The seeds planted in boxes will give ample means for observing how the seed starts to grow, how it gets out of the seed leaves, and how the stem and leaves develop from these. But to see the equally interesting and instruc- tive development of the root with its branches, root hairs and root cap, some other method of planting is necessary, since digging up the root destroys some of the very things necessary to be seen. For study of the growth of the root, plant a few seeds in earth confined be- tween two sheets of glass about seven by eight inches, or larger.
