All \‘ines, and plants with runners or long and slender shoots
that fall to the ground, may be multiplied readily by layerage.
Among fruits, the black-cap raspberry and dewberry are familiar
examples. The raspberry canes of the current year bend over
late in summer and the tips strike the earth. If the tip is
schc’ured by a slight covering of earth, or if it finds lodgment
in a mellow soil, roots are formed, and in autumn a strong bud
