lly become accustomed to describe
whatever they can see. They have, at any rate, used their eyes; and,
though they may not understand the real meaning of anything they have
seen, they are prepared to discuss the subject intelligently when they
come together in the class. If they will first write out their unassisted
impressions and, subsequently, an account of the same thing after they
have had a recitation upon it, they will be sure to gain something in the
power of observation and clear expression. It cannot be too strongly
urged that the number of facts that the children may learn is not of the
slightest consequence, but that the teacher should aim to cultivate the
quick eye, the ready hand, and the clear reason.

The root of the Morning-Glory is _primary_; it is a direct downward growth
from the tip of the caulicle. It is about as thick as the stem, tapers
towards the end, and has short and fibrous branches. In some plants the
root keeps on growing and makes a _tap-root_; in the Bean, it soon becomes
lost in the branches. These are all simple, that is, there is but one
primary root. Sometimes there are several or many, and the root is then
said to be _multiple_. The Pumpkin is an example of this. The root of
the Pea is described in the older editions of Gray's Lessons as being
multiple, but it is generally simple. Indian Corn, also, usually starts
with a single root, but this does not make a tap-root, and is soon
followed by many others from any part of the caulicle, or even from the
stem above, giving it the appearance of having a multiple root.

The root of the Radish is different from any of these; it is _fleshy_.
Often, it tapers suddenly at the bottom into a root like that of
the Morning-Glory with some fibres upon it. It is, in fact, as the
Morning-Glory would be if the main root were to be thickened up by
food being stored in it. It is a primary tap-root. The radish is
_spindle-shaped_, tapering at top and bottom, the carrot is _conical_, the
turnip is called _napiform_; some radishes are shaped like the turnip.

The aerial roots of the English Ivy answer another purpose than that of
giving nourishment to the plant. They are used to support it in climbing.
These are an example of _secondary_ roots, which are roots springing
laterally from any part of the stem. The Sweet Potato has both fleshy and
fibrous roots and forms secondary roots of both kinds every year.[1] Some
of the seedlings will probably show the
