earnings. In summary, then, it is seen that relatively high time
deposits, in relation to earning assets, are associated with low
gross earnings, high total expense, and low net earnings; and
that relatively low time deposits accompany high gross earnings
(the relation is not marked), low total expense, and high net
sarnings.
But variations in ratios of the total expense and of the earnings
of banks individually or collectively are, of course, attributable

to conditions other than variable amounts of time deposits. This
fact is apparent so far as groups of banks are concerned, from
the detail in Table 117, account being taken of the effect on ex-
penses and earnings of variable ratios of time deposits and of
investments. The amounts in this table indicate that (1) gross
and net earnings ratios are highest in districts having both time
deposits and investments low, while total expense is highest in
districts with time deposits high and investments low; (2) gross
earnings and total expense are lowest in districts having time
deposits below and investments above their respective district
levels, while net earnings are lowest in those in which both time
deposits and investments are relatively high; and ( 3) relatively
large ratios of time deposits and of investments are conducive
