In the South Seas is a collection of Robert Louis Stevenson's articles and essays on his travels in the Pacific. In his words: "For nearly ten years my health had been declining; and for some while before I set forth upon my voyage, I believed I was come to the afterpiece of life, and had only the nurse and undertaker to expect. It was suggested that I should try the South Seas; and I was not unwilling to visit like a ghost, and be carried like a bale, among scenes that had attracted me in youth and health. I chartered accordingly Dr. Merrit's schooner yacht, the Casco, seventy-four tons.
