The total activity reported in 1961 of 5,721.8 man-months and $9,925,744 compares with 7,963 man-months and $10,974,000 reported in 1960. This is a decline of 28% in man-months but a decline of only 4.4% in expenditure. Geographically, Europe had the greatest man-months of activity in 1961, followed by Canada, U. S., Africa, and Japan. In 1961 the methods rank in order: 1) magnetic, 2) resistivity, 3) geochemical, 4) electromagnetic, 5) gravity, and 6) induced polarization. Research in 1961 totaled 1046 man-months or 18.28% of the total mining geophysics effort. This compares with 3159 man-months or about 40% of the total activity in 1960. Thus, a decline in mining geophysics research of 66% is indicated for 1961 over 1960. The decline is entirely in government sponsored research since industry increased its number of man-months of research activity in 1961. Cost wise, expenditures for mining research in 1961 were about 50% of those for 1960. Again, this is a result of a decrease in government activity since industry increased its expenditure for research in 1961 over that for 1960.
