Geology. 526 GEOLOGICAL SURVEY OF THE TERRITOEIES. great uieasuie only estiiaates, as the circumstauces were not altogether ivivorable to the uuiking of accurate measurements. The dip of the strata is about east-southeast, from 3° to 5°, apparently diminishing to the eastward. The bed No. 9 of the section, iu some of its thinner layers, appears to be almost entirely made up of fossil remains, mostly of a species of Melanian, but also a lesser proportion of a species of Viviparus. In places where the rock was decomposed the whole upper surface is cov- ered to the depth of an inch or more with the loose casts of these fossils, which can here be gathered in any quantity, by simply scrai)iug them oft" the Jedges. Other layers below, No. 11, also contain numerous fossils, but in very nuich less abundance, and casts of Unio are found in large numbers, while they are very scarce in the upper strata. Scarcely any fossils were found in the beds other than those specified. In the vicinity of Bitter Greek Station, some four or five miles distant in a general westerly or southwesterly direction, Mr. Meek examined outcrops of some 275 feet of alternat- ing beds of soft grayish and buff sandstones and whit- ish shales and clays, the uppermost of which, judj ing from the dip and strike, must have been as much as 200 feet below the lowest member of the Table Eock section given above. No fossih were found except fragments of fossil-wood j nothing to characterize any of thebeds. An artesian boring at the station penetrated 415 feet through very similar alterna- tions of sandstone, shale, &c.; the most noticeable variation in the rec- Fig. 54- ord. given, being. at the depth of 181 feet of an 18-iuch seam of black carbon aceous shale.
