And even if nothing carae of the missioir to Paris, a nice piece of my 

 project would have beenr advanced~, and, at least, I can send you 

 something decent" and write aboixt it.. Over time I may have made thou- 

 sands of preparations, which' I peruse every free half hourr, but I do 

 not have the continuous time to properly examine the preparations 

 and to compare them. This Summer is the first, which I will devote 

 entirely to that labour,and, hopefully, we will soon be in the clear 

 with matters, which 1 wer e still dubious.. 



Since a year I have also much piddled in other f amilies-, spe- 

 cially ; Oaks, ? t willows, birches. I, now, acceptecf an entirely new 

 system of collecting and cultiimting?, and become through this aware 

 of an entirely new world. . The impetus was this: Professor of botany 

 at the Forest Academy of Munden in Hanover', Dr. Muller,, asked me to 

 help with trial cultures of seeds of forest trees-from differentt 

 altitud.es above sea-leveli, soils, etc. and sent to me for this prin- 

 ted sacks, of which I send one to you for^viewi!^/' Muller is after- 

 physioloerical stories, but I saw soon, that there is more to be had 

 by a 



svstematic approach. I arranged for collecting b;y pnpils and 



aquaintances in Poland, Hu.n^ary,Krain , Tyrol , Bohemia, and found,,that 



in the same soil and the same habitat the^e are quite different tv. 

 pines firs-,Stiel Eichen (Quercus robur) »Traubem Eichen (Quercus 



petrea) . Düring the present Winter I r received 300 specimens of 



spruce,, fir&, pines,Krumholz( <$«««ew-mugo, E. D. ) ,Kirbe (do not 



know, B.D» •) .Larch, . Carpinus , ,0 strya , Fagus , Stiel Eiche ( Quercus 



robur , E. D. ) , Trauben Eiche ( Quercus petrea , E. D.O,. Corr-oak,, ash„ 



Gormas , Birch,, Black-, White- and Green Alder,Linden f Maples. . 



1 serrc zo wunden always about of the shipments and kept 1/10 



for the collection of seeds and cones'; of this I sowed a small 1 part' 

 as I do not have much extra space.
