the report of Richardson in 1856, and the account in the Geology of 

 Canada, 1863. Abundant evidence shows that the island is gradually 

 rising. Professor Bailey continued his work on the Paleozoic rocks 

 of southern New Brunswick. Some areas west of St. John river, 

 formerly mapped as Ordovician, on lithological grounds, are found to 

 contain a rather meager Silurian fauna. Similar areas east of the 

 river are probably of the same age. A systematic examination of the 

 Carboniferous strata of New Brunswick, with a view to the discovery of 

 workable coal has not afforded satisfactory results. Some reconnais- 

 sance work was done in Prince Edward Island by L. W. Watson. H. 

 Fletcher finds that the sedimentary rocks about the Basin of Mines 

 include representatives of all the Paleozoic groups and the Triassic and 

 the Pleistocene. Igneous rocks are abundant, and include the Triassic 

 traps and the intrusive masses of gray granite and gray diorite. The 

 examination of the outcrops of the Horton series has failed to afford 

 data by which its true position could be determined. It is evident, 

 however, that it is below strata corresponding to the Keokuk-St. Louis. 

 But some would place it near the base of the Devonian. E. R. 

 Fairbault worked on the structural geology of the Cambrian gold- 

 bearing slates and quartzites. The auriferous quartz veins in the area 

 examined follow the contact of the bedded slates and quartzites. In 

 places the folding has caused the development of saddle reefs, but the 

 larger number of veins are on the limbs of the anticlines. G. F. 

 Matthew presents, in tabular form the results of his study of the 

 Cambrian rocks of Cape Breton. He shows the completeness of the 

 Cambrian record of the maritime provinces and correlates the forma- 

 tions with those of Great Britain. Extended notes are added on the 

 particulars of the faunas. Dr. Hoffman reports briefly on the chemi- 

 cal and mineralogical work of the Survey. The substantial progress of 

 the mineral industries is shown in the report of E. D. Ingall. A very 

 valuable feature of the report is the index maps of the various 

 provinces showing the areas covered by the various maps published 

 and in preparation, and giving dates of the reports in which the areas 

 are described. J. F. Whiteaves reports on the work in Paleontology. 

 Some of the individual reports seem to indicate lack of experience 

 both in the prosecution of the field work and in the preparation of the 

 report. The smallness of the parties and the large areas covered by 

 some of them, make it impossible to do more than hasty reconnais- 

 sance work.
