Dear Ellen,

It was a pleasure meeting you last week and I wanted to thank you again for taking the precious time to help arrange and make possible my rewarding visit to the Yale mineral reference collection. I was very pleased to see all the Tintic, Utah specimens you have, and I believe that your collection probably contains the largest number of preserved samples from this historic district that I have ever seen in one place. I am very satisfied with the valuable knowledge I acquired from my day at the Peabody Museum, and I certainly would like you to understand my appreciation and gratitude.

I am also returning the two specimens you kindly loaned to me for further analysis. I had each one of them run in a JEOL SEM with an EDAX chemical microanalyzer, and I tried to get away with using as little of the specimens as possible. Sample #MIN.3.3028 with the unknown pale green blades associated with carminite proved simply to be scorodite. And, Sample #MIN.1.5245 does not contain any nantokite, as labeled, and is instead connellite in various morphologies (fresh to pale blue corroded). Although I didn't find anything great, I strongly believe it was still worthwhile doing the testing anyway.

I went over to Bryn Mawr the next day following our meeting, and spent an enjoyable day there examining their Tintic specimens. Combined with quite a bit of driving across locally scenic countrysides and several meals at characteristic New York style diners, my trip was most pleasant and memorable. My thanks to you again, and I wish you success and relaxation in your upcoming (10 1/2 months) retirement.

Respectfully,

Martin Jensen
