The sun's rays seemed to sear the earth, like heated irons, and the air that lay on the burning sand was broken by wavy lines, such as one sees indicate the radiation from a hot stove.
Except the wretched chain-gang plodding torturously back and forward on the hillside, not a soul nor an animal could be seen in motion outside the Stockade.

The hounds were panting in their kennel; the Rebel officers, half or wholly drunken with villainous sorgum whisky, were stretched at full length in the shade at headquarters; the half-caked gunners crouched under the shadow of the embankments of the forts, the guards hung limply over the Stockade in front of their little perches; the thirty thousand boys inside the Stockade, prone or supine upon the glowing sand, gasped for breath--for one draft of sweet, cool, wholesome air that did not bear on its wings the subtle seeds of rank corruption and death.

Everywhere was the prostration of discomfort--the inertia of sluggishness.
Only the sick moved; only the pain-racked cried out; only the dying struggled; only the agonies of dissolution could make life assert itself against the exhaustion of the heat.
Harvey and I, lying in the scanty shade of the trunk of a tall pine, and with hearts filled with solicitude as to the outcome of what the evening would bring us, looked out over the scene as we had done daily for long months, and remained silent for hours, until the sun, as if weary with torturing and slaying, began going down in the blazing West.

The groans of the thousands of sick around us, the shrieks of the rotting ones in the gangrene wards rang incessantly in our ears.
As the sun disappeared, and the heat abated, the suspended activity was restored.

The Master of the Hounds came out with his yelping pack, and started on his rounds; the Rebel officers aroused themselves from their siesta and went lazily about their duties; the fifer produced his cracked fife and piped forth his unvarying "Bonnie Blue Flag," as a signal for dress parade, and drums beaten by unskilled hands in the camps of the different regiments, repeated the signal.
