Bousillage Bousillage (bouzillage, bousille, bouzille) is a mixture of clay and grass or other fiberous substances used as the infill (chinking) between the timbers of a half-timbered building. This material was commonly used by 18th century French colonial settlers in the historical New France region of the United States and is similar to the material cob and adobe.

Robert Gray (sea captain) Robert Gray (May 10, 1755 – "circa" July, 1806) was an American merchant sea captain who is known for his achievements in connection with two trading voyages to the northern Pacific coast of North America, between 1790 and 1793, which pioneered the American maritime fur trade in that region. In the course of those voyages, Gray explored portions of that coast and, in 1790, completed the first American circumnavigation of the world. Perhaps his most remembered accomplishment from his explorations was his coming upon and then naming of the Columbia River, in 1792 while on his second voyage.
