Mrs. Josephine Butler, in their world-wide influence for purity, needs no eulogy from our pen. It is known to the world. May Americans strive with equal energy against conditions far more hopeful of amendment, and we will be content to leave the issue with God. It was our purpose when we undertook the task of writing a sketch which would enable Americans to understand the social conditions that are being introduced into our midst from the Orient, merely to make a concise, brief statement of social conditions in Hong Kong out of which these have grown, drawing our information from State Documents of the British Government that we have had for some time in our possession, and of which we have made a close study, as well as from our own observations of the conditions themselves as they exist at Hong Kong and Singapore. But almost at once we abandoned that attempt as unwise because likely to prove injurious rather than helpful to the object we have in view. The facts that we have to relate form one of the blackest chapters in the history of human slavery, and slavery brought up to the present time. Our statements if standing merely on our own word would be met at once with incredulity and challenged, and before we could defend them by producing the proof, a prejudice would be created that might prove disastrous to our hopes of arousing our country to the point of exterminating this horrible Oriental brothel slavery by means of which even American men are enriching themselves on the Pacific Coast. Therefore we have felt obliged to produce our proof at once and at first, and after that, if needed, we can write a more simple, concise account, in less official and less cumbersome form, more suitable for the general public to read,--not that the case could be stated in purer or cleaner language than that used in the quotations from official statements and letters, but the language might be more suited to public taste. But worth cannot be sacrificed to taste, and, as we have said, we feel compelled to publish the matter in its present form first of all. We send it forth, therefore, with the earnest prayer that, while the book itself may have a limited circulation, yet, through the providence of God, it may arouse some one to attempt that which seems beyond our powers and opportunity,--some one who will feel the call of God; who has the training and the ability; some one who has the spirit of devotion and self-denial; some one of keen moral perceptions and lofty faith in the ultimate triumph of justice, who will lead a crusade that will never halt until Oriental slavery is banished from our land, and it can no more be said, "The name of God is blasphemed among the heathen because of you." The documents from which we have quoted so extensively in this book are the following: "_Correspondence Relating to the Working of the Contagious Diseases Ordinances of the Colony of Hongkong_." August 1881. C.-3093.
