The sentences used in connection with the lessons may be used in a
variety of ways:
(_a_) They are placed in the book primarily for the purpose of
illustrating the use of the word.
(_b_) They have been very carefully selected from our best authors and
many of them may wisely be memorized.
(_c_) They may be used as dictation exercises. In this case misspelled
words should be counted as errors. All other mistakes should be
corrected by referring to the book but should not be counted against the
child as an error in spelling.
