REPORT OF THE STATE GEOLOGIST. XXV 



the preparation of his report, the amount of his allotment not permit- 

 ting longer field work. At the same time a request was made by the 

 citizens of El Paso that he be sent to examine and report on the prob- 

 abilities of artesian water at that place. He was instructed to make 

 this and a similar investigation at Georgetown, to start his assistants 

 on the preparation of their notes for his use, and to have his report 

 ready as near the 1st of October as possible. 



On the 26th of August he presented his resignation from the Survey, 

 to take effect as soon as his report was prepared. On his return from 

 El Paso he expressed a desire to have his resignation take effect at 

 once, and that he be allowed to make his report when he could, as he 

 wished to enter into business arrangements which his connection with 

 the Survey would prevent and which would pay better than Survey 

 w r ork. This being found impracticable, he presented a physician's cer- 

 tificate on September 26, stating that he was physically unable to make 

 a report, at this time, and on September 30 he presented another resig- 

 nation, to take effect at once without a report. Under the circum- 

 stances this was accepted, under the conditions that he return all his 

 notes, maps, and materials to this office and observe his written agree- 

 ment in regard to the publication of the results. This terminated his 

 connection with the Survey and explains the reason for the non-appear- 

 ance of a report on the region included in this investigation with the 

 present volume. 



He had, as assistants in this work, Messrs. J. S. Stone, J. A. Taff (who 

 was transferred to Prof. Streeruwitz's division in May), L. T. Dashiel, 

 G. H. Eagsdale, and W. T. Davidson, the work of all of whom he fre- 

 quently commended highly in his letters. 



NORTH TEXAS. 



Prof. Cummins was instructed to take up the detailed study of the 

 Coal Measures of the Central Coal Field. His field force was the same 

 as that of the preceding year. 



He first traced the partings between the Permian and Carboniferous 

 to the Brazos Eiver, and the upper part of Coal Seam No. 7, and 

 then made an instrumental section entirely across the Carboniferous 

 from the edge of Throckmorton County southeast by Graham and Mil- 

 sap, and tracing at the same time the outcrop of Coal Seam No. 1 from
