ing ill Siberia. To introduce electrical prospecting into the geophysical 

 investigations in Siberia, it is essential to speed up the serial production 

 of new equipment. 



Serious attention should be paid to the further development and improve- 

 ment of electrical prospecting methods, the possibilities of which have 

 not been exhausted by work done up to the present. In particular, the energy 

 of research workers should be concentrated on the creation of methods 

 using natural and artificial variable electromagnet fields. These methods 

 can be used to increase the efficiency of electrical prospecting work and 

 also to extend the sphere of application (studies in the regions of permanent 

 frost) of electrical prospecting.
