In closing this talk with you, we wish to emphasize one point brought
before you. Here is a pencil, a real thing; we carry in memory a picture of
the pencil, which we call an idea; and there are the two words naming this
idea, the spoken and the written. Learn to distinguish clearly these four
things.

TO THE TEACHER.--In reviewing these three Lessons, put particular emphasis
on Lesson 2.

LESSON 4.

ANALYSIS AND THE DIAGRAM.

TO THE TEACHER.--If the pupils have been through "Graded Lessons" or its
equivalent, some of the following Lessons may be passed over rapidly.

+DEFINITION.--A _Sentence_ is the expression of a thought in words+.

+Direction+.--_Analyze the following sentences_:--

+Model+.--_Spiders spin_. Why is this a sentence? Ans.--Because it
expresses a thought. Of what is something thought? Ans.--Spiders. Which
word tells what is thought? Ans.--_Spin_. [Footnote: The word _spiders_,
standing in Roman, names our idea of the real thing; _spin_, used merely as
a word, is in Italics. This use of Italics the teacher and the pupil will
please note here and elsewhere.]
