interesting problems relating to glaciation, geomorpbic cbanges, 

 altered drainage-lines, etc., offering tbemselves for investigation 

 and study in tbis region. 



Dr. J. A. Dresser continued tbe work of previous years by 

 examining and defining tbe copper-bearing rocks of tbe Eastern 

 Townsbips (Sberbrooke district), tbus enabling prospectors to con- 

 fine tbeir labours to tbe productive zones only. Tbe investigation 

 applied mainly to tbe pre-Cambrian rocks, and it was found tbat tbe 

 workable copper is cbiefly restricted to certain igneous portions of 

 tbese rocks. A petrograpbic subdivision of tbe pre-Cambrian strata 

 into volcanic (copper-bearing) and sedimentary rocks was made in 

 conformity witb tbis discovery. 



Tbe completion of tbe study of tbe geology of certain parts of 

 Cbarlotte County, New Brunswick, was undertaken by Dr. R. W. 

 Ells. Tbis work included tbe examination of tbe rocks of Grand 

 Manan Island, and of portions of tbe sbore of tbe Bay of Fund}', 

 between Beaver Harbour and Point Lepreau, wbere, at different 

 places, tbrougb tbe agency of intrusives, tbe ordinary sedimentary 

 rocks of Silurian and Devonian age became altered to tbe condition 

 of scbists of pre-Cambrian aspect. 



Professor L. W. Bailey was occupied in making geological investi- 

 gations in New Brunswick (1) in tbe searcb for fossils in tbe 

 pre-Carboniferous rocks of York and Carleton Counties, and (2) in 

 obtaining information relating to tbe economic minerals of New 

 Brunswick. Tbe study of tlie fossils collected was intrusted to 

 Dr. H. M. Ami, wbose description of tbem forms an appendix to tbe 

 report. Several species of graptolites from tbe black carbonaceous 

 sbales on tbe Tete a Gaucbe Eiver, near Batburst, Gloucester County, 

 New Brunswick, were named, tbeir facies suggesting an Ordovician 

 fauna belonging to one of tbose zones of graptolites occurring on 

 tbe St. Lawrence and Hudson Eivers. Some Bracbiopods from tbe 

 S,W. Miramicbi River were too obscure for specific identity. Tracks 

 of some organism, probably an annelid or otber I'elated form, were 

 found at Tapley's Mill, Woodstock, New Brunswick, in an indurated 

 slate ; to this Dr. Ami gives a new generic and specific name — 

 Eugyrichnites mimitus. The geological origin of tbe slates is not 

 determinable from the evidence at band, but the new designation of 

 tbe fossil is offered for the sake of reference. 



Mr. Hugh Fletcher, witb two assistants, continued field-work in 

 Nova Scotia in the counties of Cumberland, Hants, King's, and 

 Annapolis, including practical researches in the coalfields and iron- 

 ore districts of those counties. A notable discovery was made by 

 Mr. Fletcher, by whose advice a borehole was sunk to tbe depth of 

 2,340 feet, in the shape of a ten-foot seam of coal. This important 

 piece of work opens at once a prospect of finding numerous workable 

 coal-seams throughout a new area fifty miles in length by thirty in 

 breadth. 



A preliminary geological map of the Nictaux and Torbrook iron 

 district of Annapolis County illustrates tbis report. 



Mr. E. R. Faribault was engaged upon a special report on the
