Camp on Hell Creek,
Aug 12th 1902

My Dear Professor Osborn:-

Your letter of July 25th received. I was greatly disappointed to hear that the clausarusus turned out so poorly especially after all the labor and expense of getting it. I bared bones all over he blocks so that it would have been necessary to take our all the bones from the matrix in the field to determine what condition they were in while the femur illusion and pubic which lay in soft sand were in good state of preservation.
I greatly appreciate your criticism and every pound of matrix that we can possibly remove from these specimens will come off though it takes a great deal of valuable time from prospecting.
Quarry number 2 which contained Triceratops sacrum, scapula, humerus ulna, pubis, vertebrae and ribs has been worked out and we had taked Miles.
Quarry No. 1 contains the femur, pubis, part of humerus thigh vertebrae and two undertermined bones of a large Carniverous Dinosaur not described by Marsh. The pubes are about five feet long. I have never seend any thing like it from the Cretaceous. These bones are embedded in flint like blue sandstone concretions and requre a great deal of labor o extricate.
I am now working out Sterholophus skull which is a prize. Associated with skull are humerus, lower jaw, from phanages fibula, tibia and jaws. Part of these bones are in bad condidtion and in previous letter I described condition of skull. Prof Lull or I will go in with skull o measure its safety next week when Brooks leaves us.
Brooks has been with us a little over a month, a fine fellow in camp and has proven useful in our work.
I have received from the Museum five hundred dollars and have spent five hundred and seventy dollars plus some small amounts not in yet not contrary Prof Lull�s salary.
I purchased three good horses, a new wagon and camp squipage which will sell for nearly full value about two hundred and seventy five dollars.
All provisions, lumber and plaster are very espensive so that I go as economical as possible. Plaster costs fine dollars per barrel in Miles City so I use flour paste wherever practical. Please advise me what disposition to make of the outfit at end of season.
I should not advice another seasons work in this immediate locality and itwould seem to me a good plan to explore the musselshell river at end of season. I propose to work out all material in immediate vicininty and then ride out Crooked Creek thirty miles east of here if nothing more shows up in Hell creek.
Will make sections hrough to Missouri River as soon as these three specimens are out of the way which will give you date from Poweder River to the Missouri River as distance of two hundred and seventy Miles noth and south and from Miles City to Porcupine Creek a hundred and two miles east and west.
The invertebrates I have collected will be a valuable acquisition. There is a small bed of leaves near b which I calculate to collect also.
With regards to the Museum staff,
I am,

Sincerely yours,

Barnum Brown
