Professor Cuinniins, with the assistance of Mr. Drake, traced out 

 the stratigraphic relations of the beds formerly known as Albany 

 or Colorado with those of the Wichita, and found the former to be 

 simply the direct southward continuation of the latter. Later, Cum- 

 mins and Dumble made a study of the line of Cretaceous capped 

 buttes west of Stonewall in a search for possible Jurassic deposits. 

 This section was continued to the Staked Plains in Garza County, 

 when they turned south to Big Springs. A careful study and large 

 collections were also made of the interesting section at Kent, El Paso 

 County. In the trans-Pecos the work was confined to a trip by 

 Osann and von Streeruwitz for the investigation of the more im- 

 portant eruptives and igneous rocks, of whicli Osann had found 

 specimens in the collections. 



Professor Cragin's work on the Cretaceous collections was con- 

 tinued until June, when he resigned. The study of the Tertiary 

 iuA^ertebrates was continued through the year by Professor Harris, 

 who not onl}^ determined the forms collected by the survey, but made 

 large collections himself, not only in Texas, but also at type localities 

 in Alabama and Mississippi, and after comparison with the collec- 

 tions in Philadelphia, Washington, and that of Mr. Aldrich, installed 

 the entire collection in the museum, leaving it in the best possible 

 shape^for use. He also prepared a monograph on the Texas Tertiary 

 invertebrates, with descriptions and figures of all forms which had 

 been found in Texas. 



Professor Hyatt continued his assistance and had a number of 

 forms from the Double Mountain division or Ui^per Permian horizon 

 for determination, and Prof. E. D. Cope made a number of determi- 

 nations of vertebrate forms collected during the year. Mr. Charles 

 S, Simpson, of the United States National Museum, studied and 

 described the Triassic Unionidae collected by Cummins in Garza 

 County. 



Doctor Melville died in P^ebruary, and Mr. Dickson continued his 

 work until his resignation in August, when the laboratory was 

 closed. 



In addition to the installation of the suite of Tertiary inverte- 

 brates, collections of the land and fresh-water shells and of the birds 

 were also placed in the museum. 



The fifth annual report was prepared and submitted for publi- 

 cation. The printing board deferred action from time to time and 

 finally declined to order the report printed, on account of the de- 

 pleted condition of the State treasury. They also refused permission 

 for printing at private expense. The report comprised the follow-
