The drainage was in surface gutters, and in them the water stood nearly still.

It seemed to me such water must have yellow fever in it.
For a long way along the levee the steamboats lay thick and close together, unloading cotton, hemp, sugar, hoop poles, bacon and other products, mostly the product of negro labor.
Here our friend Evans was taken sick, and as he got no better after a day or two, we called a doctor to examine him.

He pronounced it a mild case of yellow fever.

His skin was yellow in places, and he looked very badly.

The doctor advised us to go on up the river, saying it was very dangerous staying here with him.
