BLUEBERRY OR HUCKLEBERRY—BRAZIL NUT—BREAD FRUIT 
of the delicate nature of the young plants 
and the very careful treatment which 
they require The same station made an 
examination of the flowers of this species 
in order to learn at what time the stamens 
yield their pollen. 
This seems to be given off immediately 
before and for a short time after the corol- 
la opens By opening the corolla of flow- 
ers about to expand and jarring the blos- 
soms vigorously over a glass slide, we se- 
cured pollen in considerable quantities, 
which is an indication that the flowers 
may be at least in part self-fertilized 
Nothing appeared in the structure of the 
flowers to render artificial crossing dif- 
ficult. 
The experience of one grower in Massa- 
chusetts leads him to the following con- 
clusions: 
(1) It [the high-bush blueberry] does 
not take kindly to garden cultivation; (2) 
it is very difficult to propagate from the 
seed; (3) it is somewhat difficult to graft, 
but patience and a little of the “know 
how” will overcome all of these. If grown 
in the garden, (1) they must be on the 
north side of a board fence or in the 
shade of trees and the ground must be 
mulched with leaves or evergreen boughs; 
(2) let the seed get fully ripe and drop, 
then sow in a shady place; (3) graft 
small bushes at the surface of the ground 
and cover most of the scion with moist 
earth. 
Success in growing blueberries has been 
attained by all of these methods. 
Another grower reports that he has 
been very successful in growing high-bush 
blueberries on a poor, rocky, upland soil. 
The bushes improved much in thrift and 
yielded from three to four times as much 
fruit as wild bushes growing in pastures 
and swamps and the berries were from 
25 to 30 per cent larger. He advises set- 
ting plants 6 feet apart each way and 
mulching with strawy manure in the fall. 
The results of the experiments thus far 
conducted would seem to show that the 
blueberry is subject to much variation and 
is greatly improved by cultivation. Blue- 
berries are as yet but little cultivated, 
but the few attempts that have been made 
661 
toward their improvement indicate that 
with care satisfactory results may be ob- 
tained. Meanwhile natural blueberry bar- 
rens may be made to give increased yields 
by systematic burning and care, and thus 
these lands, otherwise worthless for agri- 
culture, made sources of profit.

Brazil Nut 
The seeds of a Brazilian tree, called also 
Castanea, Cream nut, Nigger toe, Para 
nut. It belongs to the natural order 
Myrtaceae, species Bertholletia exceisa, 
The tree often attains a height of 150 feet, 
and a diameter of four feet. It has bright 
green, leathery leaves, two feet or more in 
length, and six inches in width. It bears 
cream colored flowers and a very hard 
shelled fruit six inches or more in diam- 
eter, containing about 20 three sided 
wrinkled seeds, which are used for des- 
sert, confectionery, and for the manufae- 
ture of an expressed oil used in oil paint- 
ing, lubricating fine machinery, and in 
lighting. This tree covers large tracts of 
land in Northern Brazil, along the Ama- 
zon and Orinoco rivers.

Bread Fruit 
Artocarpus incisa 
A tree of the natural order Urticaceae, 
native of the Indian archipelago and of 
the Southern Pacific islands. It attains 
a height of 30 or 40 feet; is often limbless 
for half its height, bears leathery, glossy 
dark green, three to nine-lobed leaves, one 
to three feet long; has compact club- 
shaped, yellow catkins of male flowers, 9 
to 15 inches long, and sub-globular heads 
of female flowers, with spongy recep- 
tacles; and usually seedless, spheroidal 
fruits, at first green, later brown, and 
lastly yellow, six inches or more in diam- 
eter, hanging by thick stalks singly or
