UNIVERSITY OF CALIFORNIA EXPERIMENT STATION. 



A large number of selected trees were shipped in the spring of 1897 to 

 various points north of Chico, also to a number of points in the San Joa- 

 quin Valley and in Southern California, so as to afford comparative 

 tests of species on different soils and at different 'elevations. 



Nursery in 18989. So many shipments have been made, and so 

 many trees planted out, that the nursery stock is greatly reduced, but it 

 contains some fine conifers such as Cupressus Corneyana and C. Lusi- 

 tanica, also some broad-leaved evergreens, principally from Chile, the 

 Southern States, and Japan; also, some new willows, many useful 

 deciduous trees, and ten or twelve species of economic and flowering 

 shrubs, for which a separate place has been selected near the west 

 entrance. Magnolia glauca is doing very well. Persea Lingue and Boldea 

 fragrans also seem well adapted to the place. 



Self-sown Seedlings. An interesting feature of the station is the 

 extent to which forest trees and other seedlings are now growing in 

 various parts of the grounds. In May, 1898, the following species were 

 observed, in great numbers, from self-sown seed of the previous autumn: 

 Juglans Californica, Catalpa speciosa, Paulownia imperialis, Negundo 

 California, Fraxinus Oregana, Cercis Texensis, and Vitis Calif ornicaj 

 besides sycamores, cottonwoods, and willows. A few Cupressus semper- 

 virens and Pinus Austriaca have grown from self-sown seeds in the groves 

 of these species. 



STUDIES OF TREE DEVELOPMENT. 



The especial fitness of the soil and climate of the region to the pro- 

 duction of timber and to the growth of a very great number of species 

 of trees, is shown by the following notes of measurements made at the 

 forestry station. In each case, typical trees have been chosen for the 

 measurement, and marked. Where wide variations occur, several trees 

 are measured. The blocks are remarkably uniform in size of trees, 

 and now so cover the ground that cultivation has properly ceased. 

 Except in the case of the Araucaria, the trees represent close-planted 



groups :

The age of all these trees is about the same. They were planted in 

 1888 or 1889, but no record was kept by the persons at the station 

 before the forestry work was given to the State University. Cultivation
