be SO long deferred as to qualify their usefulness to us. We 

 were therefore compelled to incur the unexpected expense of 

 engraving these maps on the quadrangle scale and to have a 

 special report prepared to accompany them. In the work on 

 the Elmira quadrangle, it was my desire and plan to cover con- 

 tinuously therefrom in this areal survey the adjoining territory 

 to the north and east, as therein were involved some interesting 

 questions of classification of the rocks and faunas concerning 

 which we had been diligently acquiring data for many years. 

 The outcome of that work in 1902 was disappointing. No data 

 were acquired by the stratigraphers on which even a preliminary 

 areal map could be constructed and I was unable that year to 

 send our more experienced workers into this rather difficult field 

 to check up the determinations of the stratigraphers. In con- 

 sequence therefore we decided to hereafter execute such work 

 ourselves. It is hardly to be expected that geologists whose ex- 

 perience has been restricted to broad reconnaissance in imperfectly 

 known regions can enter anywhere in this State where the rocks 

 have been continuously studied for nearly 70 years and achieve the 

 results required in New York. It is not our desire to encourage 

 such enterprises. We have therefore made a new start this season 

 beginning with the Elmira quadrangle and extending the work in 

 detail north to the Watkins quadrangle. The undertaking has been 

 essentially in charge of D. D. Luther, whose skill in the careful 

 stratigraphic determination of the older rocks in New York is in my 

 judgment not to be surpassed. This work has occupied essentially 

 all of Mr Luther's time, with that of H. S. Mattimore, during the 

 field season of 1903, with the result that the Elmira and Watkins 

 maps are essentially complete and the Ithaca and Waverly sheets 

 fairly covered.
