Sentry-Box

Man may, in effect, be said to look out on the world from a sentry-box with two joined sashes for his window. But with the whale, these two sashes are separately inserted, making two distinct windows, but sadly impairing the view. This peculiarity of the whale’s eyes is a thing always to be borne in mind in the fishery; and to be remembered by the reader in some subsequent scenes.

And this it was, this same unaccountable, cunning life-principle in him; this it was, that kept him a great part of the time soliloquizing; but only like an unreasoning wheel, which also hummingly soliloquizes; or rather, his body was a sentry-box and this soliloquizer on guard there, and talking all the time to keep himself awake.
