that avocados in our northern and eastern markets during the summer 

 months, even at this stage in the development of the industry, sell at 

 the low figure of ten cents a fruit. 



Even within the Trapp variety we find a similar variation to that 

 existing in our citrus varieties. I have found at least five distinct 

 strains in this variety, which are characterized by differences in produc- 

 tion, differences in foliage, and differences in the flower arrangements. 

 Correlated with these differences are distinct variations in the shape of 

 the fruit, some being pyriform, others oval, and others distinctly oblate. 



The accompanying chart (table 1) shows the wide range of varia- 

 tion in production which exists in a young planting of Trapps in which 

 we are securing detailed individual tree records.

Fruit was picked from this planting as follows: 

 Oct. 1 — 8 crates No. 1. 

 Oct. 2—2 crates No. 2. 

 Oct. 29—6 crates No. 1. 

 Oct. 29—3 crates No. 2. 



A considerable number of fruit, aggregating probably 3 or 4 crates, 

 dropped after maturing. These are included in the list for each tree, but 

 are not included in the quantity picked. 



In this same orchard this year we have found that the high pro- 

 ducing trees in 1915 are also the high producing ones this year, while 

 many of the zero trees are also repeating. 



Turning for a few minutes from avocados to citrus, you are all 

 familiar with the action which has been taken by the California Grape- 

 fruit Club, an auxiliary of the California Fruit Growers Erchange. 

 Repeated trials of different grapefruit varieties in this state have 

 shown that only one variety, the Marsh, is suited to conditions here. 

 Even in the Marsh variety a number of inferior strains are found. The 

 California Grapefruit Club has officially agreed that its members will 

 rebud all varieties other than the Marsh and all inferior strains of the 

 Marsh to the smooth thin-skinned ideal strain of this variety. You can
