Read it through once

A few years before the outbreak of the Civil War it began to appear that Memphis, Tennessee, was going to be a great tobacco entrepot—the wise could see the signs of it. At that time Memphis had a wharf boat, of course. There was a paved sloping wharf, for the accommodation of freight, but the steamers landed on the outside of the wharfboat, and all loading and unloading was done across it, between steamer and shore. A number of wharfboat clerks were needed, and part of the time, every day, they were very busy, and part of the time tediously idle. They were boiling over with youth and spirits, and they had to make the intervals of idleness endurable in some way; and as a rule, they did it by contriving practical jokes and playing them upon each other.
