March 2--That afternoon I planted the cabbage in a tin can with tissue
paper around it, because the cabbage outgrew the eggshell some time ago.
March 3--I put the plant out of the window.
March 4--I did not look at it.
March 5--One of the sprouts began to droop.
March 6--I dug the dirt up around it. Then it was put in the air out of
the window.
March 7--Holiday.
March 8--Holiday.
March 9--I put it out of the window.
March 10--It was put out of the window. It was brought in at the close
of school.
March 11--Dug the dirt out from the plant and patted it down.
March 12--Watered.
March 13--Put out of the window.
March 14--Holiday.
March 15--Holiday.
March 16--Watered and put out of the window. HELEN.
Was not this a good record for a little girl to make? I wish that she
had told something about the soil in which she planted the seeds. This
is always important. In winter you may have some difficulty in getting
soil, but in the village a florist will let you have some, and in the
country you may be able to get it in the cellar of a grocery store or
from your own cellar. Perhaps you can find some in the potato bin. When
there is a "thaw," get some soil, even if it is very wet; you can dry it
near the stove. Perhaps your schoolhouse will be too cold over Sunday in
mid-winter to allow you to grow plants. If so, plant the seeds at home.
When you have planted your seeds, unless you take them up every day, you
cannot see how the little plants are behaving down under the soil. I
want to tell you how you can know some things that the plants are doing
without disturbing them.
[Illustration: _Fig. 299. Radish seeds germinating between
blotting-paper and the side of a tumbler._]
Choose an ordinary glass (Fig. 299), roll up a piece of blotting paper
so that it is a trifle smaller than the glass, and place it inside.
Between the blotting paper and the glass, put a few radish seeds or any
kind of seed such as you planted in the soil. Keep the blotting paper
moist and watch what happens. In four or five days the plants should be
"up." Here are some things to think about as you watch them:
1. Note any change in the seeds when they have been moist for a few
hours.
2. What happens to the outer coat of the seed?
3. In what direction does the little root grow? The stem?
4. Notice the woolly growth on the root? Does this growth extend to the
tip of the root?
5. When the little plant has begun to grow, turn it around so that the
root is horizontal. Does it remain in that position?
6. How soon do the leaves appear?
It may interest some of the Junior Naturalists to see the effect of much
water on seeds. Suppose you experiment a little along this line. Choose
three glasses. In one put seeds into water, in another put them into
very wet or muddy soil, and in the third plant the seeds in moist soil,
such as seeds are ordinarily planted in. Tell us the results of the
three experiments.
A THIRD-GRADE RECORD.
