A Virginia citizen was brought in on the charge of attempting to trade in "greenbacks,"—a penitentiary offense under Confederate law. Before he had been in our room five minutes one of the sub-wardens entered, asking:

"Is there anybody here who has 'greenbacks?' I am paying four dollars for one to-day."

The negroes were used for scrubbing and carrying messages from the office of the prison to the different apartments. Invariably our friends, they surreptitiously conveyed notes to acquaintances in the other rooms, and often to Unionists outside.

A Negro Cruelly Whipped.

While we were at Libby, an intelligent mulatto prisoner from Philadelphia was whipped for some trivial offense. His piercing shrieks followed each application of the lash; one of my messmates, who counted them, stated that he received three hundred and twenty-seven blows. A month afterward I examined his back, and found it still gridironed with scars.

At the Castle the negroes frequently received from five to twenty-five lashes. I saw boys not more than eight years old turned over a barrel and cowhided. One woman upward of sixty was whipped in the same manner. This negress was known as "Old Sally;" she earned a good deal of Confederate money by washing for prisoners, and spent nearly the whole of it in purchasing supplies for unfortunates who were without means. She had been confined in different prisons for nearly three years.

The next oldest inmate was a Little Dorrit of a cur, born and raised in the Castle. Notwithstanding her life-long associations, she manifested the usual canine antipathy toward negroes and tatterdemalions.

The Execution of Spencer Kellogg.

Soon after our arrival, Spencer Kellogg, of Philadelphia, one of our fellow-prisoners, was executed as a Yankee spy. He had been in the secret service of the United States, but belonged to the western navy at the time of his capture. He bore himself with great coolness and self-possession, assuring the Rebels that he was glad to die for his country. On the scaffold he did not manifest the slightest tremor. While the rope was being adjusted, he accidentally knocked off the hat of a bystander, to whom he turned and said, with great suavity: "I beg your pardon, sir."

Steadfastness of Southern Unionists.
