lima beans are an instance of what is meant. While limas have always
been appreciated as one of the most delicious of vegetables, in many
sections they could never be successfully grown, because of their
aversion to dampness and cold, and of the long season required to
mature them. The newer sorts are not only larger and better, but
hardier and earlier; and the bush forms have made them still more
generally available.

Knowledge on the subject of gardening is also more widely diffused than
ever before, and the science of photography has helped wonderfully in
telling the newcomer how to do things. It has also lent an impetus and
furnished an inspiration which words alone could never have done. If
one were to attempt to read all the gardening instructions and
suggestions being published, he would have no time left to practice
gardening at all. Why then, the reader may ask at this point, another
garden book? It is a pertinent question, and it is right that an answer
be expected in advance. The reason, then, is this: while there are
garden books in plenty, most of them pay more attention to the
"content" than to the form in which it is laid before the prospective
gardener. The material is often presented as an accumulation of detail,
instead of by a systematic and constructive plan which will take the
reader step by step through the work to be done, and make clear
constantly both the principles and the practice of garden making and
management, and at the same time avoid every digression unnecessary
from the practical point of view. Other books again, are either so
elementary as to be of little use where gardening is done without
gloves, or too elaborate, however accurate and worthy in other
respects, for an every-day working manual. The author feels, therefore,
that there is a distinct field for the present book.
