acid, flavor poor, quality very inferior; seeds very large, averaging 
about 50 per fruit. The great number of seeds found in each fruit 
is distinctly detrimental to the commercial value of this strain. 
Table II shows the detailed performance record of a representa- 
tive tree of the Kough Seedy strain for the year 1912 and also the 
summarized record of the same tree for the 6-year period from 1910 
to 1915, inclusive. These records, in comparison with those from 
the tree of the Marsh strain presented in Table I, show the relatively 
small crops of trees of the Rough Seedy strain and the very high 
seed content of the fruits of that strain. The trees whose records 
are shown in Tables I and II grew near each other in the same plat. 
SMOOTH SEEDY STRAIN. 
The fruits of the Smooth Seedy strain, an illustration of which 
is shown in Plate VII, have a flattened shape, smooth texture, and 
ivory-white color of rind. Entire trees of this strain have been 
found, and individual fruits and limbs bearing several fruits of this 
strain are frequently found on trees of the Rough Seedy strain. 
These fruits are very similar in outward appearance to those of the 
Marsh strain, but they usually have about the same number of seeds 
as typical fruits of the Rough Seedy strain, and their characteristics 
of flesh and juice are similar to those of that strain. Such fruits are 
so nearly like those of the Marsh strain that it is frequently impossible 
to sort them out of the general crop, even by the most careful in- 
spection. For this reason, in orchards where trees of this Smooth 
Seedy strain are found it is especially important to top-work such 
trees, using select buds from the Marsh strain. 
ROUGH STRAIN. 
The production of trees of the rough strain is lower than that 
of trees of the Marsh strain, and the fruits are of inferior commercial 
quality. The habit of growth of the trees is usually erect, and the 
vigor of growth is greater than that of the trees of other strains 
of the variety. An abnormal number of branches of unusually 
vigorous growth, commonly called suckers, are produced b}" these 
trees. These branches usually grow very erect and are irregular in 
their habits of fruiting. The leaves are very large and usually 
somewhat sharply pointed and have large winged petioles. 
The fruits, an illustration of which is shown in Plate VIII, are 
globular in shape; size large; skin rough, coarse; color dull yellowish; 
rind about half an inch thick; rag abundant, bitter; juice scant, 
lacking in flavor and of inferior quality, and commercially seedless. 
The fruits of this strain usually ripen later than those of the Marsh 
strain, even when borne on different branches of the same tree.
