The common locust tree, 
Robinia Pseudacacia, blos- 
soms and produces large 
numbers of thin, flat pods, 
which remain of a dull color 
even when the seeds are ripe. 
The pods of the locust may 
wait and wait, holding fast 
for a long time, but nothing 
comes to eat them. They 
become dry and slowly split 
apart, each half of the pod 
usually carrying every other 
seed. Some of the pods 
with the seeds still attached 
are torn off by the wind and 
fall to the ground sooner or 
later, according to the force 
of the wind. Each half-pod 
as it comes off is slightly 
bent and twisted, and might 
be considered a “want- 
advertisement ” given to the 
wind : “ Here I am, thin, 
dry, light and elastic, twisted 
and bent already; give me 
seeds up the hill, into the 1 
bent, drift on the snow
