jointing and it is of interest to ascertain whether those directions 

 are also the more usual directions of the drainage channels. Since 

 faults have not the prominence that they have to the eastward, 

 they can not have the important effect upon the drainage that 

 they there have. 



The two prominently linear drainage lines of the quadrangle are 

 the Long lake, and the Raquette-Upper Saranac lines. The trend 

 of Long lake throughout its 13! miles of length is closely n. 35 e., 

 nearly half of the lake being on the Blue Mountain quadrangle. 

 Above the lake the Raquette follows the same trend line for at least 2 

 miles more. Below the lake for a mile we have the Raquette and 

 Cold rivers on the same line, beyond which Calkins creek follows it for 

 5 miles more ; in other words for 2 1 miles this is a linear drainage line. 

 Other lines, though shorter and less prominent, have the same trend; 

 the line containing Rock pond, Second and Third Anthony ponds, 

 and their inflowing creeks for one; Grampus and Handsome ponds 

 and the main tributary to Upper Moose creek form another; the 

 Raquette from the mouth of Moose creek to the landing below the 

 falls is equally linear though not quite parallel, the direction being 

 n. 45 e. This is the most prominent drainage direction in the 

 southern half of the quadrangle. It is even more prominent to the 

 southeastward, the Indian lake-Upper Hudson line having the 

 same trend. 



In the northern half of the quadrangle the meridional direction 

 is the more conspicuous. The most prominent line of the sort is that 

 followed by the Raquette river from the falls to Axton, then across 

 to Upper Saranac lake, the valley being blocked by drift sands be- 

 tween the two points. The lake, 7 J miles long and trending north 

 and south is on the same line. Follensby pond, with its inlet and 

 outlet, and the Raquette river below as far as Tromblee's, constitutes 

 another such line. These straight courses would all seem to be 

 determined by lines of jointing, and likely of multiple jointing and 

 slip faulting. It is certainly true that the meridional joint direc- 

 tion is the more important in the northern, and the northeast 

 direction in the southern part of the quadrangle, and these drainage 

 directions are in accord with this. 



The east and west direction for the tributary streams is the more 

 common one in the district, though this prominence is vastly better 

 brought out on the Blue Mountain quadrangle than on the Long 

 Lake. Here the line of Ampersand brook and the Raquette river
