sheet by the 640 foot contour line. The loose rubble which 

 mantles its surface, particularly on the east, is strongly suggestive 

 of wave action. From this locality westward up the slope of 

 Rand hill the surface is till-covered, becoming morainic in char- 

 acter, with kettle holes indicating the deposition of much glacial 

 drift in the presence of melting ice. 



Throughout the entire length of the Mooers district but few 

 positive traces of wave action occur between the 500 and 600 

 foot contour lines. Along the road parallel with the inter- 

 national boundary, in the district locally kuown as Armstrong's 

 bush, there are no marks between 540 and 620 which can be 

 attributed to wave action, nor are any phenomena of the sort 

 observed except for the slight indications below noted till one 

 passes south of Bovington brook near West Chazy. The pos- 

 sible exceptions are the weak signs of wave action north of the 

 English river between 510 feet and 515 feet, the weak beaches 

 on the hill midway between Sciota and West Chazy at eleva- 

 tions of 540, 550, and a possible case at 590 feet. This ridging 

 of the drift at 590 feet occurs also about a mile and a half west 

 near the margin of the Altona Flat Eock area, with a 600 foot 

 ridge immediately west of it. 



On the road from West Chazy to Cobblestone hill, possible 

 wave marks occur at 540 feet, 545 feet, and again on the eastern 

 and northern slopes of the low hill marked by the 580 foot line. 

 Along the eastern base of Cobblestone hill and northward to- 

 ward the edge of the Flat rock area, there are beach levels con- 

 tinuous in series with the Cobblestone hill group from 610 feet 

 down to at least 590 feet. 



South of the Little Chazy river, there is an apparent beach 

 north of the main branch of Ferrel brook at about 530 feet 

 (from the map). Another narrow beach ridge with a hook at 

 its northern end occurs along the road going south from West 

 Beekmantown at about 550 feet according to the local contour; 

 and southwest of this town the 500 foot contour line apparently 

 follows the crest of an offshore bar. 



Between Silver creek and the south branch of Ferrel brook, 

 there is a marked sandy bar rising on its eastern face from the
