EUCAL YPTCS. 23 



for cold places, and on the blue gums' limit of tempera- 

 ture it is better for all sandy places and especially better 

 for beaches exposed to sea winds. The Monterey pine, 

 however, is not a valuable timber tree nor a good fuel 

 one. Its uses are to hide scars, cover waste places, stop 

 sand drift and look as handsome as a young pine can. It 

 stands cutting and breaking better than any pine with 

 which I am familiar. I know of one case where it 

 sprouted from a blown over tree and grew well. The 

 main tree was not cut off until the sprout had started. 



Mr. L- Stengel, an experienced and careful nurseryman, 

 is of opinion that Eucalyptus has a strong tendency to 

 hybridize. There is just now a demand for Eucalyptus 

 robusta (swamp mahogany). In preparing for this Mr. 

 Stengel gathered robusta seed from four handsome spec- 

 imens on Downey avenue, East Los Angeles. Recently 

 while visiting his nursery Mr. Stengel showed me the 

 results of his seed planting. The vast majority were true 

 to the parent tree, but many in his large planting varied 

 very widely from Eucalyptus robusta. One specimen was 

 identical with globulus, several were like amygdalina var- 

 regnans; in fact about fifteen distinct species apparently 

 came from these robusta seed. If hybridization be accepted 

 as the cause of these nursery results, we may account for 

 some of the truly extraordinary surprises Australian Euca- 

 lyptus seeds have given us. I have personally known seed 

 from the collection of Baron von Mueller, and forwarded 

 most kindly by him, come up in form quite foreign to the 

 tree as described by him. I believe that every Californian 

 experimenter in Eucalyptus has had a similar experience 

 with Eucalyptus seeds.
