 My Dear Friend 


 Your welcome enclosure of 
 the 26th 28th etc. came this morning 
 and I will scratch off a few lines 
 immediately.


 The zygophyllaceous plant was 
 not left for Sprague to draw. He 
 shall draw it, any [and] anything else you 
 desire, but as he had full occupation
 all summer, and in fact has fallen 
 behind with needful work, it was not 
 worth while for him to exert himself 
 for those things when they would not be 
 wanted till late in the winter. Meanwhile 
 Sprague has learned very much, understands
 structure pretty well, dissects
 with wonderful aptness, and if you could 
 see some of the drawings I have just 
 forwarded to Prestele, you would be as 
 much pleased with his progress as I am. 
 Send on what you wish drawn, and
