Walter’s current project is figuring out the etiology of endemic typhus (Rickettsia typhi). He suspects – correctly, it turns out – that rat mites are vectoring the pathogen.

Thursday PM.

My dear Sweetheart,

Your letter and the pictures came this noon. The pictures are very good and I am mighty glad to see them. Will keep them for the Baby Book. Walter White seems to be holding his own with so many new people.

May 15, 1930

I am enclosing a letter which was received from Mother today. Uncle Henry lost the little boy we saw at Sibley, La. I’ll write to him and to Mother tonight.

Yesterday Dr. Bedford brought his addition to the manuscript. It is very good for a rough draft but there is some duplication of information. This noon I had lunch with him at the Athletic Club. We plan to go to Longview and nearby places next Thursday PM. They have had quite a few cases of typhus. We want to determine whether or not rat mites are present. He wants to test samples of blood for typhus reactions (Weil-Felix test).

Mr. Somnier painted the gables of the house and the front of the garage. Today he is mowing the lawn and cutting the weeds in the back yard. The place is changing quite a bit. Perhaps this will be an added inducement to get the Mrs. to return to her husband.

With all my love, I am

Your Walter.
