Mcipping Soils and Alkali. 41 



The table constructed from this data can l)e used directly by 

 interpolation, or preferably a curve should be constructed and any 

 intermediate points picked out from this. 



Form of a soil survey report. — Owing to the large amount of data 

 being collected by the soil-survey parties, it will be necessary to 

 confine the report from each party to about 50 typewritten pages 

 of 250 words each, or 25 printed pages of 500 words each for the 

 Western Division and to about 15 or 20 printed pages for the 

 Eastern Division. The material for the report should be collected 

 and written up, so far as possible, before the party leaves the field. 



An outline of the chapters is given as a guide in the arrangement 

 of the report, and should be followed as closely as circumstances 

 will permit. The number of words to be given in each chapter 

 will be a guide in the preparation of the material and is given as 

 the result of experience in former reports. It is understood of 

 course that the headings will necessarily have to be changed 

 somewhat in different districts, and the relative importance of the 

 different chapters will vary with the locality. This is intended, 

 therefore, simply as a guide in the preparation of the reports, and 

 the number of words should be taken as the maximum to be used 

 except in the case of matters of special importance, which may 

 need fuller treatment. 



The matter should be presented in a terse style, and no more 

 words used than are absolutely necessary to convey the meaning, 

 being careful, however, to treat each subject so that all important 

 phases may be brought out and clearly stated. In order to attain 

 this, the different chapters should be revised several times if neces- 

 sary, so that all important matters may be considered and all 

 unnecessarv words eliminated. A careful consideration of this 

 matter of style in writing is enjoined upon all members of the 

 division charged with the preparation of reports.
