242 TJiC America!} Geologist. October, 1892 
marked on land by our new mountain-chains, and on our shores by our 
active volcanoes. Thence we sweep, in imarji nation, to the fiery eddies 
of the sun, and thonce to the glowing swirls of the nebulai ; and so out- 
wards and upwards to that most glorious septum of all the visible crea- 
tion, the radient ring of the Milky Way. 
Prof. George Darwin, in his address to the section of mathematical 
and physical science at the meeting of the British Association at Birm- 
ingham in 1886, with all the courage of genius, and the authority of one 
of the sons of the prophets, acknowledged that it seems as likely that 
" meteorology and geology will pass the word of command to cosmical 
physics as the converse." Behind this generous admission I shelter 
myself. But I feel absolutely confident that long after the physicists 
may have swept away these provisional astronomical suggestions as 
"the baseless fabric of a vision," there will still remain in the treas- 
ure-house of the geological fold a wealth of abundant material for the 
use of the mathematician, the physicist, the chemist, the mineralogist, 
and the astronomer, of the deepest interest and of the highest value.

Apart from the papers and discussion the recent gathering of 
geologists at Rochester was noteworthy. Though Rochester is 
one of the large and old established cities of the Empire state, yet 
the American Association for the Advancement of Science had 
never before met there, and the recent gathering and its success 
are in great part due to the judgment and activity of Prof. Fair- 
child, of the university, aided by the local committee. 
The region around Rochester is one of considerable geological 
interest and several of the special points were visited by members 
of the Society and of the Section during their stay. This part of 
the annual gathering seems to be assuming more and more prom- 
inence — a fact scarcely to be regretted. To most of the visitors 
as much advantage may be gained by seeing a new locality as by 
spending their time within four walls. Geology is an outdoor
