CHAPTER
V
PROPAGATIQN BY MEANS OF CUTTINGS
THE regular growth-shoots of plants may grow when severed
and placed in earth ; as they are cut from the parent, so are
such parts known as clrttiuga. Tubers and dorm;] rlt shoots
:-lrtr! leaves, and cvcn parts of fruits as in certain cact,i, may
also yiel(l nnwteri:~ls for cuttings, propagating the plant. The
practice or process of multiplying plants by cuttings, with
all the craft and science pertaining thereto, is denominated
twtta.gc. To this entertaining department we now address
ourselves.

a porous soil, and sometimes bottom heat.. The
requirements vary greatly with the dif-ferent. kinds of plants,

in specific application.

To secure a uniform and moist atmosphere, various propagat-

mg-frames are in common use. These frames and boxes or
bell-glasses may be used also for seed propagation, but as they
find their greatest application in cuttage, they are described
mostly in this chapter.
Whatever its construction, the frame should be sufficiently
tight to confine the air closely ; it should admit light, and allow
