We must employ other means also for the widening of our colonial territory, so that it may be able to receive the overflow of our population. Very recent events have shown that, under certain circumstances, it is possible to obtain districts in Equatorial Africa by pacific negotiations. A financial or political crash in Portugal might give us the opportunity to take possession of a portion of the Portuguese colonies. We may assume that some understanding exists between England and Germany which contemplates a division of the Portuguese colonial possessions, but has never become _publici juris_. It cannot, indeed, be certain that England, if the contingency arrives, would be prepared honestly to carry out such a treaty, if it actually exists. She might find ways and means to invalidate it. It has even been often said, although disputed in other quarters, that Great Britain, after coming to an agreement with Germany about the partition of the Portuguese colonies, had, by a special convention, guaranteed Portugal the possession of _all_ her colonies.
Other possible schemes may be imagined, by which some extension of our African territory would be possible. These need not be discussed here more particularly. If necessary, they must be obtained as the result of a successful European war. In all these possible acquisitions of territory the point must be strictly borne in mind that we require countries which are climatically suited to German settlers. Now, there are even in Central Africa large regions which are adapted to the settlement of German farmers and stock-breeders, and part of our overflow population might be diverted to those parts. But, generally speaking, we can only obtain in tropical colonies markets for our industrial products and wide stretches of cultivated ground for the growth of the raw materials which our industries require. This represents in itself a considerable advantage, but does not release us from the obligation to acquire land for actual colonization.
A part of our surplus population, indeed--so far as present conditions point--will always be driven to seek a livelihood outside the borders of the German Empire. Measures must be taken to the extent at least of providing that the German element is not split up in the world, but remains united in compact blocks, and thus forms, even in foreign countries, political centres of gravity in our favour, markets for our exports, and centres for the diffusion of German culture.
