from district levels. Part III has to do with a study of the rela- 
tions between district series with respect to their variation and 
changes, the purpose of the analysis being to discover the manner 
in which the series are related, to measure the relations, and to 
record and illustrate them. Much of the text is concerned with a 
discussion of the probable occasion for those discovered, and with 
their causal order. This latter phase is best illustrated in Chap- 
ter XIII, in which the conditions making for relatively high or 
low net earnings are considered in detail. 
Part IV utilizes the series of gross earnings, expense, and net 
earnings in the individual banks in the First and Second districts. 
The plan of discussion, while embodying the techniques of both 
Part II and Part III, altered to suit the peculiarities of the data, 
has the purposes of isolating the uniformities, trends, and cor- 
relations for the banks in each of the districts; of comparing them 
in the two districts; and of observing the degree to which they 
characterize banks within and by districts. It is here that fuller 
analysis is accorded a study of the causal order in the relations 
disclosed, Chapter XVII! having to do with ratios of net earnings, 
being especially addressed to this topic. It is here, also, that the 
evidence tending cumulatively to verify the hypotheses back of 
the study is woven together, reviewed, and recapitulated. 
Part V summarizes broadly the conclusions, and presents 
briefly and generally the conditions in the economic, financial, 
and banking system in which an explanation of the phenomena 
discovered is found. 
Such in outline are the plan of study and the methods by which 
it is made. 
4. THE CONCLUSIONS, THEIR NATURE AND SIGNIFICANCE 
It is unnecessary, at this place, to summarize the net results 
of the study in respect to their specific and general character. To 
do the former would be to repeat what is said from time to time 
as the discussion proceeds; to do the latter would be to restate 
material found in Part V. It is sufficient for our present purposes 
to say that the truth of the hypotheses with which the study was 
begun has, it is believed, been demonstrated. There are conclu-
