REPORT OF THE STATE PALEONTOLOGIST 1901 451 



4 Certain suites of fossils which it was thought could be dis- 

 played to best advantage with the least risk and would appeal 

 best to the visiting public. 



In addition thereto, there was prepared for this occasion an 

 illustrated guide to the geology and paleontology of the Niagara 

 falls and gorge. 



With the cooperation of the Buffalo society of natural 

 sciences, I brought together an extensive series of the remark- 

 able crustaceans (Eurypterus, Ptergotus, Eusarcus, Erettop- 

 teriis, Ceratiocaris) which are found in the waterlimes occurring 

 at the well known cement quarries at Buffalo; and it is safe to 

 say that no such collection of these remarkable and interesting 

 objects was ever before brought together in one place. Great 

 credit and much gratitude are due to the generosity of the 

 Buffalo society in allowing their material from these rocks to 

 be exhibited with that of the state museum in the completion 

 of this series. , i 



As a second exhibit of this kind, an extensive collection was 

 prepared, to represent the fossil glass sponges which were, the 

 subject of a recently published state museum memoir. Here 

 again we are placed under many obligations by the great 

 consideration of E. B. Hall of Wellsville, the owner of a large 

 number of characteristic and beautiful specimens of these fos- 

 sils, which we supplemented in a measure with material from 

 the state museum. 



In the preparation of the guide to the geology and paleon- 

 tology of Niagara falls and vicinity, we again had the cooper- 

 ation of the Buffalo society of natural sciences. This 

 work was placed in charge of Prof. A. W. Grabau, 

 who made a special resurvey of the region and some 

 special collections of fossils. The work was designed to 

 treat of the origin of Niagara falls, its history and development, 

 and incidentally the development of the topography of the ad- 

 joining region; a considerable part of the work was devoted to 

 the stratigraphy and the character of the fossils, with abundant 

 illustrations of all the species known to occur in the exposures 

 along the gorge. As a whole the guide seemed well adapted
