mental have been made of those extending below the conif- 

 erous timber belt. 



Chief among them, the Oregon ash, Oregon maple, syca- 

 more, cotton-wood, and laurel occur mostly in cafions, and 

 with the exceptions noted are unsuitable for general planting. 



The cotton-wood, Populus Fremontii, has shown (on a large 

 scale) conformability to the lands strongly alkaline. Such are 

 waste lands for this purpose, as the process of reclamation is 

 tedious and costly. They comprise many thousands of acres 

 of our West Coast bottoms, and no tree outside of this cotton- 

 wood and Tamarix gallica (exotic) that has been tested upon 

 them has heretofore proven satisfactory. Growth quick ; timber 

 warps badly ; rates low for fuel. 



The Laurel, Umbellularia Galifornica, has been attempted 

 away from water-courses, with some measure of success. The 

 timber is invaluable for veneers, exceedingly hard and heavy, 

 and excels the cherry and redwood burl in beauty, but is of 

 such exceedingly slow growth that few attempts have been 

 made looking to its extended planting. 



PART III. 

 (B) Exotic Species. 



Considerable plantations have been made throughout the 

 State with Eucalyptus species. 



These in size range from one to four hundred acres. Plan- 

 tations have been made with some fifty species, but ninety per 

 cent, embrace, 



No. 1, Eucalyptus globulus. 



Nine per cent, are of 



No. 2, Eucalyptus rostrata, and
