taking was strongly recommended, and its advantages as a trade route 
between the East and West, pointed out. 
The following extracts taken from a letter by Dr. L. W. Bailey to 
the writer (Dr. Matthew), refers to Dr. Ells’ first geological field work. 
“Ells first joined me as an assistant about the year 1870 (while still a 
student at McGill), afterwards preparing and publishing with me joint 
reports, and still later doing independent work. Our labors, with which 
you yourself were associated, began in Charlotte County, and were after- 
wards extended to embrace all the Southern counties; St. John, King’s, 
Albert and Westmorland, together with Sunbury, Queen’s and York, 
the results being embodied in numerous special reports published by the 
Geological Survey. The Geological boundaries were fixed as well as the 
districts permitted and have not since been materially changed. These 
boundaries, in addition to being clearly marked by the aid of colors 
in the authorized maps of the Geological Survey, were also introduced 
into Loggie’s map of New Brunswick, the authorized map of the Prov- 
ince. ” 
Apart from this earlier work in the Province of New Brunswick, 
Dr. Ells in middle life and in his later years, took up the study of other 
portions of the Dominion, especially in the provinces of Prince Edward 
Island, Nova Scotia and Quebec. Thus in 1882-84 we find him engaged 
in original Geological and Exploration work in the Gaspé Peninsula. 
In the wild, and at that time little known, region of Gaspé was spent the 
greater part of three field seasons, the geological boundaries as then 
determined, remaining unchanged to the present time. Shortly after 
this he undertook a survey of Prince Edward Island and also reported 
on the Geology of Eastern New Brunswick and of Western Nova Scotia. 
In 1886 Dr. Ells turned his attention to the geological exploration 
and mapping of the Eastern Townships of the Province of Quebec ,—an 
area which had at that time become noted through discoveries of Gold 
and Asbestos. Field work subsequently carried on it this region, and 
extending over many seasons, resulted in the publication of numerous 
reports and bulletins dealing with the Geology and Mineral resources of 
that part of Canada. Dr. Ells’ monograph on Asbestos published at 
that time, constituting a standard work for many years. 

During the period of 1890-97, he was at various times occupied in 
all the Provinces of Eastern Canada. His many reports issued during 
these years, deal with the Manganese deposits of Albert Co., New 
Brunswick, the Oil fields of Gaspé, the Mica, Graphite and Phosphate 
deposits of Quebec besides a large amount of purely geological work 
in various parts of these provinces. During this period he also visited 
The Chicago Exposition in 1893 on behalf of the Geological Survey
