INDEBTEDNESS FROM 1900 TO 1913 157
that the amount of privately invested capital rose from £125 to
£150 millions between 1900 and 1913. In order to determine the
amount of the return upon this capital the average rate of
interest upon capital invested during the period was estimated
from various sources, and the computation is presented in the
next table.

The estimates made by Lehfeldt based on the return for prefer-
ence and government stocks issued in London have little bearing
upon the immediate problem ; but they are of interest in marking
the general trend of interest rates during the period, and the
minimum return which might be expected upon capital. The
steady increase in productivity as indicated by the official index
of productive activity, and the ready market which existed for
Australian loan issues, would seem to indicate that a fairly high
relative rate of interest might be expected ; and this was con-
firmed by the analysis of the dividends of twelve representative
companies. The estimate of average yield can, therefore, scarcely
be considered too high in the light of all the circumstances of
the time. It now remains to estimate the total of interest
