Then in the autumn of that year, 1858, I was asked to go to the West Indies, and cleanse the Augean stables of our Post Office system there. Up to that time, and at that time, our Colonial Post Offices generally were managed from home, and were subject to the British Postmaster-General. Gentlemen were sent out from England to be postmasters, surveyors, and what not; and as our West Indian islands have never been regarded as being of themselves happily situated for residence, the gentlemen so sent were sometimes more conspicuous for want of income than for official zeal and ability. Hence the stables had become Augean. I was also instructed to carry out in some of the islands a plan for giving up this postal authority to the island Governor, and in others to propose some such plan. I was then to go on to Cuba, to make a postal treaty with the Spanish authorities, and to Panama for the same purpose with the Government of New Grenada. All this work I performed to my satisfaction, and I hope to that of my masters in St. Martin's le Grand. But the trip is at the present moment of importance to my subject, as having enabled me to write that which, on the whole, I regard as the best book that has come from my pen. It is short, and, I think I may venture to say, amusing, useful, and true. As soon as I had learned from the secretary at the General Post Office that this journey would be required, I proposed the book to Messrs. Chapman & Hall, demanding £250 for a single volume. The contract was made without any difficulty, and when I returned home the work was complete in my desk. I began it on board the ship in which I left Kingston, Jamaica, for Cuba,--and from week to week I carried it on as I went. From Cuba I made my way to St. Thomas, and through the island down to Demerara, then back to St. Thomas,--which is the starting-point for all places in that part of the globe,--to Santa Martha, Carthagena, Aspinwall, over the Isthmus to Panama, up the Pacific to a little harbour on the coast of Costa Rica, thence across Central America, through Costa Rica, and down the Nicaragua river to the Mosquito coast, and after that home by Bermuda and New York. Should any one want further details of the voyage, are they not written in my book? The fact memorable to me now is that I never made a single note while writing or preparing it. Preparation, indeed, there was none. The descriptions and opinions came hot on to the paper from their causes. I will not say that this is the best way of writing a book intended to give accurate information. But it is the best way of producing to the eye of the reader, and to his ear, that which the eye of the writer has seen and his ear heard. There are two kinds of confidence which a reader may have in his author,--which two kinds the reader who wishes to use his reading well should carefully discriminate. There is a confidence in facts and a confidence in vision. The one man tells you accurately what has been.
