Memoir book containing a captivating and inspiring account of the life of a noted Scottish minister. Written by the reverend himself, this memoir offers a firsthand look at his experiences as a pastor, preacher, and missionary in the seventeenth century; the book contains a mention of a paper boat – “I have been like Children, who with their little Bows shoot, but at no Mark, but that they may shoot; or as when they set their Paper-boats to Sea, but look for nothing else than to see them swim upon the Waters; and so it may be said of them, There is no End of their Labour.” (“Memoirs of the Life of the very Reverend Mr James Fraser of Brea”, 1698, p. 284, James Fraser)
