And in the fourteenth hour of that day's travel, we came to a part where the Land Dipt downward into a broad valley; and surely it did be very dark down there, and did be seeming shallow, yet truly of a great deepness; but we went that way, because that it did be a weary long journey to go around the place where the valley did be.
"The Night Land"
William Hope Hodgson
And the way I washt, was that I Dipt my head-piece into the hot pool, and poured the water over me, and rubbed my body very strong with my hands; and there to be, surely, some certain chemical in the water that aided mine efforts; for the water went very smooth under my hands.
