212 McGee and Call— Loss of Bes Moines, Iowa. 



by loss, which in turn reposes upon another drift 

 Careful search for fossils was not made ; a number of indi- 

 viduals of the shells enumerated being found in a single clod. 



-Brownish-yellow drift clay, without stratification except as 

 indicated, containing a few sub-angular and rounded pebbles 

 and bowlders, mainly erratic, gradually becoming fine, 

 clean and homogeneous above. Toward the base it yielded 

 a few huge b'.ss-kindchen, a Suri'im-n <>hh'<jua,a, Stenotrema 

 monodon, and several fragments of shells. 



-Irregular and tortuous hands of unusual h".ss-like aspect. 



-An irregularly undulating ochreous band separating the 

 brownish-yellow from the mottled and bluish division of 

 the drift. Obscure toward the extremities, and most dis- 

 tinct medially. 



-Bluish, brownish-blue and mottled drift clay, identical with 

 number 1 except, in color. com aiiiiiiLf bowlders as indicated 

 up to fifteen inches in diameter, rounded sand and gravel 

 bowlders up to ten inches, many erratic pebbles of which 

 several are polished, one Striated, and one cemented to a 

 calcareous concretion, a few local pebbles including bits of 

 coal, a spherical mass ,,f h", S s fifteen inches in diameter, 

 a few cylindrical ferruginous concretions, numerous loss- 

 kindchen and tubelets, and a similar fauna to that of num- 

 ber 10, but with most of the shells crushed and frag- 

 mentary. Below it is contorted, is obscurely interst ratified 

 with bands of loss, and contains intercalated layers and 

 masses of stratified or laminated sand and gravel in which 

 the lamina? are broken and contorted. From A to B, it 

 graduates insensibly into number 10. 



-A well-marked line of division. 



-Brown and yellow sand and gravel, generally coarse, strati- 

 fied and irregularly contorted. Unfossiliferous.
