ng only one of the best growing pumpkins. See
whether this one grows larger than one of equal age on a vine having
young pumpkins developing on it. Notice the arrangement of the seeds
inside a ripe pumpkin. Collect some seeds, wash clean, and dry for
spring planting. It is desirable to plant pumpkins late in May, so that
they will have flowers on their vines as late as September.
Study the flowers of the cucumber and compare them with those of the
pumpkin.
CORN
This plant is native to America, was greatly prized by the aborigines,
and even worshipped by some of them. Note the upright character of the
plant and how the stalk is divided into sections by the joints, or
nodes. Count these joints and also the leaves, and note the relationship
of leaves and joints in the stalk, and how the leaves come off in
different directions so as not to shade each other. Note the strong,
stringy threads in the leaf, which give strength to the leaf as well as
circulation of sap. They are strong and elastic, allowing of movement.
The same strengthening fibres are seen in the stalk when it is broken
across. In the stalk these fibres are arranged in a tubular form, as
this gives greatest strength, the centre being soft and weak. The stalks
are largest near the base, where the greatest stiffness is required. The
nodes are also closer together here for strength. The stem is made much
stronger by the bases of the leaves being wrapped so firmly around for a
distance above the point of attachment at the node. Notice the
close-fitting sheath or rain-guard, where the blade of the leaf leaves
the stalk. This prevents rain soaking down inside the leaf sheath, but
lets it run down the outside to the root where it is needed. As the
plant gets older and taller, new roots come out from the node next above
the root and sometimes from the second node above. These prop-roots are
needed for support as the stalk lengthens, and they also reinforce the
feeding capacity.
Note the appearance of little cobs in the axils of the leaves. As soon
as the silk appears, take a cob off and open it carefully. The little
cob, which corresponds to the pistil in other plants, is covered with
small and undeveloped kernels, and to each kernel one of the strands of
so-called silk is attached. Whilst this little cob is forming, a bunch,
or tassel, of flowers is forming on the top of the corn plant. Open one
of these flowers and find the stamens with pollen-grains inside.
