The ship had been at sea many weeks. A great strain on master and men. An increasing callous indifference in the men, an increasing irritability in the master.
Don't expect me to say _why_ storms must be. They just are. Storms in the air, storms in the water, storms of thunder, storms of anger. Storms just are.
Storms are a sort of violent readjustment in some polarized flow. You have a polarized circuit, a circuit of unstable equilibrium. The instability increases till there is a crash. Everything seems to break down. Thunder roars, lightning flashes. The master roars, the whip whizzes. The sky sends down sweet rain. The ship knows a new strange stillness, a readjustment, a refinding of equilibrium.
Ask the Lord Almighty why it is so. I don't know. I know it is so.
But flogging? Why flogging? Why not use reason or take away jam for tea?
Why not? Why not ask the thunder please to abstain from this physical violence of crashing and thumping, please to swale away like thawing snow.
Sometimes the thunder _does_ swale away like thawing snow, and then you hate it. Muggy, sluggish, inert, dreary sky.
You have a Sam, a fat slow fellow, who has got slower and more slovenly as the weeks wear on. You have a master who has grown more irritable in his authority. Till Sam becomes simply wallowing in his slackness, makes your gorge rise. And the master is on red hot iron.
Now these two men, Captain and Sam, are there in a very unsteady equilibrium of command and obedience. A polarized flow. Definitely polarized.
The poles of will are the great ganglia of the voluntary nerve system, located beside the spinal column, in the back. From the poles of will in the backbone of the Captain, to the ganglia of will in the back of the sloucher Sam, runs a frazzled, jagged current, a staggering circuit of vital electricity. This circuit gets one jolt too many, and there is an explosion.
"Tie up that lousy swine!" roars the enraged Captain.
And whack! Whack! down on the bare back of that sloucher Sam comes the cat.
What does it do? By Jove, it goes like ice-cold water into his spine. Down those lashes runs the current of the Captain's rage, right into the blood and into the toneless ganglia of Sam's voluntary system. Crash! Crash! runs the lightning flame, right into the cores of the living nerves.
