EXPERIMENT STATTON RECORD. 



P. sylvestris. Both blocks were set in 1889-90. The P. resinosa trees 

 average 17 ft. in height and the Scotch pine about 13 ft. 



Observations were made by an inspector of the young trees in the 

 Sierra showing that seedling pines and other conifers wherever pro- 

 tected from sheep and cattle form close thickets in a few years. During 

 the winter of 1895-9(i, which was a very severe one, quite a number of 

 Eucalyptus and Acacia trees were destroyed, as well as a number of 

 carob trees. The heat of the following summer destroyed quite a num- 

 ber of trees, among which were specimens of Abies, Sassafras, and 

 Gephalotaxus drupacea. The Japanese oaks have also proved unadapted 

 to this region. The rate of growth of trees in the forest is shown in a 

 table compiled from records made by the foreman of the station. The 

 growth of 9 specimens of conifers and 4 deciduous trees are tabulated as 

 follows :

A list of trees and number of species being tested at the station is 

 given. The general condition of the Santa Monica station is described 

 and temperature and rainfall records for the years 1893-1897 are 

 included, together with descriptive notes and improvements. 



Measurements have been made of the larger Eucalyptus trees in the 

 main grove and the results were tabulated, showing the growth of the 

 trees for the years 1894, 1895, and 1890. The trees were mostly planted 

 in 1889 and 1890, and in many cases have attained very considerable 

 size. One specimen of Eucalyptus globulus was measured in 1896, being 

 reported as 40 ft. high and 19 in. in diameter, with a spread of top of 

 28 ft. 



The flowering time of the various species of Eucalyptus are given, 

 the lengths of their blooming period, and their possible use as bee 

 pasturage. A table is given in which the comparative resistance of 

 several of the more common species of Eucalyptus is shown. The 

 figures given seem to indicate that Eucalyptus globulus and E. coryno- 

 calyx are among the most resistant. Brief descriptive notes are given 

 of some recent additions to the arboretum, among which are some 

 Japanese bamboos, Mortis multicaulis, various willows, etc.
