known are also still uncolonized, we must increase this area by at least one-half as much more. The latter territory comprises the tropical region, which, with its comparative regularity of climate and generally better soil, is no doubt to prove much the most productive and valuable of the two. The other, with its more precarious features, is, however, on the whole more tolerable to the European constitution.
