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. In French "torchis" has the same meaning or the meaning of a loaf of this material.
Botanical expedition A botanical expedition is a scientific journey or voyage designed to explore the flora of a particular region. The expedition could be specifically designed for exploring the flora, or this could have been a part of studying the natural history of the region. A naturalist or botanist was charged with drawing and describing the flora, collecting specimens of unknown plants in a plant press, and identifying potential economically important plants. On botanical expeditions funded by governments, the plants were often collected by the person in the field, but described and named by a government sponsored scientists at botanical gardens and universities. For example, many of the species collected on the Lewis and Clark Expedition were described and named by Frederick Traugott Pursh.
