Commerce is simply and purely the exchange of one product for another. If the British manufacturer can make cloth, or cutlery, or machinery, or pottery, or ships cheaper or better than his rivals, he will obtain the trade; if he cannot, if his goods are inferior or dearer, or appeal less to his customers, his rivals will secure the trade, and the possession of _Dreadnoughts_ will make not a whit of difference. Switzerland, without a single _Dreadnought_, will drive him out of the market even of his own colonies, as, indeed, she is driving him out.[14] The factors which really constitute prosperity have not the remotest connection with military or naval power, all our political jargon notwithstanding. To destroy the commerce of forty million people Germany would have to destroy Britain's coal and iron mines, to destroy the energy, character, and resourcefulness of its population; to destroy, in short, the determination of forty million people to make their living by the work of their hands. Were we not hypnotized by this extraordinary illusion, we should accept as a matter of course that the prosperity of a people depends upon such facts as the natural wealth of the country in which they live, their social discipline and industrial character, the result of years, of generations, of centuries, it may be, of tradition and slow, elaborate, selective processes; and, in addition to all these deep-seated elementary factors, upon countless commercial and financial ramifications--a special technical capacity for such-and-such a manufacture, a special aptitude for meeting the peculiarities of such and-such a market, the efficient equipment of elaborately constructed workshops, the existence of a population trained to given trades--a training not infrequently involving years, and even generations, of effort. All this, according to Mr. Harrison, is to go for nothing, and Germany is to be able to replace it in the twinkling of an eye, and forty million people are to sit down helplessly because Germany has been victorious at sea. On the morrow of her marvellous victory Germany is by some sort of miracle to find shipyards, foundries, cotton-mills, looms, factories, coal and iron mines, and all their equipment, suddenly created in order to take the trade that the most successful manufacturers and traders in the world have been generations in building up. Germany is to be able suddenly to produce three or four times what her population has hitherto been able to produce; for she must either do that or leave the markets which England has supplied heretofore still available to English effort. What has really fed these forty millions, who are to starve on the morrow of Germany's naval victory, is the fact that the coal and iron exported by them have been sent in one form or another to populations which need those products. Is that need suddenly to cease, or are the forty millions suddenly to be struck with some sort
