Report of the State Geologist. 181 



" A preliminary geological map including a part of the Catskill 

 region, the southern part of New York and adjacent parts of 

 Pennsylvania, to show the relations of the Catskill group to the 

 underlying formations of the Chemung group, Oneonta sandstone 

 and portage group ; combining all the previous observations with 

 the field work of 1881, by Andrew Sherwood, under the direction 

 of James Hall, State Geologist." This map, like all the preceding- 

 records, was never published and still remains in possession of the 

 State Geologist, as a record of field work done and recorded up 

 to the date of 1881. Other maps and portions of maps likewise 

 containing more or less of the records made during all these 

 years remain still in the possession of the State Geologist, and 

 under the present conditions are of no other value than as 

 evidences of progress of work and the dates upon which it was 

 performed. 



The following extract from remarks made before the American 

 Institute of Mining Engineers, will give some idea of the pro- 

 gress of the geological map since 1883 : 



" In 1883 I had combined, upon a small map of the State, the 

 information which we possessed at that time, and communicated 

 the same with my annual report to the Legislature. The report 

 was published in the regular course, but the special appropriation 

 made for the map was vetoed by the Governor. 



" IS'ot discouraged by this untoward and unexpected circum- 

 stance, work was continued, and every effort made to render the 

 map more complete, preparatory to its communication with the 

 next annual report. I brought together all the information 

 within reach, whether published or unpublished, reviewing and 

 revising, as far as practicable, the work done b}^ myself and 

 assistants in southern and south-eastern IS; ew York. 



" Up to the autumn of 1884 I had been working alone, and 

 unaided, without any means whatever from the State, to complete 

 the field work, and to bring together the knowledge which we had 

 gained from various sources, and that which I had acquired from 

 my own investigations and from assistants employed on my per- 

 sonal account, with the purpose to embody the whole in a geo- 

 logical map of the State. At this juncture, and having no one 

 to act as cartographer, Major Powell, with characteristic liber-
