institutional and geographical studies as a basis for the investigation
of the development of cities, it yet seems to me that these studies
cannot prove of supreme value to society unless they are accompanied by
a detailed examination of the _natural_ characteristics of all
individuals who have been born into and existed in, or merely dwelt in,
these surroundings. It is not enough to trace out, however accurately,
the various stages of a town's growth from its commencement to the
present time, because _the cause_ of [Page: 126] the evolution of any
city aggregate lies deeper, is in large part animate, and not inanimate,
in character. The value of the surroundings depends at least as much
upon the capacity of the individual citizen, singly and collectively, to
utilise what he or she is brought in contact with as upon the
peculiarities of these surroundings themselves. Place, tradition, social
organisation, individual development, education, are factors in town
evolution that cannot safely be overlooked, and they all vary from age
to age and in place and place.

If it were possible to completely exchange the inhabitants of a large
town in England with those of an equally large town in France two groups
of changes would become more or less rapidly observable: (1) the French
and English citizens would adapt themselves, as far as they desired and
were able, to their altered conditions; (2) the characteristics of both
towns would gradually change, in spite of geographical position, in
response to the altered human needs. Similarly, a town composed of
individuals who are naturally uncultured and unprogressive will tend to
preserve its uncultured and unprogressive characters more than another
that has alert citizens to carry on its activities. Every profession and
every trade tends to foster its own social atmosphere; and towns will
vary with their industrial life, and individuals favourably disposed to
this atmosphere will come to the town, and those unfavourably inclined
to it will leave. _These changing citizens, as they act upon and react
to their surroundings and vary in their powers age by age, are the real
evolvers of the conditions in which they dwell_; hence the citizen must
not be omitted from our study if we are to understand city growth.

In other words, I think that every investigation of civic, and for that
matter country life should be studied from two aspects: (1) to note the
peculiarities, growth and develop
