immature state, in order to secure a fruit with firm flesh. These vari- 
eties, especially the Sevillano, are inferior in flavor, due probably to 
the lack of oil as pickled, but bring a large price on account of their 
extraordinary size. When pickled by the California method, they 
may be said to differ from a green pickled olive in that they are black 
and do not have the 
piquant flavor of the 
green pickle. Con- 
sidering these facts, 
it seems impractica- 
ble to attempt to set 
any maturity stand- 
ard for these olives. 
Properly speaking, 
the Nevadillo olive, 
one grove of which is 
represented in figure

As a matter of interest and for comparison with the data just 
given, a number of averages for olive varieties, without reference 
to maturity, are given in Table 4.

RESULTS OF EXAMINATION OF PICKLED OLIVES. 
In 1914, and again in 1916, arrangements were made with a number 
of picklers for the sampling of marked vats of olives, as received, 
or before pickling began, and at the end of the process. Much 
practical information was gathered during this work, in which the 
picklers, with one exception, cooperated cordially. The data from
