1 Call me Ishmael. 2 Some years ago—never mind how long precisely—having little or no money in my purse, and nothing particular to interest me on shore, I thought I would sail about a little and see the watery part of the world. 3 It is a way I have of driving off the spleen and regulating the circulation. 4 Whenever I find myself growing grim about the mouth; whenever it is a damp, drizzly November in my soul; whenever I find myself involuntarily pausing before coffin warehouses, and bringing up the rear of every funeral I meet; and especially whenever my hypos get such an upper hand of me, that it requires a strong moral principle to prevent me from deliberately stepping into the street, and methodically knocking people’s hats off—then, I account it high time to get to sea as soon as I can. 5 This is my substitute for pistol and ball. 6 With a philosophical flourish Cato throws himself upon his sword; I quietly take to the ship. 7 There is nothing surprising in this. 8 If they but knew it, almost all men in their degree, some time or other, cherish very nearly the same feelings towards the ocean with me.

9 There now is your insular city of the Manhattoes, belted round by wharves as Indian isles by coral reefs—commerce surrounds it with her surf. 10 Right and left, the streets take you waterward. 11 Its extreme downtown is the battery, where that noble mole is washed by waves, and cooled by breezes, which a few hours previous were out of sight of land. 12 Look at the crowds of water-gazers there.

Based on the context of the passage, what does “driving off the spleen” (Sentence 3) likely mean?

Sentence 10 conveys an impression of _______________.

1 I have just returned from a visit to my landlord—the solitary neighbour that I shall be troubled with.  2 This is certainly a beautiful country!  3 In all England, I do not believe that I could have fixed on a situation so completely removed from the stir of society.  4 A perfect misanthropist’s heaven: and Mr. Heathcliff and I are such a suitable pair to divide the desolation between us.  5 A capital fellow!  6 He little imagined how my heart warmed towards him when I beheld his black eyes withdraw so suspiciously under their brows, as I rode up, and when his fingers sheltered themselves, with a jealous resolution, still further in his waistcoat, as I announced my name.

… 7 [he] sullenly preceded me up the causeway, calling, as we entered the court,—‘Joseph, take Mr. Lockwood’s horse; and bring up some wine.’

 … 8 Joseph was an elderly, nay, an old man: very old, perhaps, though hale and sinewy.  9 ‘The Lord help us!’ he soliloquised in an undertone of peevish displeasure, while relieving me of my horse: looking, meantime, in my face so sourly that I charitably conjectured he must have need of divine aid to digest his dinner.

What idea does “charitably conjectured” imply in the context of Sentence 9?
