What's wrong with this sentence? (A passage from Heart of Darkness) -2

What's wrong with this sentence?

Nothing... “The fault, dear Brutus, is not in our stars / But in ourselves, ….” (Shakespeare: Julius Caesar, Act I, Scene III, L. 140-141).

The things that are “wrong” with it are those that you have not encountered before. There is nothing wrong with the use of English:

Flood = the flood tide; the incoming tide; the rising tide. (The converse is “the ebb”)

“To make” is used in an unusual but valid sense. It is the intransitive form of the verb to make.

OED:

To make: 58. a. intransitive. Nautical. Of the flood or ebb tide: to begin to flow or ebb respectively; (also) to be in progress. Hence, of the tide: to flow towards the land; to rise; (also) to flow in a specified direction. Of wind: to increase in strength.

1883 R. L. Stevenson Treasure Island iv. xvii. 135 The ebb was now making.
