During the field season of 1903, 26,543 square miles or 16,987,520 acres were sur- 

 veyed and mapped on a scale of 1 in. to the mile. Prior to that year the total area 

 surveyed and mapped was 33,868 square miles or 21,675,520 acres. The average cost 

 of the work in 1903 was $2.22 per square mile. The accounts of the individual sur- 

 veys include, as heretofore, data relating to the location, history, topography, physi- 

 ography, geology, climate, agricultural conditions, type soils, and crop adaptations. 



During the year the method of printing and distributing the reports of the soil 

 survey was changed as a result of Congressional action providing for the printing 

 and distribution of advance sheets. This, it is believed, will not only greatly facili- 

 tate the publication of the several reports, but will also provide a larger and much 

 more convenient form for local distribution. 



Land: How it is used and abused, J. Long ( Trans. Highland and Agr. Soc. 

 Scotland, 5. ser., 17 (1905), pp. 103-120). — A general discussion of this subject, point- 

 ing out how lands may be utilized to better advantage by more judicious selection of 

 methods of culture and cropping. The utilization of small holdings of the run-down 

 lands in Great Britain for homes for the pauper and vagrant classes is suggested. 



Methods of tillage, old and new, P. M'Connel (Trans. High/and and Agr. 

 Soc. Scotland, 5. ser., 17 (1905), pp. 121-144, figs. 17). — This is a resume of a previ- 

 ous article by the author « on the history and use of tillage implements, including 

 references to the great changes which have occurred during the last 10 or 12 years 

 "in our ideas on plowing and cultivating land, and in our methods of doing the 

 work," more particularly in the British colonies and the United States. The topics 

 discussed are plows and plowing, harrows, cultivators, steam diggers, and motors. 



Influence of plowing and mellowing the soil on its temperature, A. Tolski 

 (Trudui. Opuitn. Lyesn., 1904, No. 2; abs. in Zhur. Opuitn. Agron. [Russ. Jour. Expt. 

 Landw.~\, 5 (1904), No. 5, p. 707). — Observations were made in 1903 in the Borov 

 experiment forest on the temperature of the soil in two clearings, in one of which 

 the soil was plowed and made mellow, while in the other the soil remained unplowed 

 and unmellowed. 



The observations showed that plowing and mellowing promoted a more rapid 

 exchange of heat in the soil. The heating as well as the cooling of the plowed and 

 mellowed soil was considerably greater than that of unplowed soil, the difference 

 between the mean temperatures of the two during the summer reaching 2 degrees 

 and between the extreme maximum temperatures 5 and more degrees. On the
