Excerpt: ...ripen well, harvest carefully, and afterwards dress the grain over two or three times with the most suitable dressing machine, so that only the very best grain be retained. If this system is persevered in, a better crop will result than from an annual change of seed. Cross-itertilisation. In order to produce a variety of plant which shall combine the good characteristics of two separate kinds, the system of cross-breeding has been largely practised, especially with wheat. On one of the selected parent plants the glumes are opened and the anthers removed some time before these latter are ripe. When the pollen is ripe for shedding in the other parent plant, it is dusted over the feathery stigmas of the young germ in the plant first operated on, the glumes closed, and the heads tied up in muslin, to protect from birds, &c. The operation requires much careful manipulation, and the delicate organs must not be exposed to the weather; while it requires to be done early, as self-fertilisation naturally takes place inside the glumes, some time before the empty anthers are pushed outside, "Cross-bred " varieties are now common.
