Sir William Edmond Logan. 89 



reposed in me, in my endeavors to develop the truth in regard 

 to the mineral resources of .the Province ; and in this work none 

 could have been more interested in ray success than the mem- 

 bers of this Institute. "* 



In August, 1857, the American Association for the Advance- 

 ment of Science held its annual meeting in Montreal, and for 

 several months previous Sir William was hard at work getting 

 his museum in readiness to receive his brother geologists. 

 Owing largely to his untiring exertions, the meeting was a most 

 successful one. He himself read two interesting papers, one on 

 the "Huronian and Laurentian Series of Canada," and another 

 on the " Sub-division of the Laurentian Kocks of Canada " 

 After the business of the Association was concluded, accom- 

 panied by Professor Eamsay, who had come over to represent 

 the Geological Society of London, and Professor Hall, he made a 

 Greological tour through New York State. Eeturning from this 

 trip, he spent the autumn months among the Laurentian Eocks 

 of Grenville. Here too, as already mentioned, he continued to 

 work during the season of 1858. 



For several years after this, his time was much taken up with 

 the preparation and publication of the Geology of Canada and 

 its accompanying Atlas, the former of which appeared in 1863, 

 and the latter in 1865. Before these could be completed, how- 

 ever, many facts had to be added to the stock already obtained, 

 and besides a large amount of geological work among the Lau- 

 rentian rocks of Grenville and the rocks of the Eastern Town- 

 'the country, as 



±n 1862, Sir William was again present, in the capacity of 

 Juror, at the London International Exhibition, and again dis- 

 played a large and interesting collection of economic minerals. 

 Another opportunity of seeing his scientific friends in Britain 

 was also afforded him in 1864, when he went to London to 

 superintend the engraving of the Atlas already mentioned. In 

 1866, a geological collection was again prepared for the Paris 

 Exhibition of 1867, and Sir William worked so closely in 

 getting up a geological map to accompany it that he is said to 



this side of the Atlantic," hard at work in the Pictou coal-field, 

 and the results of this season's work constitute the last of his 

 reports. In 1869, he resigned his appointment to Mr. Selwyn, 

 the present Director of the Survey. 



The few remaining years of his life were occupied chiefly 

 with a study of the rocks of the Eastern Townships and por- 

 tions of New England: but, unfortunately, the conclusions at 

 which he arrived concerning them were not published.
