relationships is that the Catamount schist and the Swede Pond 

 quartzite are anticlinally folded, while the Hague gneiss has been 

 overthrust upon the Catamount; the little valley, in which the stray 

 ore was buried, representing the fault line depression. Retracing 

 his steps to the gap between the exposures of the Swede Pond and 

 swinging to the east along the base of the cliff, the writer found a 

 rusty micaceous schist filling the core of the anticline. Identification 

 of this rock is rendered impossible, due to the fact that it is badly 

 weathered, sheared and fractured. 



The tentative vertical section (see figure 22) which is based in 

 large measure upon Professor Chadwick's suggestions, indicates that 

 the rocks are folded, faulted and penetrated by igneous rocks in a 

 complicated manner. The stratigraphy as here disclosed is appar- 

 ently identical with that shown on the Dixon and Faxon properties. 

 The structure, however, is far different, rendering the mining con- 

 ditions less favorable. 



The ore. The graphitic schist is in many respects similar to the 

 Dixon, Faxon, Hague and Hooper ores. There is, however, con- 

 siderable variation, which is shown in the microscopic analyses here 

 tabulated, especially in the amount and in the size of the graphite 

 flakes. The first two columns give analyses of specimens taken 

 from the ore dump. The fine flake rock probably came from the 



top of the bed while the big flake sample represents the central 



portion.
