And, too, in the case of a steamer of any kind, about one-third of B will also be the proportion of hands to be taken for the Master's division; but the rest, less those just mentioned for the Surgeon's division, is to be increased by one-third of the number of firemen and coal-heavers allowed, to constitute the powder division.
It is to be borne in mind that the powder division is always to command a preference over the master's, on the score of being sufficiently manned.
3. Add A and B together, and call their sum C.
4. To ascertain how many of the whole number of C are to be petty officers, &c., consult Table II.
5. One-sixth part of the whole number of C will give the number of seamen.
6. One-fourth part of the whole number of C will give the number of ordinary seamen.
7. One-fortieth part of the whole number of C will give the number of musicians (exclusive of the master of the band), when musicians are allowed, which is to be only to ships-of-the-line, frigates, and flag vessels having a totality of crew amounting to not less than 350 souls.[2]
8. The total number of petty officers, &c., seamen, ordinary seamen, and musicians, deducted from the whole number of C, will give the number of landsmen and boys.
9. The number of hands, in addition to the whole number of C, to serve as firemen and coal-heavers, when these are required, is to be ascertained by the annexed rule relating to the subject.
10. For the number and grades of officers, consult Table III.
