The work of the Survey is essentially that of a bureau of informa-
tion. Each year it distributes about four thousand volumes and pamphlets,
about five thousand maps, and makes several thousand manuscript re-
ports on special matters dealing with the physical features and mineral
deposits of the State. To supply up-to-date information it is necessary
to continue and revise earlier surveys of different areas and mineral,
products of the State.
