Excerpt from Manual of Cultivated Plants Most Commonly Grown in the Continental United States and Canada Although the purpose of this book is to describe the species most commonly cultivated, there are three classes of rather marked excep tions: (1) Many plants not offered by dealers nor appearing in printed lists are in cultivation in old premises and private gardens, and are likely to be exchanged-from hand to hand; these plants have established themselves in the affections of growers and they should be recorded, even though not common or perhaps in the process of passing out in a commercial epoch. (2) Species of rather recent introduction that promise to be acquisitions but which are not yet well known; it is im possible to forecast which ones are likely to become fairly common or established. (3) Certain species of great historic interest in Europe and other countries that should be known as a matter of general knowledge but which may be little cultivated in North America; an example is Lupinus albus, lupine of the ancients and still grown in parts of Europe for human food, forage, and g'reen - manuring, but rarely seen in this country; in this category are many iood-plants likely at any time to awaken interest here and also such things as are frequently grown in economic collections these subjects are always interesting to students in the educational institutions. While some of the species in these three categories may not be common, they may nevertheless be significant to man or to the development of horticulture and agriculture, and there fore are in place in the book.
