altogether.
[Footnote 2: The large Russian Sunflower is the best for the purpose.] [Footnote 3: These lessons are intended, as has been said, for children over twelve years of age. If they are adapted for younger ones, it is especially important to begin with a seed where the leaf-like character of the cotyledons is evident, or becomes so. Maple is excellent for the purpose. Morning-Glory is too small. Squash will answer very well. I think it characteristic of the minds of little children to associate a term with the first specimen to which it is applied. If the term cotyledon be given them first for those of the Bean and Pea they will say when they come to the Morning-Glory, "but those are _leaves_, not cotyledons. Cotyledons are large and round." It will be very difficult to make them understand that cotyledons are the first seed-leaves, and they will feel as if it were a forced connection, and one that they cannot see for themselves.] The teacher's object now is to make the pupils understand the meaning of the answers they have given to these questions. In the first place, they should go over their answers and substitute the botanical terms they have just learned for the ones they have used. COMPARISON OF THE PARTS OF THE SOAKED SEEDS. _Morning-Glory_. A seed covering. Some albumen. Two cotyledons. A caulicle. _Sunflower_. An outer covering.[1] An inner covering. Two cotyledons. A caulicle.[2] |
