Read it through once

At eight o'clock, promptly, we backed out and crossed the river. As we crept toward the shore, in the thick darkness, a blinding glory of white electric light burst suddenly from our forecastle, and lit up the water and the warehouses as with a noon-day glare. Another big change, this--no more flickering, smoky, pitch-dripping, ineffectual torch-baskets, now: their day is past. Next, instead of calling out a score of hands to man the stage, a couple of men and a hatful of steam lowered it from the derrick where it was suspended, launched it, deposited it in just the right spot, and the whole thing was over and done with before a mate in the olden time could have got his profanity-mill adjusted to begin the preparatory services. Why this new and simple method of handling the stages was not thought of when the first steamboat was built, is a mystery which helps one to realize what a dull-witted slug the average human being is.
