4 The American Geologist. January, 1903. 
a high source must have been very gratifying to young Sel- 
wyn who rose step by step and advanced in favour amongst 
his colleagues and superiors. 
In August 1847 his work lay in the direction of Festiniog 
in which he was associated with Ramsay, Playfair, Jukes and 
Gibbs. This difficult region offered many problems of eco- 
nomic as well as of geological interest and the careful results 
obtained were discussed on the ground and incorporated in 
the classic maps since prepared. The same year Selwyn was 
at Capel Curig, Jukes was transferred to the South Stratford- 
shire coalfield and in writing to Ramsay of Selwyn's work 
Jukes says : — 'Tt so happens that the last time I saw Selwyn, 
we were mutually wishing that you would send us both into 
Stratfordshire together." After leaving Wales however the 
subject of this sketch carried on his investigations in portions 
of Shropshire as far north as the Triassic outline of Frees. 
The friendship that had arisen between Jukes and Selwyn 
in their joint work in Wales grew as years went on; and in 
1848 they communicated a paper to the Geological Society of 
London giving the results of their investigations in North 
Wales.* 
This friendship was kept well alive during all the years 
Dr. Selwyn was director of the Canadian Geological Survey, 
as many of his colleagues of those years can testify, for, when- 
ever difficult points in the stratigraphy and palaeontology of 
different portions of Canada arose and were discussed in a 
forceful and masterly but always courteous and gentlemanly 
manner, he was wont to quote the words of his friend Jukes 
as follows : — "As my friend Jukes always said, Tf the palae- 
ontology does not agree with the stratigraphy, so much the 
wiorse for the fossils.' " 
In 1848 Selwyn's work took him in the Port IMadoc and 
Dolgelly districts of North Wales. There he and Ramsay pur- 
sued their work amid the glorious scenery surrounding the 
heights of Snowdon and the magnificent and bedecked view- 
points of the fopt ranges. In October of that year consider- 
able discussion arose regarding the structure and succession 
at Glaslyn, and thither Sir Henry de la Beche, Edward 
• A. R. Sei,wyn and J. B. Jukes. "Sketch of the structure of the country 
extending from Cader Idris to Moel Siabod, North Wales." Quarterly Journal, 
Geological Society, London, -vol. vi, pp. 300-302, 1848.
