Facts About the Seed.

cane in the world beets might be
cultivated to take it's place entirely,
but If there were no longer any po-
tatoes, the domestic economy of thou
sands of humble homes would be seri-
| ously deranged, and the depriva ton
would be considerable even on the
most luxurious table. That the sugar
cane and the potato are in danger of
/ becoming degenerate and finally ex-
tinct has for some time been recog-
nized in botanical laboratories all over
the world. In this country the botani-
cal department of Harvard university
has gone into the matter with good
deal of thoroughness, and expert
ments have been undertaken to per-
petuate these valuable species, says
the Cincinnati Enquirer.
The danger lies in the fact that both
have been propagated for so many
generations from buds-the sugar
cane from the joints of stalk, and the
potato from the eyes of the tuber-
that they have almost lost the power
of producing fruitful seeds. For a

~ continued, the fact that the seeds
themselves become sterile or dwindle
away and disappear, does not seem
particularly important Finally. how
ever, there comes a time, like the
present, when whole species shows
signs of the deterioration which pre-
- l.,
by crossing one plant with another
plant, or one variety with another va
riety, that the life of the species can
be renewed. But if the plant has lost
its seed-producing faculty, such cross
ing is evidently impossible, and the
degeneration must continue to it's
logical result.
Sugar cane is, of course, one of the
most valuable and important of agri-
cultural products. 1t IS at present
grown in all warm countries, and the
plants for so or 100 plant generations
have been started from the buds
which spring from the joints of the
cane. A section of the stalk contain
ing one of these generative joints is
planted and a new stalk or group
springs up, the plantation being thus
maintained by portion of it's prod
ucts. Meanwhile, as the plants ma
ture, they put forth blossoms, which,
though as beautiful as they ever were,
perhaps, are meaningless and unfruit-
full. When it was discovered by the
botanists that the sugar cane was los
ing its power to produce fruitful seeds,
1t was realized that such loss meant
linbreeding, as it would be called in the
case of animals, and that, unless some
artificial means of restoration could
be employed, the species would
eventually run out
The potato is among the cheapest
of all the cultivated foods, and while
| it is generally known that it is re-
produced by budding, pieces of the
tuber containing eyes" being plant
ed in the ground. most readers will
be surprised to learn that potato seed
is an almost unheard-of curiosity. In
the museum of economic botany at
Harvard there are models of potato
plants including the pink and white
blossoms and the grape-like fruit, but
this seed-containing fruit has become
so nearly extinct that few people, even
from the agricultural districts of the
country, have ever seen it. In the
models, however, it is clearly shown
that the potato is closely related to
the tomato. and the two-celled ar
