edge, to draw lines of separation accurately between these 

 districts, and for this reason the strata are not herein defined 

 and named as separate formations." 



The remainder of the divisions are sufficiently subdivided 

 for our purposes as given in the above table. Each of the sub- 

 divisions is described and their extent indicated in the text. 

 Following the part on geology is an extensive report on the 

 gypsum of Oklahoma, containing many points of interest to 

 the stratigrapher, especially since the gypsum beds form the 

 principal relief of the upper Red Beds. In the geological 

 part of the report the paleontology of the territory is dis- 

 cussed, and will be referred to later. 



The second of the four papers is the third biennial report 

 of the same survey. I have already reviewed this report, ^^ 

 and will merely call attention to the point of interest to us 

 here. Kirk traced the Wreford limestone of Kansas, and 

 the sandstone (Payne) into which it dissipates, from south- 

 ern Kansas to the vicinity of Norman. It will be seen that 

 the strike of it is such as to pass around the east side of the 

 "Wichita mountains, if traceable all the way, and arrive near 

 the outcrop of the Wichita formation of Texas. It is a mat- 

 ter of considerable importance and it is to be hoped that the 

 Oklahoma geologists will soon be able to trace it out, as it 

 would form an unimpeachable connecting link between the 

 Kansas and Texas Permian. This sandstone lies in the lower 

 part of the Norman division. 



The third of these papers is the "Geology and Water Re- 

 sources of Oklahoma and the Eastern Panhandle of Texas." ^^ 

 In this paper we have the first geological map of the terri- 

 tory, accompanied by a discussion of the formations repre- 

 sented, which seem to be worked out with considerable care 

 for a reconnaissance map, and add greatly to our knowledge 

 of the region. The manner of the gradation of the Kansas 

 light Permian into the red shales and sandstones is shown 

 on this map, the gradual replacement taking place soon after 

 crossing the boundary line.
