Wires of underground influence

Teaching Billy Budd next week, I'm excited:

About as much was really known to the Bellipotent's tars of the master-at-arms' career before entering the service as an astronomer knows about a comet's travels prior to its first observable appearance in the sky. The verdict of the sea quidnuncs has been cited only by way of showing what sort of moral impression the man made upon rude uncultivated natures whose conceptions of human wickedness were necessarily of the narrowest, limited to ideas of vulgar rascality--a thief among the swinging hammocks during a night watch, or the man-brokers and land-sharks of the seaports.

It was no gossip, however, but fact that though, as before hinted, Claggart upon his entrance into the navy was, as a novice, assigned to the least honorable section of a man-of-war's crew, embracing the drudgery, he did not long remain there. The superior capacity he immediately evinced, his constitutional sobriety, an ingratiating deference to superiors, together with a peculiar ferreting genius manifested on a singular occasion; all this, capped by a certain austere patriotism, abruptly advanced him to the position of master-at-arms.

Of this maritime chief of police the ship's corporals, so called, were the immediate subordinates, and compliant ones; and this, as is to be noted in some business departments ashore, almost to a degree inconsistent with entire moral volition. His place put various converging wires of underground influence under the chief's control, capable when astutely worked through his understrappers of operating to the mysterious discomfort, if nothing worse, of any of the sea commonalty.
