morphism and must have contained some bituminous matter 

 which yielded the graphite. 



In the large area of series 2, the strike so far as recorded is 

 northeast, but at opposite ends of the exposures the dips are 

 opposed to each other. We have, however, too few data at hand 

 to justify conclusions as to structure. Contrary to the usual 

 experience this area of the limestone series is on the hills instead 

 of being in the valleys. 



Series 3, 4 and 5. No anorthosites or gabbros, no paleozoic 

 strata and no trap dikes have thus far been discovered. 



Series 6. Glacial sands and gravels are found in heavy deposits 



throughout the Lake Pleasant valley, but are thin or wanting 



on the higher elevations to the north. Glacial striae were found 



northeast of Speculator, with a northeasterly bearing, just as in 



Wells. 



Indian Lake 



The northern part of Indian Lake was covered in our report 

 for 1897. The southern part is alone taken up at this time. 



Topograph!/. The southern part of Indian Lake township con- 

 sists of three pronounced northeast and southwest ridges with 

 two deeply incised valleys between them. In the southeastern 

 one lies Indian lake, about 7 miles in length — with a maximum 

 width of half a mile. This is the size recently produced by raising 

 the old dam that formerly existed at its lower end, so that an old 

 overflow was included in the lake. It is planned to raise it still 

 farther, so that it will set back into Lewey lake. The present 

 altitude of Indian lake is 1626. From its shores the mountains 

 rise steeply, reaching on the east about 2500 feet as a maximum, 

 but on the west, in Snowy mountain, a maximum of 3903. The 

 valley of Squaw brook, a steep and narrow depression, then inter- 

 venes, and on its western sides the peaks range from 3500 to 

 almost 4000 feet. All this part is wild and not easily accessible. 

 Snowy mountain is the highest in the Adirondacks outside of 

 Essex and Franklin counties. 



Indian Lake township is very sparsely settled. A few houses 

 are found along the highway from North creek to Blue mountain
