646 ECONOMICAL ASPECTS 



office, in order that, so far as possible, their form may be stand- 

 ardized. 



It is also considered that a guide of this description can be 

 used to advantage by the engineer when making his field investi- 

 gations into the projects under examination. A careful study in 

 the field outlined herein, will, as a rule, prevent the overlooking 

 of important data which should be secured on the ground. 



The guide is, therefore, submitted for a dual purpose; first, 

 for use as a framework for the standardization of the test of power 

 reports submitted by field engineers, and second, for use by 

 engineers while in the field as a general memorandum of the 

 various features calling for attention and field study. 



Field investigations vary in character, the majority dealing 

 with the following conditions: (1) Applications for water-power 

 privileges, such applications being unaccompanied by detailed 

 data as to the site of ptream. (2) Applications for water-power 

 privileges accompanied by fairly well-developed plans, setting out 

 the general scheme of development. (3) First-hand investiga- 

 tion of entirely new sites or series of sites, for the purpose of study- 

 ing power, storage and conservation features. 



In preparing the following instructions, the above has been 

 kept in view, and the outline hereunder is intended to serve as a 

 general guide, only such portions being utilized as are directly 

 applicable to the class of report under preparation. It is not 

 intended that these instructions should limit a report solely to the 

 ground covered herein ; much must be left to the discretion of the 

 engineer in charge of the investigations. The points briefly dealt 

 with represent, however, the general important features which 

 require investigation and discussion, in order that the ground may 

 be completely covered.
