The medical officers of the Eighth were at all times zealous and efficient in instructing officers how to combat disease, and the regimental officers were intelligent and active in carrying out these instructions.

Before typhoid became epidemic, Colonel Pew assembled officers and men after evening parade, and explained to them the nature and cause of this fever. He said this disease had already broken out, and he anticipated it would become a scourge to the troops, because of the unsanitary condition of the various camps. That it was caused by microscopic germs found in the discharges of the sick. That these germs were very tenacious of life, and increased and multiplied rapidly in filth. That when dry they would drift about in the air and lodge on food, clothing or the person. That they were harmless unless taken into the mouth, but as they were too small to be seen, there was always danger of contagion. That they were killed by boiling, and for that reason the men would be required to drink only boiled water, and keep their food protected against dust. That all human excreta must be deposited in the proper place, and covered with a paddle, as Moses taught the children of Israel to care for themselves in the Wilderness. That police regulations would be enforced, and camp conditions made as unfavorable as possible for the growth and development of these germs. He urged the men to appreciate the danger to which they were exposed, and to avoid it by complying strictly with all sanitary regulations.

The Medical Board appointed to examine into the causes of the existence and spread of typhoid in the national camp of 1898, reported that this fever was brought to Camp Thomas by the volunteers, and spread by the neglect of the rules of sanitation and military hygiene. Out of forty-eight regiments whose medical records were examined, nine regiments reached Chickamauga with developed cases of typhoid, twenty-five regiments developed cases within two weeks, and at the expiration of one month only two regiments of the forty-eight were free from this disease. The first case of typhoid in the Eighth Regiment was reported July 13.

The average volunteer at Chickamauga had little discipline, and a slight knowledge of sanitation. He was willing to fight, as he had enlisted for that purpose, but he rather resented as an invasion of personal rights, any attempt to dictate what he should eat or drink. He did not accept in full faith the germ theory of disease, and was skeptical about the existence of bugs he could not see.

If water looked clear and was cool, he was unwilling to believe it was unwholesome, especially when it tasted sweet and satisfied his cravings. He was willing to believe that any water in which fish could swim, was good to drink, or to accept any other absurd test which was current.

The experience of an outpost from the regiment illustrates the chances intelligent college men would take, when it became a question of satisfying the appetite. This outpost was established on the banks of Chickamauga Creek, below the inflow of camp sewerage, and obtained their drinking water from a spring bubbling up in the slope of the bank. A sudden rain caused the creek to rise and submerge the spring. After the water subsided, the outpost discovered the surface of the spring covered with slime.

Someone suggested bad germs floated, and acting upon this theory, they plunged a canteen to the bottom of the spring, with the opening stopped by the thumb against the entrance of bacteria. When the canteen was on the bottom, the thumb was removed until the canteen was filled, the opening was then again plugged with the thumb, and the supply brought to the surface. Every member of this outpost was stricken with typhoid as a result of this experiment.

Although orders had been issued to drink only boiled water, most men in the corps drank what they pleased. Unsatisfactory rations led many men to patronize the various food venders. Near the railroad station a swarm of booths sprung up, where all kinds of food were dispensed. These stands were not subject to medical inspection, and later were denounced by the Medical Department as sources of contagion.

The chief sources of contagion were company sinks. Digging and caring for sinks did not appeal to the men as heroic soldiering. They hated and shirked this duty and as a result the sinks of many regiments were so repulsive that the men refused to use them, and polluted territory surrounding the camp.

The care of the sinks was always a matter of great solicitude to the officers of the Eighth. Their cleanliness was insisted upon at all times with martinet rigidity, and men were punished for not using them, after the formality of a trial and conviction before a summary court.
