Edzvard Drinker Cope. — Frazer. 117 
The cast that is in Paris, which belongs to me is Hyracotherium 
ventielum, and is probably in the Trocadero, where the last Exposition 
material was partly deposited. I want to sell it for $50.00, provided it 
is still in existence. If you could find out for me I would be greatly 
obliged. If you could suggest me some one who would buy it I 
would be doubly so. 
We left our pretty camp with regret, with all the birds that nested 
in the cottonwoods. I also left a pet rattlesnake who lived in a cer- 
tain hole with two entrances, at one or the other of which he wa's 
lying every day as I went to and fro after fossils." * * 
"Madison, South Dak., July 5, 1892. * * The country is mostly 
rich prairie in fact except the Black Hills and the bad lands, this 
entire state is simply grassy prairie." * * 
"Rock Creek Sub-Agency, Grand R. Dak., July 17, 1892. * * 
By noon we reached Miss Collins' house at Little Eagle's settle- 
ment on the Grand. She received us very hospitably and kept us all 
night. Here mosquito bars made life endurable. She is a Massa- 
chusetts woman, has quite a taste for natural history and she has a 
collection and a library. She is much respected by the Sioux, who 
call her Winona, "the first born." * * As it grew late we turned 
down a low hill to the left and climbed a low bench at the foot of an 
opposite hill. I saw a low base bank and lying around white objects. 
I told Oscar to let me out, as I thought I saw bones. Sure enough 
the ground was covered with fragments of dinosaurs, small and large. 
Soon we found water, and stopped for camp. The Sioux boy mo- 
tioned me to him, and showed me a low clay hill 5^ mile S. We went 
to it, passing over fragments of bones all the way. But at the hill 
were numerous bones of giants nearly entire; one could hardly walk 
without stepping on them. Presently I stopped before a curious ob- 
ject buried deeply in the ground, and behold the nearly entire skull of 
a great reptik related to Hadrosaurus, some 3^ feet long. * * In 
the 3 days I collected, I got 21 species of vertebrates, of which 3 are 
fishes, and all the rest reptiles except one mammal. This last is a 
fine thing, the most valuable I procured, and new as to species, at 
least; and it throws important light on systematic questions.' * * 
"Phila., August 2d, 1892. Dear F. I received your card an- 
nouncing your return, while I was in Dakota. From the tenor of 
your letter from Paris, I had supposed that you would have re- 
mained longer. I wrote you to Paris in reply, and perhaps the letter 
has been returned to you by this time. 
I am just back with a booty in 40 cases of remains of Vertebrata. 
Some nice things! *" 
I have your paper criticising the biography of Leidy. I enjoyed it 
considerably, as a work of art. Essentially however, I think the 
memoir is the only rational, or judicial one that has appeared, and 
am not inclined to be hard on its author on account of it. * * 
During 1892 Prof. Cope published thirty-seven scientific 
papers.
