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 reports on special matters dealing with the physical fea-
tures and mineral deposits of the State. To supply up-to-date infor-
mation it is necessary to continue and revise earlier surveys of differ-
ent areas and mineral products of the State.
