          that Sprague cannot afford to make the 
 drawings for Emory at the price he made 
 those for Fremont $2. a piece. He will 
 do them better, having now such skill in 
 dissections he will display structure finely, 
 but he must not undertake them under
 $6. a piece, since they will cost him 
 as much time as do my 8vo [octavo] Genera drawings. 
 He might make what you want along this
 summer & autumn. I am not crowding him. 


 Well, I am glad you have got such a 
 good haul from Emory. I will aid you 
 as you desire about the Compositae, to which 
 you had better add the Scrophs [Scrophulariaceae], Polemoniaceae
 & Hydrophylls (tho' with all your 
 materials in my hands, I have not yet elaborated 
 that family) But do you want, just now, 
 the determinations & names, generally, or only notices of 
 the characteristic & peculiar ones? As to my being
 busy, I am afraid it will be much the same 
 thing the season through. For the text of the 
 Genera must be written and carried through 
 the press as soon as the Manual is done, & the 
 new Lindheimer plants must be studied & printed, 
 and a coll. [collection] is on the way from Santa F� to 
 St. Louis, etc. etc. My great object &
