supply of excellent road metal for the vicinity. Some of the 

 scientific aspects of this rock, which appears to be of volcanic 

 origin, have been described for publication in this report with 

 suitable illustrations. 



He also notes the occurrence of sand-blasted pebbles on an 

 ancient wind-swept delta of the Saranac near Morrisonville, 

 specimens of which have been deposited in the museum. He 

 also sent to the museum the chance find of a crushed Indian 

 skull discovered in the bank on the lake shore of the sand flats 

 between Fort Ticonderoga and the ferry landing. 



Central and Western New York 



Prof. H. L. Fairchild of the University of Rochester has con- 

 tinued his work of the previous year in the study of glacial phe- 

 nomena in central and western New York. 



A belt of moraines lying east of Irondequoit valley was 

 mapped for a few miles. These moraines are significant as 

 probably correlating with the Pinnacle hills (Rochester-Albion 

 moraine), and the study will be continued as opportunity is 

 found. 



In July a few days were spent in the region of Oneida-Rome 

 in reviewing the work of the previous summer and in extension 

 of the study. A few of the observations have been added to 

 the text and maps of the former report which is now in press. 

 Between Oneida and Rome a series of stream channels were 

 studied. These were formed by the eastward flow of waters 

 just previous to the establishment of Lake Iroquois. The New 

 York Central Railroad lies in these channels. They were evi- 

 dently formed at the glacier front, since their north banks are 

 usually lacking. 



The principal work of the summer was in the Lake Erie basin. 

 The ancient beaches parallel with the south shore of the present 

 lake were carefully mapped. In a general way these beaches 

 have been traced by Frank Leverett, G. K. Gilbert and F. B. 

 Taylor, but no detailed maps or descriptions have been pub- 

 lished. The gravel and sand bars were located on the topo- 

 graphic sheets from a point southwest of Ripley, near the State
