How Seeds Grow.
In the seed, The parent plant stores away
sufficient quantity Of nutritious matter 70
support the young plant until Il can send
down roots into the ground and support it.
solL Plants know well enough that the
young germs BY which their species are
proplgaled cannot take care Of themselves
until they have rooted IN the soil and ex,
panded few leaves In the air; so they store
up in little sack around them ample pro.

wheat Iegumen in peas and beans, etc. II

long Is the grain e kept dry, no change oc.
cufs losnhlure has 90 arranged Il that
change can be effected only by moisture. If
Il were otherwise Il would Be impossible 10
preserve grains, for as soon Is matured the
kernels would sprout and grow.
Moisture and darkness, with suitable
warmth, are The necessary conditions for
termination, and at The freezing point all
VogclafiVo processes come 70 . standstill.
All these are furnished BY the sunwarmihed
earth. A soon as the seed is dropped into
