Phila., September 9, 1891. Dear F. I went to the Congress. 
As an editor I could not ignore it, as I wanted material for various 
reasons. * * Gaudry and Boule and Zittel and Jaeckel spent two of 
the latter days of the Congress at my house here. 
The feature that displeased me most was the fact that the western 
excursion cost the foreigners $265.00 apiece. I would like to know 
about what the same would have cost if the meeting had been held in 
Philadelphia." * * 
During 189 1 Prof. Cope published thirty-nine scientific pa-

"Phila., May 3, 1892. Dear F. Spring has arrived at last after 
many delays and the country is delightful. 
In a day or two I go to N. W. Texas on the Geol. Survey of the 
State to explore the relations of the Permian to overlying beds, and I 
expect to be absent several weeks. I am just finishing up proof read- 
ing of several papers in the Trans, and Proc. of the Am. Philos. Soc. 
has been making an exhibition of himself again. He has 
been redescribing and rediscovering most of my important discov- 
eries in paleontology of Mammalia for the last 10 years! He names 
the order Condylarthra the genus Meniscotherium, etc., and rejects 
my generalization without credit as if they were new. As my work 
has been generally adopted in Europe, — — will find he has given 
himself another serious blow. I give him a review in the May Natur- 
alist. * * You will be interested in learning what a Waterloo befell 
the old Academy ring two weeks ago. The new men there got tired 
of waiting for the erection of the huge building planned by these 
gentlemen, which would absorb all the money and time within reach 
of the Academy for the next 10 years. So they got up a plan to erect 
a wing with funds actually in sight. They were opposed, and when 
the committee reported, there were two reports. * * They were 
totally defeated by large majorities. The new building will be under 
roof by autumn, and next winter will see a campaign to raise funds 
for endowing professorships. 
"The world do move" and the work we carried in 1876, is like to be 
realized in 1893!" * * 
"Espuella, Dickens Co., Texas, May 22, 1892. * * This place is 
about 20 miles E. of the east wall or front of the staked plains. I 
have often wanted to see this region and understand its geology, as 
it furnishes the connecting link between the geology of the center 
and Gulf-Atlantic regions of the continent. We followed up this 
front wall from near Big Springs (125 miles), and will go yet further
