Cornell Nature-Study Leaflets / Being a selection, with revision, from the teachers' leaflets, home nature-study lessons, junior naturalist monthlies and other publications from the College of Agriculture, Cornell University, Ithaca, N.Y., 1896-1904

by New York State College of Agriculture

1. How many colors do you find in one twig? Count the tints and shades. I found eight colors on a small maple branch ([Fig. 309]).

2. Notice the differences in several twigs as they lie on the table. What makes them look so different: size, shape, color, arrangement of buds, the size or shape of the buds?

Fig. 310. Horsechestnut.

Fig. 311. Butternut.

3. On how many twigs are the buds opposite each other? Note the opposite buds on the horsechestnut ([Fig. 310]). On how many are they alternate? Are the buds opposite on the butternut ([Fig. 311])?

4. Which twigs bear the buds singly?

5. When you find two or more buds growing together on a stem, is there any difference in the size of the buds?

6. On how many of the twigs can you see a scar left by the leaf when it dropped off ([Fig. 310] and [Fig. 311] a, a)? Compare the leaf scars on different twigs. Notice the strange scar on the butternut ([Fig. 311]). It looks like the face of an old sheep.
