330 THE ZOOLOGIST. 



in that one area, we proceeded towards the edge of the ravine, 

 some one hundred and fifty yards off to the west. For some 

 distance after the flints had ceased there were no stones or other 

 objects to be found on the ground, but when getting towards the 

 edge we found a few quartz pebbles, which became more numerous, 

 and which we discovered came out of a band of very dark con- 

 glomerate which outcrops and forms the edge of the ravine just 

 there, having withstood the action of the weather better than the 

 soft sandstone. This conglomerate was about fifty feet above 

 the ferruginous band, and appeared to be quite local. All the 

 strata there dip to the east at a very considerable angle, and the 

 dark conglomerate would therefore be a long way below the 

 surface at the place where the flints were found, one hundred 

 and fifty yards away ; while, at the same place, we calculated 

 that the bed of ferruginous conglomerate would be at least, two 

 hundred feet below the surface. 



There is thus no possible connection between the con- 

 glomerates (least of all the ferruginous conglomerate) and the 

 flints which we found ; and, though it might be suggested that 

 they came out of some higher band which had worn down, leaving 

 them on the surface, the circumstances under which they were 

 lying grouped together — evidently the chips from stones broken 

 up on the spot — point to a different conclusion. 



There can be no doubt of the identity of these chips with 

 those described and figured by Dr. Noetling. Mr. LaTouche, 

 who has examined both, tells me that they are exactly alike in 

 appearance, and he cannot detect any difference. They have the 

 same porcelain glaze, are in the same condition, and they were 

 found (though not in the ferruginous conglomerate) in the im- 

 mediate vicinity of the spot where Dr. Noetling found his. Two 

 or three of our specimens are, Mr. LaTouche says, better than 

 any of those found by Dr. Noetling, and more clearly intended 

 for some purpose such as arrow-heads. 



An examination of them shows that they may be roughly 

 divided into irregular lumps and thin flakes. The stone itself is 

 chert, or impure flint, and I do not know for certain from where 

 it was brought. There were no other stones at the place where 

 the pieces were found. There is one obvious core, and there are 

 at least three specimens which seem to be more or less finished
