PLANS FOR MUNICH. 45 



Carlsruhe. Remind me then to tell you about 

 the theory of the root and poles in plants. 

 As soon as I have your answer we will be- 

 speak our lodgings from Dollinger, who will 

 attend to that for us. Shall we again house 

 together in one room, or shall we have sepa- 

 rate cells in one comb, namely, under the same 

 roof ? The latter has its advantages for grass- 

 gatherers and stone-cutters like ourselves. . . . 

 Hammer away industriously at all sorts of 

 rocks. I have collected at Auerbach, Wein- 

 heim, Wiesloch, etc. But before all else, ob- 

 serve carefully and often the wonderful struc- 

 ture of plants, those lovely children of the 

 earth and sky. Ponder them with child-like 

 mind, for children marvel at the phenomena 

 of nature, while grown people often think 

 themselves too wise to wonder, and yet they 

 know little more than the children. But the 

 thoughtful student recognizes the truth of the 

 child's feeling, and with his knowledge of 

 nature his wonder does but grow more and 

 more.
