investment ratios to the three series are summarized in Table 
119, from which it is found that all three series (1) decrease 
when both time deposits and investments increase and (2) in- 
crease when time deposits increase and investments decrease.

One further type of comparison of the ratios of time deposits 
to earning assets with other statistical series should be made 
before closing this section of the discussion. It relates to the 
district ratios of time deposits relative to the average for the 
country as a whole. It is patent that if the ratios in certain dis- 
tricts are above, others are below this level, but it is not apparent 
that the districts with ratios above (or below) this level have 
gross earnings, total expense, and net earnings at the same time 
above (or below) the country averages for the respective series. 
From what has been said, however, it might be assumed, since 
ratios of time deposits to earning assets which are high relative 
to district levels, or which increase from year to year, tend to 
be associated, respectively, with high or with increasing ratios 
of total expense to earning assets, for instance, that districts in 
which the ratios of time deposits to earning assets are higher or 
lower than the country level would tend to have ratios of total 
expense to earning assets higher or lower, respectively, than the 
country level. But such is not the case for all districts holding
