          Washington City, February 21. 1849.


 My dear Sir,


 I have been so continuously 
 out of health since the beginning of the year 
 that your letter and the list have had to 
 lie by until now. My eyes being somewhat
 affected by general weakness I would not use 
 them. Long hopeful letters from Mr. Frémont 
 and the knowledge of his being in safety up to
 the 1st of December have had their share in 
 making me feel better, and although I leave 
 now in a fortnight I shall send you the 
 finished list. 


 I think the drawings 
 made on the last expedition must have been 
 carried along to be put with those now being 
 made. I cannot find the one you speak of. Mr. 
 Frémont shewed it to me & I remember it well. 
 If you have a proof can you let me have one 
 to take to Mr. Frémont? I shall be in New York
