Dixon, Wyoming Sunday June, 10, 1923 Douglas Stewart Carnegie Museum Pittsburg, Pa. Dear Stewart:- Our second car is in but it was loaded with automobiles which were to be unloaded to day. We came up north of Craig to collect some fossil plants which I had found in another locality and horizon. We made collections -- (probably it is lower Tertiary) -- and came north to explore farther and concluded we would come on to Dixon to "sketch" the country. It is all Tertiary here.
