Report of the State Geologist.

sequently undertook some field work for the special purpose of secur- 

 ing certain terebratuloid forms, and some of the more obscure 

 spire-bearing species. This work has been very successful in the 

 acquisition of an extensive collection of these Brachiopoda. Dr. 

 C. Bominger, of Ann Arbor, has also been employed in making 

 some collections with especial reference to the Brachiopoda of 

 the Hamilton group in its exposure upon Lake Michigan, and 

 later in the season among the older rocks of New York and the 

 adjacent parts of Vermont. Some further information of these 

 collections will be gi^en later on. 



Unfortunately the State Museum has no collection of fossils 

 from the Primordial rocks, and since the Brachiopod genera char- 

 acteristic of that horizon are those to be illustrated on the earlier 

 plates of the volume, I made an unsuccessful effort to obtain 

 from the Museum of Comparative Zoology at Cambridge, and from 

 the National Museum at Washington, specimens to illustrate the 

 principal genera of these older rocks. Mr. Geo. F. Matthew, of 

 St. John, New Brunswick, has promised to obtain for the Museum 

 a collection to illustrate the Primordial rocks of that region. This 

 collection has not yet come to hand, and in the meantime Mr. Mat- 

 thew has kindly loaned to us the use of specimens from his own 

 collection, and we have availed ourselves of such other collections 

 as were within our reach. 



At the request of the Secretary of your Board I present the fol- 

 lowing brief account of my itinerary and its results : 



I have visited, among others, the following-named persons and 

 institutions, and have obtained from them much useful material. 



Prof. Brownell, of the Syracuse High School, has furnished a 

 collection of specimens of several genera of Brachiopoda of the 

 Trenton limestone in exchange for other fossils. 



Some interesting specimens of Brachiopoda were obtained from 

 Mr. E. B. Knapp, of Skaneateles. 



Prof. T. B. Stowell, of the High School at Cortland, loaned 

 me some interesting specimens and presented others to the 

 Museum Collection. I also obtained a few specimens from 

 Prof. Lovell, of the Elmira High School. 



President Allen, of Alfred University, with his characteristic 

 liberality, placed in my hands, for use in the volume, all his avail- 

 able specimens of Brachiopoda. 



In Ann Arbor, Michigan, I obtained from Prof. Winchell the
