ll the sheet can be
split by the top surface being removed.

The best plan, however, is to paste a piece of cloth or strong paper to
each side of the sheet to be split. When dry, quickly, and without
hesitation, pull the two pieces asunder, when one part of the sheet will
be found to have adhered to one, and part to the other. Soften the paste
in water, and the two pieces can easily be removed from the cloth.

+Theme LXXXV.+--_Select for a subject something that you know how to do.
Write a theme on the subject chosen._

(Have you made use of either general description or general narration? See
Sections 67 and 68.)

Very frequently explanations of _how_ and _why_ anything is done are
combined, as in the following:--

In cases of sunstroke, place the person attacked in a cool, airy place. Do
not allow a crowd to collect closely about him. Remove his clothing, and
lay him flat upon his back. Dash him all over with cold water--ice-water,
if it can be obtained--and rub the entire body with pieces of ice. This
treatment is used to reduce the heat of the body, for in all cases of
sunstroke the temperature of the body is greatly increased. When the body
has become cooler, wipe it dry and remove the person to a dry locality. If
respiration ceases, or becomes exceedingly slow, practice artificial
respiration. After the patient has apparently recovered, he should be kept
quiet in bed for some time.

Notice that the following selection answers neither the question _how_?
nor _why_? but explains what journalism is:--

JOURNALISM

What is a journal? What is a journalist? What is journalism? Is it a
trade, a commercial business, or a profession? Our word _journal_ comes
from the French. It has different forms in the several Romantic languages,
