TIMBER: FORESTRY

trees are finally to stand, or young seedlings may be procured 

 from a forest nursery. The latter plan is the better, and it is well 

 to have the young seedlings transplanted once or twice before 

 their final planting, to avoid formation of long roots, cutting 

 of which would check the growth of the tree. Both coniferous 

 and dicotyledonous trees are much planted. Some of the most 

 generally available conifers are several kinds of spruce, the 



Fig. 327. A four-year-old plantation of hardy catalpa 



At the left are Russian mulberry trees of the same age. Note the dense shade, 



sufficient to protect the forest floor from weeds. These trees were cultivated for 



three years, but now need no further care except pruning 



white pine, the Scotch pine, and the Austrian pine. Among the 

 desirable dicotyledons are cottonwood, silver or white maple, 

 green ash, honey locust, hardy catalpa (Fig. 327), red oak, and 

 (hi the warmer parts of the country) eucalyptus. In climates 

 such as that of the lowlands of California, Eucalyptus globulus 

 is the most rapid growing of hard woods, reaching a diameter 

 of one foot and a height of 125 feet in ten years. To reach 

 this diameter the white oak would take a hundred years.
