92 EXPERIMENT STATION RECORD. 



" It is needless to say that the report is in no sense a legal treatise, but rather an 

 endeavor to collect and arrange such legal decisions as will serve to show the rela- 

 tion of the law to problems which are essentially geological in character. In sum- 

 ming up the general features of this law, I have recorded some observations which 

 present themselves to the student of geology." The paper is divided into 2 chapters: 

 (1) common law rules concerning underground waters, and (2) legislative acts 

 affecting underground waters.

 "The investigation on which this report was based was carried on under the charge 

 of Mr. X. H. Darton as a part of the general investigation of the underground-water 

 resources of the western portion of the United States."

Contributions to the study of drainage, E. Risler and G. Wery {Ann. Inst. 

 Nat. Agron., 2. ser., 4 (1905), No. 1, pp. 5-23, dgms. 4)-— The interrelations of pre- 

 cipitation, temperature, evaporation, and drainage are discussed, with detailed data 

 of observations on this subject. 



Tile drainage, F. W. Taylor {New Hampshire Sta. Bui. 118, pp. 19-48, figs. 12).— 

 This bulletin describes the implements and methods used in tile drainage, as well as 

 the classes of lands needing drainage in New Hampshire and the best methods of 

 handling them. A drainage system put in at the New Hampshire Station is described, 

 and a statement of cost is given. "The classes of land in New Hampshire needing 

 drainage are (1) meadow lands, (2) gently rolling tillable lands, (3) lowlands around 

 swamps or lakes, (4) lowlands adjacent to salt water. Thorough drainage on most 

 lands will cost §35 to §40 per acre. Many lands can be greatly benefited for $15 or 

 $20 per acre." 



Notes regarding sewage disposal at Paris and Berlin (Engin. News, 53 

 {1905), No. 11, p. 285). — A brief review is given of the annual reports of the opera- 

 tion of the sewers and sewage disposal systems of Paris and Berlin for the year 1903. 



It is noted that in neither city at the present time is any untreated sewage dis- 

 charged into the streams. At Paris the greater part of the irrigated land is under- 

 private ownership, taking sewage by agreement, and in general in such quantities as 

 are required by the crops. At Berlin the whole irrigated area is owned by the city. 

 The following comparative data are taken from the reports: 



Statistics of se cage disposal in Paris and Berlin. 



It is stated that of the whole volume of sewage applied to the land at Paris fully 

 one-half reappears in the drains, where it is measured, sampled, and tested regularly 

 as to the degree of purification. It is claimed that these examinations ' ' demonstrate 

 the perfect harmlessness of the waters after their passage through the soil."
