EUCALYPTUS. u 9 



tall, erect and regular. The variations in the bark of 

 eucalyptus trees, classified as belonging to the same species, 

 has been attributed to diverse geologic or climatic condi- 

 tions. At Berkeley we see the Eucalyptus viminalis on the 

 same soil showing on the one hand a rough, dark persis- 

 tent bark, and on the other a smooth, white decorticating 

 one. 



I was struck at Berkeley by the great number of Mon- 

 terey Cypress seedlings coming up in the grounds. We see 

 oaks, Eucalyptus and acacia seedlings often enough in Cali- 

 fornia, but those of Cupressus macrocarpa are almost un- 

 known except in a nursery. 



The handsomest exotic trees I saw at Berkeley were, I 

 believe, specimens of the black wattle, acacia decurrens. 

 The feather<' foliage in dense masses on these giant trees 

 was both charming and impressive. The rich, heavy soils 

 of Berkeley are evidently to this tree's liking. There are 

 good specimens of the rough persistent and smooth decor- 

 ticating barked varieties of Eucalyptus amygdalina on the 

 Campus, otherwise the Eucalyptus plantations at the Uni- 

 versity grounds are uninteresting.
