          Sprague has been somewhat interrupted, by the 
 sickness of Madam, and is likely to be hard
 pressed through. He has got at least 
 five weeks of hard work before him. 


 I have my four last (geographical) 
 lectures arranged quite to my mind, if only 
 Sprague gets the illustrations done. 


 As to Fremont's drawings. I think the 
 Scotch gardener would be spending his valuable 
 time to much more purpose in collecting &
 making specimens. 


 I have twice met Lieut. Davis since 
 his return from Washington, but only just so
 as to have a passing word with him. He will 
 not go to Oregon. But he says a 
 friend of his is to be sent on that or some 
 other expedition. I suspect some other, as 
 he spoke of Black feet Indians, a naturalist 
 is wanted, and he says he hopes I 
 will have a man ready. Who can be 
 sent? I shall learn the particulars 
 as soon as I get time for a little talk with 
 him.
