Dear Sir: -

I sent you last evening, as you requested, a number of documents for use in your article. Among these was the paper on brain growth, the two stories we agreed upon, and two or three notes which explain themselves.

In the darky story, you better say " already told in print" instead of " already told by Dudley Warner," as I prefer not to have Warner's name used.

I marked the letter to you " personal " so that you alone should see it, and the type written matter enclosed I marked " confidential " for the same reason. Please return this to me after you have copied what you have wished to use. The newspaper article about the Japs you may keep, as I have other copies.

Did you take with you the " Popular Science Monthly " containing Grinnell's article? If so, return it soon, as I have no other copy.

Your inquiry about my being a bachelor reminds me of another joke on me, which you might possibly find to use. A classmate once remarked about me - " It is strange that Marsh, considering all the bones he has found, has never got a rib."

My Dear Professor:--

Your letter of the fourth containing the biographical matter and the note in regard to the Bavarian pterodactyle is just at hand. I also received a letter a few days ago containing "Two Rescues" and the interesting little note relative to Mr. George Peabody's remark. All of these notes I am very glad indeed to get and I assure you that I appreciate your interest in the work. I have been devoting all my time recently to the preparation of the article and I hope soon to send you a copy of it. The interest in the subject has been growing upon me steadily and I feel confident that the article will awaken a great deal of attention all over this country.

What do you think of the April McClure's? We are rather proud of it; the first edition was 350,000 copies and that means a million or more of readers.

I have the *Popular Science Monthly* containing
