seeds of many pulpy fruits too hard to be chewed, or 
digested, as in the date and the peach? 
(4) Why are the seeds of some pulpy fruits too small 
to be easily chewed, and also indigestible, as in the fig 
and the currant? 
(5) Account for the not infrequent presence of currant 
bushes or asparagus plants in such localities as the forks 
of large trees, sometimes at a height of twenty, thirty, or 
more feet above the ground (Fig. 274). 
Careful observation of the neighborhood of peach, plum, 
cherry, or apple trees at the season when the fruit is ripe 
and again during the following spring, and an examina- 
tion into the distribution of wild 
apple or pear trees in pastures 
where they occur, will help the 
student who can make such ob- 
servations to answer the preced-

fruit-eating quadrupeds and of

when the fruits upon which they

done by Animals. — In the cases 
referred to in the preceding sec- 
tions, animals have been seen 
to act as unconscious or even unwilling seed-carriers. 
Sometimes, however, they carry off seeds with the plan 
of storing them for food. Ants drag away with them to
