COTTON.-Here is the picture of a shrubby plant which is cultivated in warm countries for the fluffy fiber which surrounds its seeds. This fiber is called cotton. The seed is sown in March or April, and the cotton is gathered from August to December. The flowers vary in color with the different varieties-some being purple, others yellow, others a pinkish-white. As the petals drop off the seed-vessel or bole swells to the size of a large apple. It then bursts open, and the cotton is ready for the picking. As the seed-vessels ripen and burst open at different times on the same plant, the season for cotton-picking continues for some weeks. From the picture on the preceding page tell who the cotton pickers are and how they gather the cotton. The seeds are closely enveloped in the fiber, which is carried from the fields to the cotton-gin. Here the fiber is separated from the seeds. Describe what you see in the picture of a cotton-gin. It is then baled and

Plants are cultivated for many pur poses. Some are cultivated for their tries to ROOTS or TUBERS; some for their STALKS or STEMS; some for their LEAVES; some for BUDS and BLOSSOMS, and some for

their FRUIT or SEEDS.

Think what part of each of the plants which you know is used for food. Make a list of the plants which you know are raised for their leaves; for their stems-either as an article of food or fiber (the fiber of some plants is used for making cordage and cloths); for their roots or tubers; for bud or blossom; for seed; for fruit. Bring in pictures of the different plants which we eat. Also bring in specimens of those which grow in your neighborhood.

Go to the groceries, fruit-stores, and drugstore and find out what plant products are sold which come from sections having about the same seasons that we have. Which come from warmer countries; which from colder countries.

What plants give us our spices? Spices grow in countries which have hot weather for most of the year.

Bring in all kinds of spices. Find out from which part of the plant the spice is taken.

Name all the trees that you know which grow near your home or school.

Bring their leaves into school and tell where the trees are growing: on the hill, beside the water, or in the low land. What is their fruit?

Their seed? Bring specimens of fruit and seed to school. Find out how each tree scatters its seed. In what month and season does each blossom? In what month does each mature its fruit?

All the trees in the picture, and many others, drop their leaves in the fall.

Trees which drop their leaves in the fall

are called DECIDUOUS TREES.

How do people know this? What are the differences? Bring to school specimens of wood cut both horizontally and vertically. Find the heart-wood, the cells, and rings of growth, the outer and inner bark.

Find out which is hard and which is soft wood. For what is soft wood best adapted? Hard wood? Why is hard wood used for ship-building?

Leave a twig and the stem end of a leaf in some red ink for a time. Observe the effect. From this experiment you will learn how the sap, or nourishment, gets to the growing part of the tree.

Note carefully the shapes of the leaves, the manner of growth on the tree. Note where they branch, if high or low. Draw their curves or 'lines of growth." Find out what kind of roots

the trees have.

All foliage is arranged to allow the greatest amount of air and sunlight to reach every part of the tree.
