0E8KUVA'I'K)N« OJN olive" VAlilKTIKS, W. (i. Kn-IE. — The IblloW- 



iug brief introduction is by Director Hilgjird: 



T)>c iucrccising i)romiiionco of olivo culture in this State gives importance to all 

 light that can be thrown upon the snbject, the more as the slow growth of the tree 

 rondors mistakes made in the selection of varieties both»costly and difficult of recti- 

 lication. It is therefore the intention of the st.-ition to subject both the growing trees 

 and tlio fruit and its i)roducts to the n)o.st thorough comparative observation and in- 

 vestigation, as (juickly as the material shall be obtainable. In the meantime, the 

 observations of Mr. Kleo !i|ipear of sufficient practical im[ior(-anc<! to justify their 

 pul)lication at this time. 



It is evident that both with respect to the production of oil and that of pickled 

 olives, the proportion of kernel to meat is amatter of no mean importance, when wo 

 see, as is shown below, that this proportion varies all the way from 8 to over 34 per 

 cent. Some have the impression that the oil of the kernel or pit forma a consider- 

 able proportion of the product, but the investigation of this point made bj^ Mr. L. 

 Paparelli upon the common olive of Central Italy, showed this proportion to be as 

 one to thirty, while in the Mission olive, noted for the rarity of sound kernels, the 

 ju'oportion was found by Mr. Ad. Somnier, of the University, as one to one hundred 

 and sixty-two. Hence to the oil maker, as well as to the consumer of pickled fruit, 

 the data given will be of some interest. 



The accouut of the observations made by Mr. Klee relates to the 

 growth of a number of varieties of olives during- several years. 



This is, of course, only the beginning of observations w^hich will be continued for 

 years to come. Nearly all the varieties enumerated are now growing at the four dif- 

 ferent experiment stations, viz., Berkeley, Taso Robles, Jackson, and Tulare. Those 

 at lierkoley were planted five years ago, while those at the other stations were set 

 out only a year ago, and thus afford but few data of value. Observations of the 

 varieties growing on the grounds of the California Nursery Company, Niles, and at 

 Fancher Creek Nursery, Fresno, were also made through the courtesy of their re- 

 spective managers. 



The tabular record includes data for sixteen varieties, on the name, 

 age at planting, whether cuttings or grafts, diameter of stem or crown, 

 height, and habit of growth and bearing, at Berkeley and elsewhere. 

 Xotes of measurements of fruit, etc., are also given for thirteen varieties 

 and notes on growth and general behavior for eleven varieties.

Experiments with tobacco. — 



Introduction, G. L. Ingersoll, M. S. (pp. 3, 4). — In 1884 a small amount 

 of good tobacco was raised at the college, and in 1888 and 1889 larger 

 experiments with this plant were conducted at the station. "The results 

 of the two years' work are recorded brielly in this bulletin. The chem- 

 ical analysis of the several varieties raised is also tabulated for com- 

 parison and reference, and shows a quality that is good from the chem- 

 ical standpoint." The director believes that through these experiments 

 another money-making crop will be added to the agriculture of the
