g lessons.[40] This will in a short time be easy
for them; and to ensure the preparation, the name of each pupil ought to
be kept on a separate card, and these being shuffled, the teacher, after
asking the question at the whole, may take the upmost card, and require
that child to answer it. All must in that case be prepared, as none can
know but he may be the person who shall be called on publicly to answer.
The application of the lessons will be found the most useful, and to the
children the most interesting part of this exercise. In this the teacher
supposes a circumstance, or situation, corresponding to the lesson
drawn, in which the pupils may be placed; and he requires them to say
how they ought to act in such a case. When they give their _opinion_,
they must then give their _authority_; that is, they must refer to the
lesson, and through the lesson, to the Scripture truth from which it was
drawn.

_Natural Philosophy._--In teaching the principles of _Natural
Philosophy_, a select class may be formed, more circumscribed as to
number, and from among the more advanced scholars. To these, a section,
or part of section, of the "First Step to Natural Philosophy," is to be
given to prepare at home,--to understand, and to be ready to draw and
apply the lessons,--in a manner similar to that prescribed above, and as
illustrated in the Key to that work.

_Writing._--In teaching the art of _Writing_, upon the preceding
principles, the chief object is to train the pupils easily and readily
to _write down their own thoughts_. To accomplish this, a certain
portion of their time may be occupied as follows. The teacher reads a
sentence, or a paragraph, or, what will perhaps be better, a short
story, or anecdote, and requires the whole of them to write it down in
their _books_ for after examination. These of course are to be examined
and corrected, with any necessary remarks by the teacher or
assistant.--In this exercise, there is no necessity for circumscribing
the pupils as to time,--it being required that they write accurately,
grammatically, and neatly, whether in large or small text. To all those
who are first finished, some other exercise ought to be provided that
they may in that manner usefully occupy the time that may remain of
their hour.

_Arithmetic._--The introduction of the Arithmetic Rod, and its Key, into
a school, will be productive of many advantages.[41] The line of figures
upon the A side of the Rod, being pa
