purpose of examining the geological functions and mineral resources
of the State of Maryland with reference to their economic products,
and for the preparation of reports and maps illustrating the character
and distribution of the mineral resources. The Survey also main-
tains a Highway Division under special Acts of the General Assembly.
It likewise carries on work in hydrography, forestry, terrestrial mag-
netism, and the mapping of the agricultural soils in co-operation with
the National Government. The most important feature of this joint
work is the preparation and publication of a topographic map of the
State on the scale of 1 mile to 1 inch.
The Public Highway, known as State Road No. 1, between the cities
