are nuipped. Peat occupies the greatest individual area, covering 15.4 per cent 

 of the county. The Gloucester tine sandy loam and the Kewaunee fine sandy 

 loam cover 12.0 and 10.4 per cent of the area, respectively. It is stated that 

 the Gloucester series includes a number of extensive desirable soils. The ijeat 

 land consists of numerous low-lying marshy areas in which the soil consists of 

 organic matter in varying stages of decomposition. Little of the peat area has 

 lieeii reclaimed and used for farming. 



I)eveIoi)ment of unused lands,' H. T. Cory, F. W. Hanna, et al. {U. S. 

 /Inline Represent., 66. Cony., 1. Sess., Doc. 262, pp. 1S4; al)s. in Enyin. Xcirs- 

 licc., S/, {1020), No. 8, pp. 375-377).— This is :i detailed report on possible proj- 

 ects for the reclamation and developmenf of unused lands in the Ignited Stales, 

 which demonstrates that in most of tlie States there are great bodies of unused 

 lands which, with drainage or clearing, can be made available at a compara- 

 tively small cost fur farm.s. 



It is pointed out that by no means are all of the unused lands properly subject 

 to reclamation for agricultural purposes. Some of the swamp and overtlow 

 lands would be far more useful -tis reservoir sites, for flood control, or river 

 regulation. Sctuu^ of the States presenting little opportuiuty for the reclama- 

 tion of either arid, wet, or cut-over lands aff<n'd chances for profitable reclama- 

 tion by fertilization, correction of soil reaction, and proper tillage. Examples 

 of such lands are found in some of the Mississippi Valley States. Attenti^m is 

 called to New England as an extreme case of the local need for agricultural 

 development. It is stated that the largest areas open to colonization in the 

 southern division of the country are the cut-over lands. In this connection, the 

 necessity for drainage and consequent elimination of mosquitoes is emphasized.
