strata as these, may lead to as brilliant and important results, in 

 the elucidation of geological problems still open, in widening the 

 range of our palaeontological horizon, and in our general knowledge 

 of the history of Life on our globe in all its bearings, as have been 

 reached by the study of the remains of animals of a more substan- 

 tial structure, but which have hitherto been denied to the student 

 of fossil Entomology." 



The following, from Prof. Hind's Report, on glacial striation in 

 New Brunswick, is also of interest, even to those who prefer ice- 

 bergs to glaciers as a means of effecting such striation. 



ACTION OF GLACIAL ICE. 



" Whenever the loose covering of clay and sand is swept off the 

 solid rock throughout the whole extent of this Province, glacial 

 striae are visible ; in other words, the rocks are seen to be polished, 

 striated and sometimes deeply grooved. These striations are obser- 

 ved at all altitudes, but they have been obliterated over wide areas 

 by atmospheric influences. During the past summer I saw them 

 on the summit of Blue Mountain, 1650 feet above the sea. There 

 small surfaces of a very hard metamorphised conglomerate are 

 beautifully polished and striated. They abound throughout the 

 slate region of the Province, the slate receiving with ease and re- 

 taining with much persistency the markings produced by the 

 slowly moving glacial mass. 



" The general direction of these striae is N. 10° W. ; but there 

 are often two sets to be seen, differing in direction by two or three 

 degrees. The best place within a few miles of Fredericton for 

 examining these striae under very singular circumstances, is in 

 Prince William Parish, at and near the antimony mines. On the 

 road to the mines leading from the main post road the striae are 

 beautifully retained on the polished surface of a hard silicious 

 slate. The country in that vicinity has been ground away and 

 removed by ice to a vertical depth of some hundred feet, as has, 

 indeed, a considerable portion of, if not the whole, of the Province. 



" In Prince William, however, an observer can not only see the 

 1 tracks ' of the glacial mass graven on the rocks, but he can also 

 see the work it has accomplished in excavating Lake George. He 

 can trace the course of the glaciers far beyond Lake George (442 

 feet above tide) and Bear Lake ; see it in imagination sweeping 

 jpast the edge of the Plateau of the Carboniferous series, which t
