 estry station at Santa Monica, and determinations of the tannin con- 

 tent of the bark and the results of practical tanning tests; meteorolog- 

 ical observations; a statement concerning the amount and kind of 

 seeds and plants distributed by the station since 1886, with reports 

 on the growth and value of roselle, fenugreek, saltbushes, and other 

 plants included in the distribution; lists of donations to the university 

 botanic garden; notes on plants received for identification; and detailed

GENERAL OUTLOOK. 



During the year the California Station has published the results of 

 investigations with olives and other fruits, grape must, phylloxera, 

 soils of the arid region, alkali in irrigated soils, tobacco, legumes, and 

 forest trees. The diversified productions of California necessitate a 

 wide range of investigations, and hence the attempt has been made to 

 study problems more or less local in nature at the substations. Thus, 

 for twelve years the substation near Paso Robles has been made the 

 center of observations relating to the deciduous fruit interests over an 

 extensive region; the substation near Jackson has investigated the 

 fertilizer needs of that region, using with success vetches and European 

 lupines, and has successfully grown olives for oil, besides starting a 

 plantation of Smyrna and Capri figs; and the substation near Pomona 

 has been the center of a wide range of studies on citrus fruits, particu- 

 larly the orange. The general success of the station's operations has 

 led to a popular demand for more work than the station has funds to 

 support. To carry on thoroughly satisfactory- investigations for so 

 large an agricultural region as is found in the State of California, the 

 station needs larger financial resources, and with the increased resources 

 of the college of agriculture of the university, it is hoped that it may 

 be possible to extend the operations of the station. The number of 

 outlying substations should either be reduced or more ample provision 

 should be made for their maintenance under conditions which will 

 bring their work into more direct relation with the operations of the 

 central station.
