It will be manifest, therefore, that no single office and no single brain had ever comprehended the British Empire as a whole. It was a mixture of growths and accumulations entirely different from anything that has ever been called an empire before. It guaranteed a wide peace and security; that is why it was endured and sustained by many men of the “subject” races—in spite of official tyrannies and insufficiencies, and of much negligence on the part of the “home” public. Like the Athenian Empire, it was an overseas empire; its ways were sea ways, and its common link was the British Navy. Like all empires, its cohesion was dependent physically upon a method of communication; the development of seamanship, ship-building and steamships between the sixteenth and nineteenth centuries had made it a possible and convenient Pax—the “Pax Britannica,” and fresh developments of air or swift land transport might at any time make it inconvenient. STREET IN HONG KONG STREET IN HONG KONG _Photo: Underwood & Underwood_ LXV THE AGE OF ARMAMENT IN EUROPE, AND THE GREAT WAR OF 1914-18 The progress in material science that created this vast steamboat-and-railway republic of America and spread this precarious British steamship empire over the world, produced quite other effects upon the congested nations upon the continent of Europe. They found themselves confined within boundaries fixed during the horse-and-high-road period of human life, and their expansion overseas had been very largely anticipated by Great Britain. Only Russia had any freedom to expand eastward; and she drove a great railway across Siberia until she entangled herself in a conflict with Japan, and pushed south-eastwardly towards the borders of Persia and India to the annoyance of Britain. The rest of the European Powers were in a state of intensifying congestion. In order to realize the full possibilities of the new apparatus of human life they had to rearrange their affairs upon a broader basis, either by some sort of voluntary union or by a union imposed upon them by some predominant power. The tendency of modern thought was in the direction of the former alternative, but all the force of political tradition drove Europe towards the latter.
