8 ACADIAN GEOLOGY. 



tlic previously published discoveries of Jackson and Alger, but with 

 many additional facts collected by its author in the course of careful 

 examinations of the coasts of the Bay of Fundy, and more hurried 

 journeys in other parts of the province. Gesner's work was of great 

 service in directing popular attention within the province to the subject 

 of geology, and it is still an excellent guide to the localities of in- 

 teresting mineral specimens. "The Industrial Resources of Nova 

 Scotia," a second work by the same author, was published in 1849. 



In 1841, Sir W. E. Logan, now provincial geologist of Canada, made 

 a short tour in Nova Scotia, and contributed a paper on the subject to 

 the Geological Society of London. In 1843, in passing through Nova 

 Scotia on his way to Canada, he visited the South Joggins, and 

 executed the remarkable section which he published in 1845 in his 

 first Report on the Geology of Canada. This section, which includes 

 detailed descriptions and measurements of more than fourteen thousand 

 feet of beds, and occupies sixty-five octavo pages, is a remarkable 

 monument of his industry and powers of observation, and gives a 

 detailed view of nearly the whole thickness of the coal formation of 

 Nova Scotia. 



The year 1842 forms an epoch in the history of geology in Nova 

 Scotia. In that year Sir Charles Lyell visited the province, and 

 carefully examined some of the more difficult features of its geological 

 structure, which had baffled or misled previous inquirers. Sir Charles 

 also performed the valuable service of placing in communication with 

 each other, and with the geologists of Great Britain, the inquirers 

 already at work on the geology of the province, and of stimulating their 

 activity, and directing it into the most profitable channels. The writer 

 of the present work gratefully acknowledges his obligations in these 

 respects. The results obtained by Sir Charles, which much modified 

 and enlarged the views previously entertained of the structure of Nova 

 Scotia, were communicated to the Geological Society, and a popular 

 account of them was given in his " Travels in North America." 



Since 1842, a great number of papers on the geology of Nova Scotia 

 and the neighbouring provinces have been published in the scientific 

 journals and otherwise. The following list includes such of these as 

 have been consulted in the preparation of this work, arranged accord- 

 ing to their dates : — 



On the upright Fossil Trees found at different levels in the Coal Strata 

 of Nova Scotia. Lyell, Geol. Proc. iv. pp. 176-178. 



On the Coal Formation of Nova Scotia, and on the Age of the Gypsum. 

 Lyell, ibid. pp. 184-186.
