812 EXPEEIMENT STATION RECOBD. [Vol.36 



State itself, and an explanatory graph of weighted results as far back as 

 records available would permit; tables giving the monthly rain records at 167 

 specially selected stations vrith monthly and annual averages ; also maps indicat- 

 ing the prevalence of frosts, hail, and rain during the wheat period, namely, 

 April to October; and, finally, as an appendix, the results of meteorological 

 observations taken at the Sydney observatory since 1840." 



Summarizing the records of each district of New South Wales for a period 

 of 44 years, 1871 to 1914, inclusive, it is shown that the average district rain- 

 fall varied from 11.44 in. in the southern portion of the v/estern division to 50.2 

 in. in the north coast division, the former comprising about one-seventh of the 

 whole area of the State. " As the country extends in an easterly and north- 

 easterly direction the rainfall becomes greater, and finally reaches its highest 

 district fall in the neighborhood of the north coast." 



SOILS— FERTILIZERS. 



Analyses of soils of Jones County, W. A. Worsham, Jr., L. M. Carteh, D. D. 

 Long and M. W. Lowby {Bill. Oa. State Col. Agr., No. 93 {1916), pp. 47, figs. 

 2). — This is a report of chemical analyses of the soils of the county to supple- 

 ment the physical survey of the soils made in cooperation with the Bureau of 

 Soils of the U. S. Department of Agriculture (E. S. R., 32, p. 513). 



" Taking the average of all the soils of the county, the analyses show the 

 plant food content to be as follows : Nitrogen 0.0265, phosphoric acid 0.0377, 

 and potash 0.639 per cent." It is stated that while the soils of the county 

 show a rather wide variation in plant food content, the nitrogen content is 

 uniformly low in practically all of them and is the limiting factor of crop 

 production. 



Soil survey of White County, Indiana, T. M. Bushnell and C. P. Erni 

 {U. S. Dept. Agr., Advance Sheets Field Operations Bur. Soils, 1915, pp. J^S, fig. 

 1, map 1). — This survey, made in cooperation with the Indiana State Depart- 

 ment of Geology, deals with the soils of an area of 324,480 acres in northwestern 

 Indiana, the topography of which is generally that of a level to gently undu- 

 lating plain. 



" The northern half of the county is an old lake plain characterized by black, 

 formerly marshy, sandy lands and light sand ridges. The southern half is a 

 glacial plain with low moraines, and includes both timbered and prairie lands. 

 The county is now completely drained by systems of dredged and scraped ditches 

 and by tiles." 



Including muck, 17 soil types of eight series are mapped, of which the Brooks- 

 ton silt loam, Clyde fine sandy loam, Plainfield fine sand, and Clyde silty clay 

 loam cover 19.8, 16.9, 14.2, and 10.6 per cent of the area, respectively. 



Soil survey of Newton County, Missouri, A. T. Sweet, E. S. Vanatta, and 

 E. W. Knobel (U. S. Dept. Agr., Advance Sheets Field Operations Bur. Soils, 

 1915, pp. 41, pis. 3, figs. 2, map 1). — This survey, made in cooperation with the 

 Missouri Experiment Station, deals with the soils of an area of 398,080 acres 

 in southwestern Missouri. "Approximately one-third of the county consists 

 of almost level to gently rolling uplands, a considerable proportion is embraced 

 in stream flood plains and terraces, and the remainder includes gently rolling 

 to rough, hilly land." 



The soils of the county are of residual and alluvial origin. Twelve soil types 

 of 10 series are mapped, of which the Baxter gravelly loam, Lebanon silt loam, 

 and Gerald silt loam cover 34.3, 19.3, and 10.9 per cent of the area, respec- 

 tively.
