telegraph-cable works at North Woolwich, he returned to Canada, 
and subsequently established himself as a Mining Engineer at Wilkes- 
barre in the anthracite district of Pennsylvania, where he was for 
nearly ten years actively employed in laying out and improving the 
plant and machinery of different colliery-enterprises. In addition, 
he produced some remarkable coloured maps of the highly disturbed 
seams of the different coal-basins, which have become standard 
authorities for consultation on the opening of new workings, and 
have been adopted both by the United States Geological Survey and 
that of the State of Pennsylvania. He had a very thorough know- 
ledge of the principles of colliery-ventilation and the methods of 
dealing with gas and underground fires, and on several occasions 
distinguished himself in the successful leading of rescue-parties 
after explosions and mine-fires. In 1874, with the co-operation of 
the late Mr. E. B. Coxes and Mr. M. Coryell, he inaugurated a 
movement which resulted in the formation of the American Institute 
of Mining Engineers, of which body he served as President in 1882. 
In 1874, he became joint editor, with Dr. R. W. Raymond, of the 
‘Engineering & Mining Journal’ of New York, and shortly after- 
wards assumed the sole charge and proprietorship of that periodical, 
which, under his skilful guidance, has taken a prominent position 
among the technical journals of the world. A more remarkable enter- 
prise was, however, started in 1893 under the title of the ‘Mineral 
Industry: its Statistics, Technology, & Trade,’ in which, year by year 
since that date, the whole field of the world’s mineral production and 
its mining and metallurgical progress have been recorded in a manner 
that was entirely unparalleled in technical literature. Mr. Rothwell 
possessed in a high degree the power of interesting others in his 
work; and of this there can be no better evidence than the long 
list of eminent contributors from all countries whose monographs 
have appeared in the pages of the ‘ Mineral Industry.’ His some- 
what sudden death on April 17th, 1901, has left a gap among the 
leaders of technical literature which it will not be easy to fill. He 
had become a Fellow of this Society in 1897. [ H. B.] 
Geological science, especially in Nottinghamshire, has received a 
severe blow by the loss of Mr. Jamzs Sutpman, whose tragically 
sudden death took place on November 21st last, at the age of 
53 years. Owing to his extremely shy and retiring disposition, he 
was not so well-known outside his own locality as his great abilities 
and wide knowledge merited, for few men with equally restricted 
opportunities have done so much for local geology. While still a
