bined years for all districts is 28%. From this figure, variation is 
observed for districts for the combined and individual years, and 
for years for the combined and individual districts. Neither the 
typical ratio nor the dispersion of the ratios is apparent from the 
table. Some notion of these facts is evident, however, from Chart 
3, which shows by groups, irrespective of the separate years and 
districts, the distribution of the ratios. The most common ratio 
is between 21% and 24%. Differences from this amount, how- 
ever, are frequent; there are five ratios falling between 15% and 
18%, and eight which are as much as or more than 36%. The 
form of the distribution about the mode is, of course, the opposite 
of that for ratios of loans and discounts to earning assets; for the 
latter ratios there was greater dispersion below; for the former, 
greater dispersion above the modal amounts. 
The nature (plus or minus) and the amounts of percentage 
variation of the ratios of investments to earning assets—the seven- 
year average, 1919-1925, serving as the base—for all member 
banks in the twelve districts for the years 1919 to 1925 are given 
in Table 13. Although the signs of the deviations throughout are 
opposite to those for the ratios of loans and discounts to earning
