During the past year and a half, the territorial Department of Mines in Alaska has conducted a modest experimental program for the purpose of determining the extent to which magnetic and resistivity methods can be used in interior Alaska in connection with prospecting, mining and geological studies. Since little information is available concerning previous work, and since conditions differ considerably from those in most other regions, it was considered advisable to make a general study of the possibilities and limitation[s] of the two methods, rather than a detailed study of any single problem.
