beaches. The amount of tilt based upon the wave-cut cliff on the 

 " Clifford hill " at 964 and a level on the " Lower Jay hill " with a 

 figure of 997 is 2.71 feet a mile. Relatively small sand plains of 

 this lake are well shown about the town of H'aselton village in the 

 Lake Placid sheet. 



The controlling outlet is unknown, but the writer offers the sug- 

 gestion that it may have been a one-bank channel on the north side 

 of Haystack mountain (Ausable sheet) carrying the waters east, 

 for there is some evidence of water action in that region. 



Lower Jay lake. This lake level is very definite and no ques- 

 tion seems to exist as to its nature, although the " Lower Jay hill " 

 does not show a corresponding level. About Keene there are wave- 

 cut terraces at 930 and 930.5 feet. A well-preserved terrace bottom 

 is located i^ miles south of Upper Jay with an average height of 

 930 feet (see plate 30), and likewise a fine sandy plain on the 

 western edge of the Lake Placid quadrangle which continues on 

 to the Ausable sheet where we find Otis brook flowing on the east- 

 ern edge. Here the altitude is about 940 feet. We have not 

 sufficient data to calculate the amount of tilt. 



Otis lake. The level called the Otis lake is one of the more 

 doubtful levels, as sufficient data are not at hand to determine 

 whether it is a lake feature or a system oi stream terraces. If we 

 take a level that Johnson regards as a stream terrace 1% miles 

 north of Keene at 903 feet and a beach on the " Lower Jay hill " 

 at 917.5 feet, we obtain an unsatisfactory value of 2 feet a mile for 

 the tilt, which of itself seems to cast some doubt upon the glacial 

 lake origin of the level. Errors in the measurements may, how- 

 ever, be a contributing cause for the discrepancy. 



Rocky Branch lake. Rocky Branch lake is recognized on the 

 basis of three terraces around the villages of Upper and Lower 

 Jay, and upon some of the disputed levels. The latter are 1^4 

 miles north of Keene, 858 feet, and on the "Lower Jay hill" at 

 880 feet, giving a tilt of about 3 feet a mile, which is approximately 

 the expected value. Although the outlet is unknown, the terraces 

 are definite in character and thus this level should rank as definitely 

 settled. 



Clifford lake. This is the last and lowest of the levels definitely 

 recognized within the confines of the Lake Placid quadrangle. Its 

 origin is still in doubt, although a warp of 2.70 feet to the mile is 

 indicated by a beach or stream-terrace a mile south of Upper Jay
