[[2]] The case for tropical imperialism is argued by Dr. J. C. Willis (Director of the Royal Botanic Gardens at Ceylon) as follows: "In the present condition of the world the temperate zones cannot get on without the products of the tropics. The latter provide many things, such as rubber, tea, coffee, cinchona, jute, cane-sugar, spices, etc., which are among the necessaries of modern civilised life. The need for these has led to the settlement of Europeans at trading stations in the tropics, at Calcutta, Malacca, Calabar and many other places. Once settled there, the insecurity of the traders and the inefficiency of the natives have led to the conquest of adjacent territories, until now most of the valuable areas in the tropics are in European or American hands." The conquering nations "work on the principle of governing the country for the benefit of the governed; but they must also so arrange matters that the tropical countries shall take their share in the progress of the world at large, and produce and export certain commodities for the benefit of that world which cannot get along properly without them. If the countries of the tropics can be made to progress so far that they shall themselves, with their own population, produce these things, so much the better; but the things must be produced."—"Agricultural Progress in the Tropics,"—Science, London, Vol. V, pp. 48, 49.

[[5]] Historically, of course, this theory was not the real motive behind the Doctrine. That motive was the unwillingness of the United States to have strong, military nations in its immediate vicinity.
[[6]] A failure to meet the requirements of the industrial nations does not necessarily involve a complete extinction of political independence. Any measure of control, any merely reserved right, such as the United States retains in Cuba, may suffice for the purpose.
