drooping flowers, figuratively speaking

Prostrate here and there over the bones of Donjalolo's sires, the royal bacchanals lay slumbering till noon.

"Which are the deadest?" said Babbalanja, peeping in, "the live kings, or the dead ones?"

But the former were drooping flowers sought to be revived by watering....
(Mardi)

There are times thus, on the dullest march,and in the dullest life elsewhere, —when, as by accident, a general excitement comes, as the sudden whirlwind when the sun is reigning with the calmest tyranny; delightfully refreshing, like a shower to drooping flowers, they give our souls new spirit and power to rise from the moral drought of routine and dull material life.

innocence before tyrants

Well, I mean that fanatics, hypocrites, and malicious gossips generally rule society : sometimes under the cloak of religion, sometimes as envious, presumptuous censors, they intimidate the true and innocent, who resist not, nor despise, — but slavishly cower before their unblushing falsehood....

(Scenes Beyond the Western Border, August 1852; and
Scenes and Adventures in the Army, 355)

The imputation of tyranny is no great stretch from "intimidate" and "slavishly cower." In the book version, the synoptic Table of Contents describes this section as "Tyranny of Society and Fashion."

Like an icicle-dagger, Goneril at once stabbed and froze; so at least they said; and when she saw frankness and innocence tyrannized into sad nervousness under her spell, according to the same authority, inly she chewed her blue clay, and you could mark that she chuckled.  (The Confidence-man)

the commodore in his cabin

  

"... in his grand, inaccessible cabin, the high and mighty commodore sat silent and stately, as the statue of Jupiter in Dodona." -- Herman Melville, White-Jacket; Or The World in a Man-of-War (1850) 

* * * 

How dreary must be a great Commodore
Alone in the cabin of a seventy-four. 

Be not alarmed! I make a rhyme but once a year; the idea came in that shape, and you must take it as it comes. -- Scenes Beyond the Western Border, June 1851

immortalize this

My tragedy is all true,—and if not quite serious, has, as is proper, its moral;—but rather, as I have alluded to the primitive tragedy, let that "future reader" here imagine the entry of Chorus, and their song to Freedom! That dumb beasts prefer death to slavery! Liberty lost, they can die without the excitement of the world's applause, or hopes of a grateful posterity! (It is not possible, I think, that the cub could have known that I would immortalize him.)

"And that immortalized Rondo, no doubt," said Babbalanja. "Ha! ha!"  (Mardi)

BABBALANJA--Probably some one who lived in Lombardo's time, and went by that name. He is incidentally mentioned, and cursorily immortalized in one of the posthumous notes to the Koztanza.  (Mardi)

they finally succeeded in immortalizing themselves by quenching their mortalities all round; the bards still singing.  (Mardi)

It was a curious and remarkable book; and from the many fond associations connected with it, I should like to immortalize it, if I could. (Redburn)

In plain prose, Selvagee was one of those officers whom the sight of a trim-fitting naval coat had captivated in the days of his youth. He fancied, that if a sea-officer dressed well, and conversed genteelly, he would abundantly uphold the honour of his flag, and immortalize the tailor that made him. (White-Jacket)

How natural then the inference, that instead, as in old times, immortalizing a genius, a portrait now only dayalized a dunce. (Pierre)

It was the famous pilot, Juan Fernandez, immortalized by the island named after him....
(Encantadas)

... only, is it certain that I can get to Baltimore the day following in time to immortalise myself there also?  (Letter to George L. Duyckinck, 20 December 1858)

'Bravissimo!' 
'Encore!' 
'Write it out, Major!'
'Put it in verse!' 
'Good, it will immortalise thee!'
(Sketch of Jack Gentian in Great Short Works)

towering rage

"My dunderfunk, sir—as elegant a dish of dunderfunk as you ever see, sir—they stole it, sir!"

"Go forward, you rascal!" cried the Lieutenant, in a towering rage, "or else stop your whining. Tell me, what's the matter?"

"Why, sir, them 'ere two fellows, Dobs and Hodnose, stole my dunderfunk."
(White-Jacket)

“Can’t sell his head?—What sort of a bamboozingly story is this you are telling me?” getting into a towering rage. “Do you pretend to say, landlord, that this harpooneer is actually engaged this blessed Saturday night, or rather Sunday morning, in peddling his head around this town?”
(Moby-Dick, Chapter 3)

... that an innocent brother, (or sister,) being ruthlessly slain, and the baffled lady-mother left (unceremoniously) full of towering and demonstrative rage,— the imprisoned hero himself sank overwhelmed,—or in a well-acted counterfeit of death....
("Scenes Beyond the Western Border," March 1853)

In each instance the context is dramatic and comic, the rage lightly treated as part of the running joke.

so be it

"From storm to storm! So be it, then. Born in throes, 't is fit that man should live in pains and die in pangs! So be it, then! Here's stout stuff for woe to work on. So be it, then." (Moby-Dick, November 1851)

C. "But who lives, who may not be wounded through another!—Then so be it! let us treat the whole world as it has done us, and—forget it! I dare say, nay, I am sure, that beyond some family ties, there is not upon the wide earth a heart in sympathy with our good or ill; whose even beat would be as much disturbed, were this wild sod to cover us forever, as at the most ephemeral of the trifling cares which make up their petty lives." 
(Scenes Beyond the Western Border, August 1852)

Amigo

"Amigo Mio! Didn't you desert me on the eve of a snow storm, like many another friend of so honest mouthing! And is a touch of poetry a bad companion in difficulty and trial? Never a bit; it was the boon of a God — Wisdom was ever feminine."

(Scenes Beyond the Western Border, April 1852; and
Scenes and Adventures in the Army)

"Your bivouac was marvellously like this present one! But go on; and — if you do not stop at a dream or two — you will doubtless soon come to the cream of the story."

"Amigo mio. — My dreams are — not what they were! "
(September 1852; and Scenes and Adventures)

Amigo, do not scourge me on;
Put up, put up your monkish thong!

"Amigo, how you persecute!"

"Amigo! favored lads there are,
Born under such a lucky star,
They weigh not things too curious, see,
Albeit conforming to their time
And usages thereof, and clime: 
Well, mine's that happy family."
(The sensual poetical "Lyonese" in Clarel 4, Canto 26)

"Time, Amigo, does but mask us —" (L'Envoi from Weeds and Wildings)
