accounted for by the scarcity of geographical names in the sparsely 

 settled Adirondacks and that the writer was forced to devote his 

 energies to the graphite properties and did not have the time to go 

 exploring over the country in search of typical outcrops. The names 

 are purely tentative, and nothing more. It is the writer's hope, how- 

 ever, that as continued progress is made in untangling the Grenville 

 series more suitable names and better correlations can be proposed. 

 The practical application of the stratigraphy has already been 

 pointed out. There was hardly a mine that did not have problems 

 that, in a manner at least, were solved by using the knowledge of 

 the succession of the beds. A striking example is the conclusion 

 reached in regard to the amount of ore on the Rowland property. 

 The value is not limited to the question of the amount of ore, but 

 can be used in locating and determining the amount of displacement 

 of faults, "n this connection see the Dixon and Faxon properties.
