[In a recent description of the Island o;f Grand Manan, published in the Cana- 

 dian Naturalist, by Professor Bailey, the author makes no mention of a yery 

 remarkable copper-deposit which occurs on the west coast of that Island. The 

 following notice of this deposit is extracted from a report printed for private 

 circulation in the autumn of last year.] 



1. General descriijtion of the Inland : — The Island of Grand Manan 

 is situated near the mouth of the Bay of Fundy, about ten or twelve 

 miles east of the coast of Maine. It extends in a general NNE and 

 SSW direction, its average length being about twenty-one miles. In 

 breadth, it varies from three or four miles in some places, to seven or 

 eight miles in others. A small strip at the extreme south of the island 

 belongs to the State of Maine; but with this exception the whole of 

 the island is included within the Province of New Brunswick. Saint 

 Andrews, the nearest port of the Dominion of Canada, lies about thirty 

 miles to the north-west. 



The eastern coast of the island is comparatively low, and much in- 

 dented in outline, offering several wide bays and more or less sheltered 

 coves with good anchorage. This side of the island contains one or 

 two saw mills, and also a considerable number of detached settlements, 

 chiefly occupied by fishermen. Towards the central part of the island 

 the ground rises abruptly, and the entire western coast presents an 

 almost unbroken line of high basaltic cliffs, rising vertically to a height 

 of from 200 to 250 feet above the sea level. Below this escarpment, 

 with its slides and talus of heaped and broken rock, there is no true 

 beach, but merely a narrow belt of coarse shingle, covered in many 

 places by huge columns and angular masses of basaltic trap which have 

 fallen from the cliffs above. 



The western side of the island, more especially, is densely wooded, 

 and it would thus furnish a practically inexhaustible supply of good 

 timber for mining purposes. Two or three small lakes also occur upon 

 it, and streams emanating from these afford an unfailing supply o^ 

 water. This point may be especially alluded to, as several valuable 

 mining stations, situated on other islands of the Bay of Fundy, are
