PART II.

PLAN AND MODELS FOR TREE DESCRIPTION

All pupils should be required to write some form of composition on the
trees of the region. As far as possible, these compositions should be
the result of personal investigation. It is not what a pupil can read
and redescribe in more or less his own words, but how accurately he can
see and, from the information conveyed by his own senses, describe in
his own way the things he has observed, that makes the use of such a
book as this important as an educational aid. Some information in regard
to trees, in a finished description, must be obtained from books, such
as hardiness, geographical distribution, etc. Pupils generally should be
required to include only those things which they can give from actual
observation.

There are four distinct forms of tree descriptions that might be
recognized by the teacher and occasionally called for as work from the
pupil. 1st. A bare skeleton description, written by aid of a topical
outline, from the observation of a single tree and its parts. 2d. A
connected description, conveying as many facts given in the outline as
can well be brought into good English sentences. This again is the
description of a single tree. 3d. A connected, readable description of a
certain kind of tree, made up from the observation of many trees of the
same species to be found in the neighborhood. 4th. The third description
including
