Note 77 — Front matter (continued 4)
Reading edition
'Landmen' or 'Landsmen,' 'Ordinary Seamen,' and 'Able Seamen' or 'A.B.s' were the three classes or ratings into which men before the mast were divided, usually according to ability and length of service. 'A.B.' was the highest rating, entitling those of the rate to increased pay, and affording opportunities for promotion.
