By this time at least one station had been located in every county of Maryland
in accordance with the State Geologist's instructions. Hereafter the observations
were made either to fill out large gaps between some of the previous stations or to
verify the marked irregularities in the distribution of magnetism in central Mary-
land which had made itself very apparent by this time.
