My Dear Prof. Osborn:,br> I have just arrived at home having come right through as soon as I came off the Reservation.
The fossils are in good hands with Mr. Maples and I feel confident that he will take the best of care in shipping them. But I have grave misgivings about turning the skull on end or the side. You must remember that the matrix was soft cemented sand and the frill was partly cleaned from matrix were not solid, then cemented and bridged up with timbers. This is solid not having moved a fraction of an inch during the trip now, but throwing all this weight on one side or end might injure the specimen. However, I have written Mr. Maples giving him explicit directions under all conditions of handling.
I think it would be best to urge Mr. Stone to start a furniture car or one having a car door at leat 5 ft 7 ins. in the clear, the width of crate so that we need not run any unncecessary risks.
I will give you a brief account of my trips over the Crow Reservations. The Crow Reservation between the Yellowstone and the Big Horn River consists of a series of table lands nearly horizontal near Billings but rising at an increasing angle to the Pryor and Big Horn Mountains on the West till at head of East Pryor they are raised to an angle of 40 degrees.
Three members of the Cretaceous series are well defined overlying the Jurassic. This formation is exposed on the face of these upturned tables flanking the Pryor Mountains and throughout the course of Beaurais Creek, East Pryor Creek and most of trebutaries of the Big Horn River. The escarpments are quite abrupt along the creeks and bad lands are usually confined to creeks, the tables in most part being grass-covered.
Fossils were found in several places along Beaurais Creek. At Cashen�s farm near the house I located two prospects that continued and beyond point where I stopped digging. One was the tail of a Dinosaur about the size of and resembling Creosaurus of which I exposed eleven vertebrae in fine condition, not crushed.
Some separate vertebrae and two bones were taken to show condition of fossils. At another place about three miles from Cashen �s house on the top of a table exposure ther is a pocket of bones resembling the conditons found at Bone Cabin. It is from this hill that Cahsen took the limb bones now on exhibition in the Billings State Bank.
Several limb bones were found along Beaurais Creek; some in perfect state of preservation while others seemed to have been cracked before fossilization.
The exposures are very limited, confined to creeks and would not warrrant a separate expedition to Montana, but in any opinion should be worked for a short while anyway in conjuction with some other field close by another year.
This briefly is the conditions here. I am trying to write up my report but may not be able to finish it while at home.

Very sincerely yours
Barnum Brown
