COMMERCIAL GEOGRAPHY
minor with the greater countries, southern and eastern Europe
follow, and a single chapter is given to each of the remaining
continents. For an elementary text to be used in American
schools it is believed that this allotment of space is wise. The
closing chapter summarizes the history of commerce and sug-
gests some of its larger aspects.
It has been sought to place orderly and cumulative emphasis
on general principles; to concentrate, so far as possible, the
treatment of each topic; to use sparingly statistics of temporary
value ; to give little attention to industrial processes except as
they have geographic meaning; and to present industry and
commerce as organic, evolutionary, and world-embracing, re-
sponding to natural conditions and to the spirit of discovery and
invention, and closely interwoven with the higher life of man.
The illustrations consist of views, diagrams, and maps.
These stand in close relation to the text, and the maps are so
planned that each may exhibit one or a few things in a legible
and simple manner.
The thanks of the author are due to Mr. Chester M. Grover
of the High School of Commerce, Boston, who has read the
proofs and made many welcome suggestions ; and to Mr. R. J. H.
Deloach, Professor of Cotton Industry in the Georgia State
College of Agriculture, who has performed a similar service for
the chapter dealing with cotton. Obligation is acknowledged
also to Professor G. G. Chisholm of the University of Edin-
burgh, whose * Handbook of Commercial Geography” and
whose numerous special papers are useful to every worker in
this field.
Among those who have aided in the illustration of the vol-
ume, thanks are given to The University of Chicago Press for
permission to use several maps from the series of base maps
prepared by Professor J. Paul Goode; to Professor J. McFar-
lane of the Victoria University of Manchester ; Mr. George L.
Buck, Chicago ; Mr. James Warbasse, Gloversville, New York ;
Dr. Charles F. McClumpha, Amsterdam, New York; Dr. L. A.
