64 Thibty-eighth Annual Report oe the 



proper appreciation of its Palaeontology, for the intelligent estimation 

 of its own mineral and economic resources, and its vital relations to 

 adjacent States. Feeling that the reputation of the State was involved 

 in this matter, as well as his own personal reputation, your State Geolo- 

 gist, has sought to overcome the difficulties in the way by availing himself 

 of the co-operation kindly offered by the Director of the United States 

 Geological Survey, to aid in carrying out the original plan of our own 

 survey, and in completing a proper geological map of the State, for 

 publication by the Legislature of New York. 



Some time since Major Powell offered to send a competent man to 

 Albany to color a geological map under my direction. Pursuant to this 

 arrangement Mr. W. J. McGee, one of the geologists in the United 

 States Geological Survey, and a most able geological cartographer, 

 came to Albany to carry out this plan. He also made, with me, seve- 

 ral excursions into the field for the purpose of correcting former obser- 

 vations and of obtaining more accurate data for the completion of a 

 geological map. We have been extremely careful to color no part of 

 the map where the geological structure is not known, or where grave 

 doubts exist regarding the received opinions qf the geological struc- 

 ture and relations. Under this restriction a very considerable portion 

 of the map will remain uncolored, but we shall have the great satisfac- 

 tion of seeing what part of the State is known and what are the limits 

 and extent of the unknown or incompletely determined areas ; — those 

 where critical work must be done before a complete geological map of 

 the State can be presented. 



The advantages of thus leaving uncolored all that is not fully known, 

 or which requires further investigation, as in the instance cited of Sara- 

 toga and Warren counties, as also considerable portions of Washington, 

 Rensselaer and Columbia counties, are that this knowledge may be 

 introduced and expressed upon the map as it shall be ascertained by 

 careful observation. 



By the arrangements thus made I shall be able to present a colored 

 copy of the geological map of the State, restricted as above, during the 

 early part of February, which will be communicated to the Legislature 

 during that month. 



I may state in this place that if the Legislature refuse to order the 

 publication of this map the United States Geological Survey will under- 

 take its publication. I cannnot believe, however, that there remains so 

 little State pride as to permit this ; still there will be, in such case, no 

 other alternative. 



There are many reasons why I greatly prefer to accept the co-opera- 

 tion of the United States Geological Survey instead of leaving the con- 

 trol of the work in the hands of that organization ; and, also, I believe 

 that the Director of the Survey, himself, will fully coincide with me in 

 that opinion. 



By co-operation your work will be better accomplished, it will come 

 before the public as under the auspices of the State authorities, and 

 your State Geologist will be able to work with more freedom, and will 

 be relieved of many burdens and anxieties assumed by him and conse- 

 quent upon his relations with the State, and he will no longer be work- 

 ing as an isolated individual. 



Through this co-operation better influences will be brought to our
