My dear Douglass:



Your very kind lines of June 7th in reply to my last letter came to hand during my absence at Amherst where I went to celebrate the firty-fifth Anniversary of my granduation in ath neat little institution.



I am going, just as soon as I can find the time, to get after Peterson and endeavor to discover your communications which you say you left in his care when you went west the last time.  I am quite sure that I shall wish to utilize some of them in my paper in which I shall give, as far as possible, a full account fo the operations at our famous quarry.

If the story is not soon written and published it will happen, as it has in other cases, that strangers will appropriate to themselves the credit of the work which you and I did together.
