nospora cones were taken from the "Gardener's Chronicle"; and
three of the illustrations in Part I. are from Professor Gray's works.

The size of the illustration as compared with the specimen of plant is
indicated by a fraction near it; 1/4 indicates that the drawing is one
fourth as long as the original, 1/1 that it is natural size, etc. The
notching of the margin is reduced to the same extent; so a margin which
in the engraving looks about entire, might in the leaf be quite
distinctly serrate. The only cases in which the scale is not given are
in the cross-sections of the leaves among the figures of coniferous
plants. These are uniformly three times the natural size, except the
section of Araucaria imbricata, which is not increased in scale.

The author has drawn from every available source of information, and in
the description of many of the species no attempt whatever has been made
to change the excellent wording of such authors as Gray, Loudon, etc.

The ground covered by the book is that of the wild and cultivated trees
found east of the Rocky Mountains, and north of the southern boundary of
Virginia and Missouri. It contains not only the native species, but all
those that are successfully cultivated in the whole region; thus
including all the species of Ontario, Quebec, etc., on the north, and
many species, both wild and cultivated, of the Southern States and the
Pacific coast. In fact, the work will be found to contain so large a
proportion of the trees of the Southern States as to make it very useful
in the schools of that section.

Many shrubby plants are introduced; some because they occasionally grow
quite tree-like, others because they can readily be trimmed into
tree-forms, others because they grow very tall, and still others because
they are trees in the Southern States.

In nomenclature a conservative course has been adopted. The most
extensively used text-book on the subject of Botany, "Gray's Manual,"
has recently been rewritten. That work includes every species, native
and naturalized, of the region covered by this book, and the names as
given in that edition have been used in all cases.

Scientific names are marked so as to indicate the pronunciation. The
vowel of the accented syllable is marked by the grave accent (`) if
long, and by the acute (') if short.

In the preparation of this book the author has received much valuable
aid. His thanks are especially due to the authorities of the Arno
