Mack, Colorado, July 27, 1909 Mr. Douglas Stewart Carnegie Museum Pittsburg, Pa. My dear Stewart:- Will you kindly send me -- I was going to ask you to send me Shellac, Gum Arabic &c. but find by telephoning to Grand Junction that it will probably cost less to get it from there. I wish, however, that you would send me a copy of Dr. Hollands Diplodocus paper and a copy of Marsh's Dinosaur monograph. It seems that I have found a good part of the skull of Brontosaurus. I under[stand] that the skull of the beast is unknown though I am not way up on Dinosaurs. This will be good news to Dr. Holland in view of the fact that we expect to have one of the beasts mounted. I will write a letter to Dr. Holland and enclose it unaddressed with this. Will you kindly address to him? After I get this Dinosaur skull out I hope to spend the rest of the season in the Wasatch which gives great promises. Yours in haste, Earl Douglass
