guns was run off the earth." In other words, the lesson of the American Underworld is that the policeman may be a far greater danger to the community than the criminal. Jonathan Wild will always do more harm than Jack Sheppard. The skill and daring of the cracksman makes him a marked man. But _quis custodes custodiet?_ * See 'The World of Graft,' by J. Flint (1901), p. 154. EPILOGUE. A traveller visiting a strange land takes for granted the simpler virtues. He notes with gratitude and without surprise the generous practice of hospitality. He recognises that the husbandman, patiently toiling on his farm, _adscriptus glebae_, holds in his toil-worn hands the destiny of his country. He knows that the excellent work done in tranquil seclusion by men of letters and scholars will outlast the braggart achievements of well-advertised millionaires and "prominent" citizens. Fortunately, such virtues as these are the common inheritance of all peoples. They are not characteristic of this nation or of that. They belong, like air and sunlight, to the whole civilised world. And it is not by similarities, but by differences, that the traveller arrives at a clear picture of a foreign land. Especially in America do the softer shades and quieter subtleties escape the unaccustomed eye. The swift energies, the untiring restlessness, the universal haste, obscure the amenities of life more darkly there than elsewhere. The frank contempt of law and blood, which receives a daily illustration, must needs take a firmer hold of the observer than the peaceful tillage of the fields and the silent acquisition of knowledge. America is unhappy in that she is still making her history, not one episode of which a vigilant and lupine press will suffer to go unrecorded. Graft and corruption stalk abroad, public and unashamed. The concentration of vast wealth in a few pockets results, on the one hand, in a lowering of the commercial code, on the other, in a general diffusion of poverty, These are some of the traits which mark America off from the other nations, and these traits none with a sense of the picturesque can ever overlook.
