Nature. after ALL is the great contriver. Wit
oil tho material thoro is. with all the time thor
has been. sho has made 1t her task to find on
how everything that lives can come to its bes
estate. and do its work In the easiest way. A
rain falling upon mountain peak asks n
Cuideposts to show 1t the shortest path to tn
valley. so the rootlets Of n flower mood no gar
dener to bid them thicken and multiply alon,
tholine where they find most food On the arl,
plains Of Arizona a vine. in burrowng down

successfully. Finding It's sustepance neat

Every wind that stirs those roots but promote,

In seeking it. tho roots throw to tho surface
tho "knoes." whose effect in bracing tho trec

In the tra nsmission Of life from the stem OF
plant to its seed, n thousand influences IRE
conveyed. Little wonder that their delicate
poise should be unsteady. that certain of the
now shrubs Or troos should be n little different
from their parent Perhaps this parent il u
cactus and one of Its Offspring has u ieshier
stem and less surface than any other member
OF the family In dry soil and parching at
mosrhere this will be tho plant to get the best,
foothold nnd maintain 1t with most vigor. And,
the very competition which means death to
Its weaker rivals assures this bettered
stock chance to multiply Its kind.
