MY DEAREST PARENTS,--Every one is writing home to catch the steamer which leaves Rio on Monday. I do likewise, although, so far, I have very little to say to you. You cannot conceive how pleasant it is to feel that tomorrow we shall lie in smooth water at Rio and the horrors of this voyage will be over. O the vile Sea! the damned Deep! No one has a right to write about the "nature of Evil," or to have any opinion about evil, who has not been at sea. The awful slough of despond into which you are there plunged furnishes too profound an experience not to be a fruitful one. I cannot yet say what the fruit is in my case, but I am sure some day of an accession of wisdom from it. My sickness did not take an actively nauseous form after the first night and second morning; but for twelve mortal days I was, body and soul, in a more indescribably hopeless, homeless and friendless state than I ever want to be in again. We had a head wind and tolerably rough sea all that time. The trade winds, which I thought were gentle zephyrs, are hideous moist gales that whiten all the waves with foam.... _Sunday Evening._ Yesterday morning at ten o'clock we came to anchor in this harbor, sailing right up without a pilot. No words of mine, or of any man short of William the divine, can give any idea of the magnificence of this harbor and its approaches. The boldest, grandest mountains, far and near. The palms and other trees of such vivid green as I never saw anywhere else. The town "realizes" my idea of an African town in its architecture and effect. Almost everyone is a negro or a negress, which words I perceive we don't know the meaning of with us; a great many of them are native Africans and tattooed. The men have white linen drawers and short shirts of the same kind over them; the women wear huge turbans, and have a peculiar rolling gait that I have never seen any approach to elsewhere. Their attitudes as they sleep and lie about the streets are picturesque to the last degree.
