          Cambridge Tuesday Eveng. [Evening]


 My Dear Friend, 


 Your favor of yesterday morning 
 reached me this afternoon. The new P.O. [Post Office] law is
 an excellent thing, as it enables us to exchange our
 missives frequently, to send little pieces of news and 
 ask and answer questions without waiting for 
 time and matter to fill up a formal letter. 


 I must tell you of a little change made in 
 my sanctum here. You are to imagine me 
 writing at a sort of Bureau-escritoire standing under
 R. Br.'s [Robert Brown's] picture, which I fortunately picked up the 
 other day for $10. It is of fine old dark wood 
 a century old, and contains below four drawers,
 while the upper part, which opens into a fine 
 writing table, has 8 pigeon holes, 6 drawers, and 
 a little special lock up with several drawers &
 pigeon holes more. You know I like any quantity of 
 these stow-away places. I have sent up stairs the 
 table which stood in its place, and brought down 
 the round one in its place, so that have more 
 room than before. 


 I have been distributing the Monopetalae into their 
 places in the herb. [herbarium] preparing for gluing and finishing off 
 the Linheimer Coll. [Collection] as well as assisting the Texan plants 
 from Wright. I have also to-day put things in 
 order for a renewed attack on the Ericacea. I shall 
 finish the others, and then turn back upon Vaccinium,
 the hardest of all. Some time when you are sending.
