men and women who can afford it; and it is being taken by such men and
women with increasing frequency. It entails no more difficulty than a
similar trip to the Mediterranean--than such a trip which to a learned
and broad-minded observer offers the same chance for acquiring
knowledge and, if he is himself gifted with wisdom, the same chance of
imparting his knowledge to others that is offered by a trip of similar
length through the larger cities of Europe or the United States.
Probably the best instance of the excellent use to which such an
observer can put his experience is afforded by the volume of Mr.
Bryce. Of course, such a trip represents travelling of essentially the
same kind as travelling by railroad from Atlanta to Calgary or from
Madrid to Moscow.

Next there are the travellers who visit the long-settled districts and
colonial cities of the interior, travelling over land or river
highways which have been traversed for centuries but which are still
primitive as regards the inns and the modes of conveyance. Such
travelling is difficult in the sense that travelling in parts of Spain
or southern Italy or the Balkan states is difficult. Men and women who
have a taste for travel in out-of-way places and who, therefore, do
not mind slight discomforts and inconveniences have the chance
themselves to enjoy, and to make others profit by, travels of this
kind in South America. In economic, social, and political matters the
studies and observations of these travellers are essential in order to
supplement, and sometimes to correct, those of travellers of the first
category; for it is not safe to generalize overmuch about any country
merely from a visit to its capital or its chief seaport. These
travellers of the second category can give us most interesting and
valuable information about quaint little belated cities; about
backward country folk, kindly or the reverse, who show a mixture of
the ideas of savagery with the ideas of an ancient peasantry; and
about rough old highways of travel which in comfort do not differ much
from those of mediaeval Europe. The travellers who go up or down the
highway rivers that have been travelled for from one to four hundred
years--rivers like the Paraguay and Parana, the Amazon, the Tapajos,
the Madeira, the lower Orinoco--come in this category. They can add
little to our geographical knowledge; but if they are competent
zoologists or archaeologists, especially if they live or sojourn
