ary, is 450 feet, a determination first made by Mr Gilbert. As 

 confirming the marine origin of the beaches traced southwest- 

 ward through Sun, Constable and thence to Norwood and Pots- 

 dam, marine shells (Macoma groenlandica) were found at an 

 elevation of 350 feet (aneroid) in bottom deposits £- mile north- 

 east of the railroad junction at Norwood (formerly Potsdam 

 Junction). The highest water line measured in the vicinity of 

 Norwood is 425 feet. These and numerous other data are to 

 be worked out in the office in their relations to the shore lines 

 traced on the east side of the Adirondacks. 



Incidently Professor Woodworth discovered some remark- 

 able slabs of Potsdam sandstone in the town of Mooers, bearing 

 several well preserved crustacean trails (Climactichnites) the 

 location and nature of which have been reported to this office 

 and are discussed in the report of the state paleontologist. 



Of the features mapped on the Mooers quadrangle, attention 

 is specially called to the so called " Flat Rocks," bare areas of 

 the Potsdam sandstone evidently denuded of glacial drift by 

 powerful streams of water forming the drainage of the glacial 

 lakes lying west of the Covey Hill axis. These barren areas 

 are of interest commercially in that they produce large crops 

 of huckleberries, the picking and sale of which forms a con- 

 siderable industry. It is said that over $4000 worth of this 

 fruit was shipped during the past season from Altona alone. 



Professor Woodworth was so fortunate as to meet the party 

 of Canadian and New York State engineers engaged this season 

 in the resurvey of the boundary line from Lake Champlain to the 

 St Lawrence, in charge of Mr C. A. Bigger representing the 

 Canadian government and Mr H. P. Willis, representing the 

 United States, and is indebted to these gentlemen for many 

 favors in the prosecution of his work along the border. He is 

 also indebted to Mr T. H. Henderson jr and Mr Rock, the postmas- 

 ter of Mooers, for information concerning the occurrence of the 

 fossil trails in that town and to Mr William Wray of Alder 

 Bend for assistance in exploring the densely wooded tract on 

 the north slope of Dannemora mountain. 



During the year 1902 Professor Fairchild was in the field 

 for 50 days and carried on his work in central New York
