The author failed to find any traces of a continental glacier, 

 though he examined the glaciation of the eastern extension of the 

 high pre-Carabiian ridge or plateau bordering the Bay of Fundy 

 with some care. On the contrar}^, great masses of decaj'ed rock 

 in situ encumber the northern and north-western flanks of the ridge, 

 while along the valleys of rivers descending from it northwardly 

 strias were found clearly indicating northerly ice movements. Till 

 or Boulder-clay was found wherever there were traces of glacier or 

 iceberg action, and in some places where there were none. Mr. G. 

 Christian Hoffmann (pp. 1 R. to 68 K.) reports uj)on the work carried 

 on in the Laboratory of the Survey, in which he was assisted by 

 Mr. Frank D. Adams,^ and Mi-. R. A. A. Johnston A report upon 

 the Mining and Mineral Statistics of Canada for the year 1888 is 

 supplied by Mr. H. P. Brumell (pp. 1 S. to 93 S.) ; and Mr. E. D. 

 Ingall, Mining Engineer to the Survey, presents his " Annual 

 Report" for 1889 upon the same subject (pp. 1 S. to 123 S.). An 

 " Annotated List of the Minerals occurring in Canada " by Mr. 

 Hoffmann (pp. 1 T. to 67 T.), closes this bulky volume, of which 

 the foregoing brief notice can give but a very inadequate idea. We 

 can only express the hope that the work of the Geological Survey of 

 Canada is duly appreciated by those for whose benefit it is undei'- 

 taken, and that successive Administrations will maintain it in the 

 high state of efficiency it now enjoys. A. H. F. 



III. — Tenth Annual Report of the United States Geological 

 Survey, 1888-89. By J. W. Powell, Director. Parti.— 

 Geology. 1890, pp. 774, plates and maps, xcviii. 



THE present Report, like those which have preceded it, bears 

 the stamp of the high degree of excellence which the Survey 

 has attained under the direction of Major J. W. Powell, with the 

 assistance of a staff which seems to include nearly all the principal 

 geologists of the United States. The field of investigation comprises 

 the whole of the country ; it takes in every formation, from the 

 Pleistocene to the Archa3an, and embraces every branch of the 

 science, whether Stratigraphical, Petrographical or Palgeontological. 

 To give a list only of the different branches of the work, which, as 

 shown in the Director's Report and in that of the Administrative 

 Chiefs, is being carried out in different parts of the country, would 

 more than occupy our space, and we can here only touch on some 

 points of special interest. One of these is the discovery by Dr. C. A. 

 White in certain counties in Texas of a group of rocks, containing 

 an admixture of Palaeozoic and Mesozoic types of fossils belonging 

 to one fauna, which show a conformable passage of the Coal-measures 

 into the Mesozoic series, and thus fills up one of the widest breaks 

 in the geological succession in the United States, viz., that between 

 the Carboniferous and the Jura-Trias. Another series of rocks with 

 similar fossils has also been noticed in Southern Kansas. 



^ Mr. Adams has since been appointed Lecturer on Geology at McGill University, 

 Montreal.
