[Illustration: FIG. 5.--Germination of Morning Glory, _a_, caulicle; _b_,
cotyledons; _c_, plumule; _d_, roots.]

[Illustration: FIG. 6.--Germination of Sunflower.]

After drawing the Morning-Glory series, let them draw the Sunflower or
Squash in the same way, then the Bean, and finally the Pea. Let them write
answers to the following questions:

MORNING-GLORY.[1]

[Footnote 1: It has been objected that the Morning-Glory seed is too small
to begin upon. If the teacher prefer, he may begin with the Squash, Bean,
and Pea. The questions will require but little alteration, and he can take
up the Morning-Glory later.]

Tell the parts of the Morning-Glory seed.

What part grows first?

What becomes of the seed-covering?

What appears between the first pair of leaves?

Was this to be seen in the seed?

How many leaves are there at each joint of stem after the first pair?
