If there be more shell-rooms than there are disposable Quarter Gunners to attend them, other careful and suitable persons are to be selected to supply the deficiency.

83. Before permanently assigning the individuals which form a gun's crew, to the performance of particular duties connected with its service in action, it is important to ascertain their respective qualifications, as far as may be practicable, by questioning them or by exercising them at the guns.

84. The Captains, especially, should be selected from those in whose skill, coolness, and judgment the greatest reliance can be placed, without regard to their ratings, though at the same time care should be taken to avoid stationing men of a higher rating than the Captains of the guns, to perform subordinate duties at the same guns. They should be examined by the Surgeon with reference to eyesight.

Spongers and Loaders rank next in importance, and, with activity and coolness, should possess the necessary physical strength and stature. For Handspikemen, weight is important, in addition to strength and coolness.

85. Very careful men should be selected for attending the Powder-scuttles on the different decks, as well to prevent noise and contention among the Powder-boys as to guard against accidents, and speedily to repair such as may occur. The boys should be trained to fall into line, to insure an equal distribution of powder.

86. Unless some special reason should require a different arrangement with regard to Boarders, Pikemen, Firemen, Sail-trimmers, and Pumpmen, the following will be observed:

BOARDERS.

87. Half the men composing a gun's crew, excluding the Powderman or Boy, are to be Boarders. When this rule gives an odd number of men, the odd one is to be a Second Boarder.

88. The Boarders are to constitute two divisions, called First and Second Boarders.

89. First Boarders are, generally, to be taken from the second part of a gun's crew; and Second Boarders from the first part.
