220 Macfarlane—The Beach Plum, Viewed 
reddish yellow, till a pure orange or gamboge yellow is 
reached, which in tint will compare with the finest cultivated 
plums of the Golden Esperon section. Some of the reddish 
yellow and yellow types are flecked with faint white specks or 
blotches, while others are quite uniform. The third line cul- 
minates in the finest blue-blacks. 
The surface variations thus shown, usually are an index to 
corresponding variations in color of the pulp. In the black- 
ish blues, this is of a dull reddish purple hue; in the bluish 
purples of a pale greenish red; in the purplish greens of a 
light watery green, while in the red-yellow series it passes 
from shades of pale watery red to watery yellow. 
The color variations of the stones follow those of the fruits 
though to a less marked degree. The stones of black-blue 
fruits are of a purplish red hue when fresh, changing to dull 
red when dried. Those of the purplish-red fruits are of a 
faint red or reddish yellow hue; of the red fruits the stones 
are faint yellow. Finally, the yellow fruits have clean whitish 
yellow stones. 
(0) Frut-Weight.— Under this head it is possible to 
introduce exact statistics, and in the subjoined table some of 
these are grouped, as drawn from study of twelve distinct 
varieties. The bracketing of these under five groups has 
reference, more or less, to the color relations already discussed, 
and it will be seen that one of the first group (No. 7) ofa bluish 
black hue, excels in every detail. The types that are poorest 
in flesh, and have relatively the heaviest stones are those 
already alluded to, as of a purplish green color, and which 
suggest the possession of primitive characters in every respect. 
Number 12 of the table is a remarkable variety, represented 
only by three bushes at Cape May Point, that are widely 
apart from each other. They agreed in being slender bushes, 
about three and one-half to four feet high, that produced fine 
twigs clothed with small leaves. The fruits were of small
