I have stated the case thus: No nation could gain any advantage by the conquest of the British Colonies, and Great Britain could not suffer material damage by their "loss," however much this would be regretted on sentimental grounds, and as rendering less easy a certain useful social co-operation between kindred peoples. For the British Colonies are, in fact, independent nations in alliance with the Mother Country, to whom they are no source of tribute or economic profit (except in the way that foreign nations are), their economic relations being settled not by the Mother Country, but by the Colonies. Economically, England would gain by their formal separation, since she would be relieved of the cost of their defence. Their loss, involving, therefore, no change in economic fact (beyond saving the Mother Country the cost of their defence), could not involve the ruin of the Empire and the starvation of the Mother Country, as those who commonly treat of such a contingency are apt to aver. As England is not able to exact tribute or economic advantage, it is inconceivable that any other country, necessarily less experienced in colonial management, would be able to succeed where England had failed, especially in view of the past history of the Spanish, Portuguese, French, and British Colonial Empires. This history also demonstrates that the position of British Crown Colonies, in the respect which we are considering, is not sensibly different from that of the self-governing ones. It is not to be presumed, therefore, that any European nation would attempt the desperately expensive business of the conquest of England, for the purpose of making an experiment with her Colonies which all colonial history shows to be doomed to failure. What are the facts? Great Britain is the most successful colonizing nation in the world, and the policy into which her experience has driven her is that outlined by Sir C.P. Lucas, one of the greatest authorities on colonial questions. He writes, speaking of the history of the British Colonies on the American continent, thus: It was seen--but it might not have been seen had the United States not won their independence--that English colonists, like Greek Colonies of old, go out on terms of being equal, not subordinate, to those who are left behind; that when they have effectively planted another and a distant land, they must, within the widest limits, be left to rule themselves; that, whether they are right, or whether they are wrong--more, perhaps, when they are wrong than when they are right--they cannot be made amenable by force; that mutual good feeling, community of interest, and abstention from pressing rightful claims to their logical conclusion, can alone hold together a true Colonial Empire.
