Agriculture; Soils; Fruit-culture. ONONDAGA-SALT GROUP. 155 Extent of the red shale in New-York. It is highly probable that it is limited to the district which is indicated by the localities already cited, by which it appears to form a narrow belt running parallel with, but a little south of, the Clinton group, commencing in Herki- mer county, and terminating in Monroe in the vicinity of Rochester. A red shale, spotted with green, rests upon the Oneida conglomerate at the High falls of the Rondout; but this seems to belong to a higher part of the group. The same red shale underlies Becraft's mountain near Hudson. It only shows itself upon the east or northeast side, and then but obscurely. These localities are cited, in order that observers may not be deceived by the strata which so much resemble those of Onondaga county, and which form the base of the plaster and salt deposits. These red beds are probably above both the plaster formation, and that part of the shale which gives origin to the brine springs. 2. Green shale, with the plaster beds. This portion of the group begins with red, green, drab, and yellow-colored shales alter- nating several times ; the green and drab colors, however, predominate, and it is probable the red may be wanting in some places. Like the lowest portion just described, it has the same disposition to decompose after disintegration has taken place. In some limited places, the debris of the rock is lodged upon the shelving and projecting undecomposed parts of the same, like ashes, or in a light powdery condition, and having a strong bitter taste of epsom or glauber salts. This portion, too, when exposed in cliffs, or when penetrated by wells, shows the strata traversed by thin columnar gypsum, either white and translucent
