UNIVERSITY OF CALIFORNIA EXPERIMENT STATION. 



feet high, with larger trunks. While much less attractive than the 

 columnar specimens, they are equally valuable for timber. 



The trees of a small block of Thuya gigantea (Port Orford cedar), not 

 tabulated, are about fifteen feet high, with branches that cover a circle 

 of 12 feet across, and, like those of the other conifers, are beginning to 

 interlock. All the older conifers showed in June, 1898, a spring and 

 early summer growth of 12 to 24 inches. 



The large deciduous trees on the station are growing quite as well as 

 the conifers. The following table shows some of the principal groups 

 and several specimens of especial usefulness: 



TABLE II. STATISTICS OF LARGE DECIDUOUS TREES. 



The birches noted in above table were received by mail in 1894, when 

 a few inches high, and placed in nursery. In January, 1895, they were 

 set out in a group adjoining the block of Sequoia. Their growth has 

 been marvelous, and justifies all that previous reports have said about 

 the value of Betida alba as a street tree. 



The Huntingdon elm has grown faster than the American and other 

 species tested here, and it also is a more shapely tree. 



The box elder grows rapidly, but it has little value and is less 

 attractive than the soft maples. Where much better trees will thrive, 

 it is a pity to plant box elder. The catalpa, with its showy flowers, is 

 far more attractive. The paulownia has little economic value here, 

 though its soft lumber has ornamental uses in Japan. 



Considering the quality of its product, the rapid growth of the ash 

 here is very suggestive. It thrives well on the various soils of the 

 station. Several species of ash are being tested, all giving promise of 

 usefulness.
