Imagine our feelings as we saw them approach the mouth of the hole. That tunnel, to us, was the door to liberty. It was the telescope through which we could see wife, children, and friends. Men who never prayed before, prayed now that it might not be discovered.

But alas! these prayers were vain. All our labor and our suffering in this direction had been for naught, and I am not ashamed to say that some of us wept like children over our disappointment. We did not then know by what means the enemy had discovered our plan of escape, for we could not imagine that we had been betrayed. At first we were disposed to lay the blame upon ourselves, believing that in some way the guard had discovered something suspicious from the fact that a day or two before unusual excitement had, for the following reason been manifested by those interested in the scheme.

It had been agreed between the parties engaged in digging, that while engaged in work during the daytime, we would submit to the follow regulations: Each should perform an equal amount of labor in the tunnel, and in case the authorities came into the yard, or if from any cause there should be danger of discovery, the watchman should immediately cover the mouth of the tunnel. The person digging should submit to this necessity, and take his chance for life. What that chance was, may readily be inferred, from the fact that with the mouth of the tunnel open, air of any kind was a scarce commodity, and the quality nothing to boast of.

It so happened that while I was busily engaged at work in the tunnel that day, the air was suddenly darkened, and a rattle at the mouth end notified me that the emergency had arrived, upon which we had agreed to risk life itself. I was buried alive.

To attempt to describe the sensations of a person at such a moment, is simply impossible. Within a minute from the time the mouth of the tunnel was closed, the air was exhausted. And here let me describe the manner of closing it: First, about four inches from the surface, a flange or offset received a covering of boards; over this an old shirt was spread, to prevent the dirt from sifting through the cracks, and over this about three inches of dirt were placed. Then a few whisks of the brush broom, and the eye could detect nothing to denote the existence of a cavity beneath.

It is said that necessity is the mother of invention. I was not ready to die just then; to live, I must have air. To attempt to get back to the mouth and open it, even could I succeed in doing so, would betray the existence of the tunnel, and forfeit a solemn pledge.

All this flashed through my mind with the rapidity of lightning. As by an inspiration, the means of preserving my life was suggested to me. Rolling upon my back, I commenced boring for air. Inserting the point of the hinge in the roof of the tunnel, and turning and pushing it with the energy of despair, I worked at the hard clay two feet or more above my head. Slowly but gradually, inch by inch, the improvised drill worked its way to the air and life. Just as I thought my very last energy expended, and when the handle of the drill lacked an inch of being inserted its entire length, the end broke the surface of the ground over my head, and air, blessed air, came rushing into the aperture. Withdrawing the drill I placed my mouth to the hole, and breathed. Oh, the ecstacy, the supreme comfort of that moment is indescribable! I was saved.

In the meantime, on the outside, I had a friend—not in name only, but a friend in deed—one of the noblest men the sun ever shone upon: L. G. Billings, Paymaster in the United States Navy. Billings and I were among the very few who could bear the bad air in the tunnel. He knew I was in there when the mouth was closed, and it took the united efforts of the initiated to keep him away from it. As soon as the investigating officer had left the yard, he tore open the mouth of the tunnel and plunged in.

I heard my name called, but I kept quiet, thinking I would see what he would do. Hearing no response, and believing me dead, I heard him groan, "My God, he is dead!" and then he commenced crawling to where I was. I waited until he had nearly reached me, but when I heard him sobbing like a child, I could hold out no longer.

"Billings, my friend," I said, "I am all right, thank God."
