Overview

Excerpt from Preliminary Report on the Geology of the Common Roads of the United States The effect of the use of land ways on the development of civilization is evidently great. It is easy to see that so long as men trusted to water communication for their commerce they were to a great extent limited in their dwelling places to regions immediately adjacent to the shore of the sea or to the banks of navigable streams or lakes. Even these methods of intercourse were precarious, as they were much affected by storms and in a large part of the earth by the winter ice The result is that those peoples which have depended for their com merce upon navigation only have rarely become numerous or attained a considerable economic development.
