On the heights overlooking the harbor of Mogador, a seaport on the west coast of Morocco, the missionary, in the coolness of the late afternoon, is following the precept of Voltaire by cultivating his garden. He is an elderly Scotchman, spiritually a little weatherbeaten, as having to navigate his creed in strange waters crowded with other craft but still a convinced son of the Free Church and the North African Mission, with a faithful brown eye, and a peaceful soul. Physically a wiry small-knit man, well tanned, clean shaven, with delicate resolute features and a twinkle of mild humor.
