understood, however, that the work is still in progress and later 

 results may modify the conclusions here given. 



Prune. — Prunes have not been on trial long enough to produce 

 fruit. However, the young trees are vigorous and appear to be well 

 adapted to the conditions, although this does not signify anything 

 of importance. The varieties on trial here are the Italian, Giant, 

 French, Epineuse, Tragedy, and Pond. 



Apricot. — The Cluster, Royal, Moorpark, Early Golden, and 

 Onderdonk apricots have been under trial since the spring of 1906. 

 Several favorable seasons have passed since these trees were of a 

 bearing age, but only a few fruits have yet been produced by any of 

 the varieties. To judge by its behavior, this fruit is not adapted to 

 San Antonio conditions, although a few seedling trees in the neighbor- 

 hood are said to produce fruit regularly but of rather poor quality. 

 Very often the apricot crop is ruined by frost because of its early 

 flowering season. 



Cherry. — The list of cherries that could possibly be of value under 

 San Antonio conditions is very small. From the behavior of those 

 tested and those observed elsewhere, the indications are that this 

 fruit is not adapted to this locality. The Advance, Eagle, Napoleon, 

 and a wild cherry from China were set out in the spring of 1911. The 

 Compass (not a cherry in the pomological sense, as it is a cross be- 

 tween the Miner plum and the Dwarf Rocky Mountain cherry) and the 

 Baldwin were set out in the following spring. 



Nectarine and plumcot. — Such other drupe fruits as the nectarines 

 and plumcots have been but little tested. The Crosby nectarine 

 set out in March, 1907, has borne only one crop of fruit since it began 

 to bear four years ago, and it behaves much the same as peaches of 

 the unadapted type. A seedling nectarine occurring in the Mexican 

 seedling orchard has made a vigorous tree, but has borne fruit spar- 

 ingly and has a tendency to very irregular ripening. This nectarine, 

 however, is of fair quality and may prove to be a good variety for 

 some other locality. Its behavior in the seedling orchard as a tree 

 and as to flowering and fruiting habits resembles closely that of the 

 peach varieties not adapted to this section. 



Apple. — Apples have been tested only in a small way at the station, 

 but the behavior of other near-by plantings in similar soils has been 

 observed. Very few trees have produced any fruit. Apparently this 

 region is not suited to apple production. Many apples fail to grow 

 into trees, remaining dwarfed and bushy. The only varieties observed 

 that have been partially successful are the earliest sorts. 



Citrus fruits. 1 — It is very doubtful whether even the hardy Satsuma 

 orange grown in parts of Texas will thrive as far north as San Antonio 



1 The testing of citrus fruits at this station has been carried on in cooperation with the Office of Crop Physi- 

 ology and Breeding Investigations, Bureau of Plant Industry.
