The number contained in a square pile is found in the column opposite
the number X.

In a rectangular pile let the smaller side be 19 = X, the longer side
be 26 = X + N. Then N = 7. Under 7 and opposite 19 we have 3,800. This
table may be indefinitely extended by the aid of the columns of
differences.

PRESERVATION OF SHOT AND EMPTY SHELL.

98. All round shot and shell are to be cleaned from rust and covered
with a thin lacquer of such composition as may be directed by the
Bureau when they are first received and when they are restowed.

99. For the present the following colors are established when put on
board ship: All shot, black; shell, red; shrapnel, white; length of
fuze stencilled on the shell. Special kinds of shell, as may be
directed by Bureau. (Crane's shell, yellow; Pevey, blue.)

100. Empty shell, whether in store or in transportation, shall be most
carefully protected from damp, and are to have the fuze-bouching
coated with such composition as may be directed, and be stopped by a
plug of very soft wood, well coated with a mixture of oil and tallow,
screwed into them. The ends of the plugs should not be sawed off even
with the shell, but left square and project sufficiently to allow them
to be unscrewed by means of a wrench, and whenever these plugs are
removed for the purpose of fitting the shells for service, they are
not to be thrown away but preserved for future use.

They are to be piled with the fuze-holes down, and free from contact;
under cover when practicable, but with free ventilation.

101. Platforms of masonry, or of condemned shot, are to be prepared to
pile shot and shell upon, and are not to be wider, if space can be
found than to stow fourteen 32-pdr. shot, or not exceeding eight feet
in width. Square piles are to be preferred where there is room, but
where this may be deficient, the piles may be extended in length.

102. Shot and shell, after having been piled, are to be so far
examined in the first week of June in each year as to ascertain if
they require to be cleaned, relacquered, and repiled to secure their
proper preservation; and their condition reported to the Bureau, that
if any work upon them is necessary it may be
