During the calendar year 1908, 22,280 square miles, or 14,259,200 acres, were 

 surveyed and mapped in detail on a scale of 1 in. to the mile, making the total 

 area surveyed and mapped up to the end of that year 171,787 square miles, or 

 109,943,080 acres. The average cost of the field work in 1908 was $3.33 per 

 square mile. 



In addition to the detailed surveys, there were conducted in 1908 reconnois- 

 sance surveys in parts of North Dakota, Pennsylvania, and Texas, covering a 

 total area of 50,352 square miles, or 32,225,280 acres. The average cost of these 

 surveys was 32 cts. per square mile. 



These reconnoissance soil surveys were undertaken in 1908 in the region west 

 of the one hundredth meridian, work being started both in North Dakota and 

 Texas to determine the character of the soil and crop adaptations in the Great 

 Plains region. Similar work has also been begun in the cut-over timber lauds 

 of the Great Lakes section, and arrangements have been made for the study of 

 the cut-over timber lands of the Puget Sound region in conjunction with the 

 State of Washington. 



A report on the agriculture and soils of Kent, Surrey, and Sussex, A. D. 

 Hai.l and E. J. Russell (London: Bd. Agr. and Fisheries, 1911, pp. VIII + 

 206, pis. Ii2, figs. Jf). — Since the publication of a preliminary report on the soils 

 of Kent and Surrey counties (E. S. R., 14, p. 644) the scope of this survey has 

 been so enlarged as to add Sussex County to the area and to include the general 

 agriculture of the region. The mechanical analyses of the soils previously 

 made at Wye have also been repeated in order to obtain uniformity in the 

 results here reported, there being variations in the method of analysis now 

 followed (sieve and sedimentation) and that adopted in the earlier work. This 

 book, therefore, is a complete and detailed report of a survey of the soils and 

 agriculture of the counties of Kent, Surrey, and Sussex of southeastern Eng- 

 land, and contains chapters on the natural features of the district, its agri- 

 culture, soils, iticluding mechanical and chemical analyses, the relation of soils 

 to crops, and building stones and other economic products. 



The authors have taken the geological formations as the basis of their work, 

 and their experience in the field " goes to show that each formation in the area 

 under consideration gives rise to a distinct soil type, the characteristic com- 

 position of which can further be recognized by making up an average from the 

 mechancal analyses of the samples taken from that formation." The evidence 

 also goes to show that the mechanical analysis " does determine the funda- 

 mental structure of the soils, and that fair agreement may be expected between 

 the composition of samples taken in a particular area." *
