“ Pierre is served by the Chicago & North-Western railway; the Missouri is navigable here, but river traffic has been practically abandoned. Among the principal buildings are the state capitol (1909) and the post office building. Pierre has a public library, and is the seat of the Pierre Industrial School (co-educational, opened in 1890) , a government boarding school (non-reservation) for Indian children. The city has a large trade in livestock, and is a centre for the mining districts of the Black Hills and for a grain-growing country. Natural gas is used for lighting, heating and power. ”
