Thoreau's Journal: 22-Aug-1858
I have spliced my old sail to a new one, and now go out and try it in a sail to Baker Farm. It is a “square sail” some five feet by six. I like it much. It pulls like an ox, and makes me think there’s more wind abroad than there is. The yard goes about with a pleasant force, almost enough, I would fain imagine, to knock me overboard. How sturdily it pulls, shooting us along, catching more wind than I knew to be wandering in this river valley. It suggests a new power in the sail, like a Grecian god. I can even worship it, after a heathen fashion. And then, how it becomes my boat and the river,—a simple homely square sail, all for use not show, so low and broad! Ajacean. The boat is like a plow drawn by a winged bull.
