railroad elevatioD at the station. This locality is the highest yet 

 reported within the limits of the State. The highest known shell 

 locality on the eastern side of the Adirondacks in the Champlain 

 valley is at about 346 feet on the Saranac river at Freydenburg's 

 mills. A locality on the Big Chazy river near Mooers is at about 

 the same level. These marine shells occur through the clayey 

 ground in the village of Norwood (Potsdam Junction of the old 

 maps of the State). This elevation of 360 feet agrees very closely 

 according to Professor Coleman with the upper limit of marine 

 shells on the north side of the St Lawrence valley near Brockville 

 in Canada. Professor Woodworth also reports an occurrence of 

 miarine shells in gravel pits along the road between Mooers 

 Junction and Hemingford, Quebec, near the latter place at 

 an elevation of about 270 feet (aneroid). The shells are mostly 

 Saxicava rugosa in an excellent state of preservation. 



The locality on the Big Chazy near Mooers was found this sea- 

 son and has furnished Saxicava rugosa, Macoma calcarea, M. 

 groenlandica, Leda arctica, Yoldia cf. sapotilla, and Balanus sp. 



Marine shells were also observed in a trench in gravels about 1 

 mile west of Perry's Mills at an elevation of about 300 feet. 



Mr William D. Stevenson, customs officer at Mooers Junction, 

 states that he saw shells at a depth of about 8 feet in a well 

 excavated some 15 years ago at McDowell's store near the railroad 

 station art Mooers Junction. There is a marked sand and gravel 

 delta here at an elevation of 280 feet. 



A feAV marine shells {Macoma groenlandica) were also seen this 

 last season in a small sand hillock at an elevation of 300 feet on 

 the north side of Tracy brook in the town of Chazy, where that 

 stream is crossed by the state road from West Chazy to Sciota. 



The latter part: of August and the first part of September were 

 devoted by Professor Woodworth to the completion of the mapping 

 and study of the Mooers quadrangle, the work on which had been 

 far advanced during the preceding season. Search was directed 

 particularly to the finding of marine shells in stream banks and 

 to the tracing of the shore lines which traverse this area. This
