Material. Blackberry and horse-radish roots and planted cuttings of each.

Many plants can be multiplied with ease by means of short cuttings of the roots. True root cuttings possess no buds at all, but buds develop after the cutting is planted. The roots are cut into pieces from one inch to three inches in length and planted horizontally.

Fig. 8. Root cuttings of the horse-radish.

1. Secure roots of the blackberry and horse-radish, both of which are easily propagated by root cuttings. Practice making a number of these cuttings. Make a natural-size drawing of a root cutting from each of the plants. Look carefully for buds. Can any be found? Now secure cuttings of the above that have been planted for some little time. Examine these for buds. Where are the buds found? Make a drawing showing the bud, and differentiate between the two cuttings. Discuss.
