waking thoughts, and trouble you in your dreams. You will lose all
command of your powers, and, besides cutting off from yourself all hope
of general intellectual progress, you will, in fact, destroy your
success as a teacher. Exhaustion, weariness, and anxiety will be your
continual portion, and in such a state no business can be successfully
prosecuted.

There need be no fear that employers will be dissatisfied if the teacher
acts upon this principle. If he is faithful, and enters with all his
heart into the discharge of his duties during six hours, there will be
something in the ardor, and alacrity, and spirit with which his duties
will be performed which parents and scholars will both be very glad to
receive in exchange for the languid, and dull, and heartless toil in
which the other method must sooner or later result.

If the teacher, then, will confine himself to such a portion of time as
is, in fact, all he can advantageously employ, there will be much left
which can be devoted to his own private employment--more than is usual
in the other avocations of life. In most of these other avocations there
is not the same necessity for limiting the hours which a man may devote
to his business. A merchant, for example, may be employed nearly all the
day at his counting-room, and so may a mechanic. A physician may spend
all his waking hours in visiting patients, and feel little more than
healthy fatigue. The reason is, that in all these employments, and, in
fact, in most of the employments of life, there is so much to diversify,
so many little incidents constantly occurring to animate and relieve,
and so much bodily exercise, which alternates with and suspends the
fatigues of the mind, that the labors may be much longer continued, and
with less cessation, and yet the health not suffer. But the teacher,
while engaged in his work, has his mind continually on the stretch.
There is little relief, little respite, and he is almost entirely
deprived of bodily exercise. He must, consequently, limit his hours of
attending to his business, or his health will soon sink under labors
which Providence never intended the human mind to bear.

There is another circumstance which facilitates the progress of the
teacher. It is a fact that all this general progress has a direct and
immediate bearing upon his pursuits. A lawyer may read in an evening an
interesting book of travels, and find nothing
