 uted but a very small percentage of the material of this soil. 



On the slopes of the mountain, between the summit and the 

 2000 foot contour, erratics are fairly plentiful. The soil 

 in which the trees and bushes on the slopes of the mountain 

 are growing is similar to that at the summit and consists 

 almost wholly of glacial till. 



In conclusion it may be said that not only on the slopes 

 adjacent to the summit but at the very summit of the mountain

itself are found practically all those data which are usually 

 accepted by glacialists as evidence of ice transgression- — till 

 containing a large percentage of foreign material, erratics, and 

 rounded and striated surfaces preserved on comparatively little 

 decayed rock. 



Other minor summits. — The Hog's Back and the Sugar Loaf 

 mountains stand at a much lower level than Orford and were 

 not specifically examined. 



On Owl's Head at the summit rounded contours were 

 observed on the northern and northwestern slopes, with a steep 

 cliff face, presumably due to the plucking action of the ice, 

 on the southeast [figure 4]. ]STo striae were observed at the 

 summit although the surface is well rounded, the curvature
