442 THE PROGRESS OF GEOLOGICAL INVESTIGATION 
probably his best work was accomplished, his eyes were open to 
the natural phenomena which are everywhere presented to him 
who cares to read the story of the earth. 
A full list of his publications has apparently never been pub- 
lished, and the collecting of these in proper order is a duty yet 
devolving upon some one of those with whom he was intimately 
associated in the scientific work which has been and is still being 
carried on in the Acadian provinces. 
Prior to the admission of the eastern provinces into the 
Canadian confederation the work of the Geological Survey did 
not extend east of Quebec. 
Almost the earliest work, however, of the first director, Sir 
William Logan, was the examination and measurement. in 1843, 
of the celebrated Joggins section on the western coast of Cum- 
berland county, embracing a total measured thickness of 14,570 
feet of Carboniferous strata, in which were included a large part 
of the Lower Carboniferous formation, the Millstone-grit, the 
Productive Coal-Measures, and the Upper Carboniferous in part: 
The work so ably done at that early date has since been revised 
by several other workers in the field, notably by Sir William 
Dawson, the results of whose examinations, stated in much detail, 
will be found in the second edition of the Acadian Geology, 
1868. The section as originally published has ever remained as 
the standard basis of classification for the rocks of the Carbon- 
iferous system in the maritime provinces. 
With the advent of Confederation in 1867, the work of the 
Geological Survey was extended to New Brunswick and Nova 
Scotia. In 1868 Sir William Logan and Mr. Edward* Hartley 
began a detailed examination of the coal fields in Pictou county 
which was carried on till the death of the latter at the close of 
1870. The results of these examinations in the Pictou coal-field 
were of the greatest importance, and the coal basin was mapped 
with great accuracy. J 
In consequence of the importance which the gold-fields of 
Nova Scotia had assumed, Dr. Selwyn who had been appointed 
director of the Geological Survey in 1869, made a somewhat
