Dear friend, 
Your kindly sending me your excellent work about Yucca reminds me to send you 
a greeting again and at the same time to thank you for sending this to me. The 
Yucca shows somebody not close to it a really surprising number of species. 
I hope you will hear more from me soon. I was able to withdraw a little bit from 
the tremendous administrative work and was able to think again of something scien- 
tific. During the last months I was able to work on the Juncaceae of the Cap of 
which I have one of the best collections here, and hope to finish the work soon. 
I have used for these studies mostly Sander's Cape plants, in any event, one of 
the most complete colleetions in existence. 
But don't believe that I don't work on anything else. On the contrary, probably 
never before had I so much work to do in my office. My school has nOW 18 classes, 
beginning in autumn 19 classes and is expanding so that I decided already three 
years ago to divide it; now, finally, the work on the second building has started 
and after its completion, which will, however, probably take two years, I shall 
have more time for myself. 
At the present, we are much occupied with the coming International Agricultural 
Exhibition. The thing is going to take place on such a large scale that it will show 
us many more interesting things; also a congress of the German agricultural chemists 
is going to take place during those days. 
Unfortunately, I have not seen our friend Braun since last spring and am afraid 
he has become quite old. On the other hand, his works still have the stamp of his 
old mental freshness. I hope God will keep him for us for a long time to come! 
I ask you kindly to find out whether your Academy has received all our publica- 
tions (Transactions and supplements in 4 issues). Bya mistake, our secretapy did 
not enter it into the lists and it is, therefore, possible that you are lacking 
the issue® of the 3rd and 4th volume. Should this be the case, I shall fill your gaps. 
With best greetings to you and yours, 
Your devoted 
Buchenau 
Focke's Rubus studies made good progress and he will soon publish a row of works. 
Rust's country place is now almost finished. It really took a long time.
