Profe. J. F. Kemp, C. H. Smyth, Jr.. and H. P. Gushing. A 
third excursion, devoted to economic geology, was led by Dr. 
F. J. H. Merrill, examining the salt and cement works, gyp- 
sum mines, and stone quarries, in the region of Syracuse and 
westward. Lastly, an excursion for the field study of the 
moraines, former glacial lakes, and their shore lines and out- 
lets in western New York, was under the direction of Prof. 
H.L. Fairchild. 
The addresses of the vice presidents of sections were given 
on Monday, August 24; and the four following days were al- 
lotted to the reading of papers in the several sections. On 
Thursday afternoon a considerable number of the geologists 
visited the very interesting section of the Hamilton beds on 
Eighteen Mile creek. Finally, on Saturday nearly four hun- 
dred members and friends of the Association visited the Ni- 
agara falls and gorge. They went north along the Canadian 
side by the electric railway near the edge of the precipice 
overlooking the gorge, crossed the river at Lewiston, and re- 
turned by the new railway along the bottom of the gorge on 
the New York side. The electric power for these railways. 
besides much more used in Buffalo, is supplied by the diver- 
sion of a small part of the river above the falls. A geological 
party further devoted the early part of the following week to 
field observations of the Niagara gorge, the Whirlpool, and 
the course of the drift-filled preglacial valley from the Whirl- 
pool northwesterly to St. David's, the depth of which it is 
proposed to test by borings. 
Honor to Prof. Jamj:s Hall. 
In Section E, of which Prof. lien. K. Emerson was vice 
president, and Prof. William North Rice was secretary (in the 
absence of Prof. A. C. Gill, the secretary elect, in Greenland), 
Wednesday afternoon was given to a very impressive series of 
addresses commemorative of Prof. James Hall's completion of 
sixty years of service in the Geological Survey of New York. 
Such an unprecedented record as his is certainly entitled to 
the cordial and most graceful recognition which, upon this 
occasion, it received. The usual audience attending the ses- 
sions of Section E was largely supplemented by prominent 
members from other sections, as well as by eminent citizens of 
the city of Buffalo.
