The probabilities are, howevei*, that the sediments in this direction become coarser as the shore line is approached, and that the coal beds either thin or entirely disappear. The coal in Foxboro reported by Edward Hitchcock, nevertheless, may be a reappearaiice of the coal on the northern side of the axis. One and a half miles south-southeast from West Mansfield Station, in the Taunton quadrangle, red and gray sandy slates occur with nearly vertical dips striking N. 64^ E., indicating, along with other outcrops described in connection with that atlas sheet, the much steeper southern side of the syncline and the passage to the adjoining anticline. The accom- panying section (fig. 27) represents the known and inferred portions of the structure through the Mansfield area: N. Fig 27.—Section of the Mansfield Goal Measures. The lines represent observed beds and their underground extension A, roolish Hill granitite, B, Wamsutta series, C, Mansfield Junction. D, West Mansfield mines. E, vertical strata south southeast of last. Analyses of two coals met with at depths of about 90 and 850 feet, respectively, in a boring put down near the old Harden mine, have been.
