 The writer visited the West Point dome in 19 16 with Lewis C. 

 Chapman. He was so struck by the symmetry of the dome, the

 The accompanying map (Fig. i) is a result of this survey. Not 

 enough time was available to make the detailed and extensive map 

 which would better express fully the geology of the dome. Traverses
