Herbert G. Ogden, Geography of the Land
“ From what regions of the continent the future wealth is to be derived we cannot predict. The uncertainty is, perhaps, the consideration in the problem of development that leaves vast areas with undefined boundaries, though nominally within the sphere of influence of a specified power. There are fully 2,000,000 square miles yet to be explored before we may know the general geographic features of the continent, and a much larger area that must be examined and studied by experts before any reasonable estimate of its value and adaptability to the schemes of civilized man can be approached. ”
