CROSS-SECTIONS OF FIELD There has not been sufficient prospecting within the marble field to establish the maximum thickness of the marble deposits. In the neigh- borhood of Gantts Quarry, where most prospecting with the drill has been done, the following section (figure 11) has been recorded: s. E. /oeo.

About three-quarters of a mile to the northeast of Gantts Quarry the following section (figure 12) holds: N. W. looo'.
