. Reports of explorations and surveys, to ascertain the most practicable and economical route for a railroad from the Mississippi River to the Pacific Ocean . SANDSTONE OF BENICIA AND MARTINEZ—LIVERMOREs VALLEY. 5 exposure, and some seams of gypsum were found.

Martinez, July 10.—Left Benicia and crossed the straits of Carquines to Martinez, a smalltown directly opposite. The hill-slopes on this side of the straits are tolerably well woodedwith an evergreen oak, thus contrasting strongly with the barren slopes of the Benicia trees are, however, principally confined to the valleys or depressions of the hill-sides, anddo not obscure the outlines of the hills, which are beautifully curvilinear. The town is builton a nearly level plain, between two ranges of hills, and our first camp was upon this plain, onthe banks of a small brook. In the channel of this stream, an outcrop of sandstone, similar tothat at Benicia, was observed. Its trend was northwest and southeast, approximately. The geological formations of Benicia and Martinez appear to be similar; Martinez is under-laid by sandstone strata resembling those of Navy Point, and they may be regarded as the con-tinuation of the same series.
