Iuka is a pretty little town twenty-five miles east of Jacinto, Mississippi, and is on the Memphis, and Charleston railroad. It is twenty miles south-east of Corinth, and is pleasantly located. The country is rather better than any we have seen in Mississippi, and the improvements are good. The town has some very fine buildings, for private residences, and one fine large hotel. It has several mineral springs in the neighborhood, which have obtained quite a notoriety for their curative properties. Iron, sulphur and salts, characterize the water of these springs. The chalybeate spring is highly impregnated with the medical properties of iron, and is no doubt admirably adapted to some cases of disease. The sulphur spring is also strongly tinctured with sulphur. On account of these springs, Iuka has been a favorite resort for invalid planters and their families, and perhaps, some day may become a noted "watering place."

The regiment went into camp half a mile south of town, on a pleasant piece of ground, formerly used as a play ground for the scholars of an academy located there. The academy building was yet standing, but had been used as barracks for soldiers, and was very much abused. Doctor Maynard took possession of it now, for the use of the sick.

The regiment had now marched in its advances and retreats, over two hundred miles since coming to the State of Mississippi, and the men were willing to rest for a short time at Iuka.

Rumor now has it, that one Brigade is to remain here during the balance of the summer. The men are thereby encouraged to erect some more pleasant bowers, to protect themselves from the excessive heat.

A day or two after coming here, two of our boys, while scouting through the country, stopped at a widow womans, and in genuine guerrilla fashion, proceeded to rob her of all the money she had, some forty or fifty dollars. The woman followed them to camp, and reported the affair to the Captain of the company. The boys were arrested, but what punishment they received, deponent saith not.

Two other cases of a similar character, only on a much larger scale, and perhaps with more justice, occurred while laying here. A rich old planter, living about two miles from town, had the reputation of being a rebel, although he remained at home, and apparently minded his own business. General Mitchell, however, supposed him to be a fit subject for arrest, and to have the law of confiscation applied to his property. He, therefore, sent a squad of men, and brought the old man to town, together with horses, mules, wagons, cotton, and negroes, to the amount of twenty thousand dollars. All the property was taken for the benefit of the Government, and the old gentleman was held for the safety of the commonwealth.

The other case was that of an old planter in Alabama, about twenty miles south of Iuka. He, too, was rich, with negroes, cotton, mules, etc., and was tainted with disunion sentiments. General Mitchell deemed it necessary to clip the wings of his riches, also, lest they should fly over to the rebel cause. Accordingly, a detachment of two or three regiments, the Fifty-Ninth included, were started out one evening, about sun-down, to make him a visit. After marching all night, they came to the plantation at sun-rise, or just before, but not early enough to catch the old planter. The negroes, cotton, mules, horses and wagons, were taken in possession. Other plantations were visited, and many bales of cotton were found hid away in the brush, the hiding places being pointed out by the negroes. The expedition returned, with ninety bales of cotton, besides other property, to the amount of several thousands of dollars. These three cases were somewhat similar, but with this difference: the one was in accordance with guerrilla warfare, the other according to the law of civilized warfare.

The health of the regiment continued good while here, although some cases occurred from the excessive use of green corn, and other imprudent indulgences. One patient, (Nathan Logue, of Company B,) was taken sick on the morning of the 18th, was sent to town to general hospital on the morning of the 19th, and died that afternoon, at three o'clock.

The First Lieutenant of Company F, (John Kelly,) was here compelled to leave his company, and attend solely to his own afflictions. For several months his eyes had been affected with severe inflammation, which now became almost insupportable. The Surgeon, (Doctor Maynard,) had frequently advised him to resign his commission, and leave the army, until he could get his eyes restored to a healthy condition. This he persistently refused to do. His love of country was above all considerations of self. Said he: "My country needs my services. I was, also, instrumental in getting the boys of Company F to enlist, and they were generous enough to give me the second position in the company, and now I will not desert them. I will share their toils and hardships as long as it is possible for me to do so." Now his eyes had become so much inflamed that he could not see. The pain was excessive, his whole system became deranged, fever set in, typhoid symptoms soon made their appearance, and he became prostrated. He was taken to a private house in town, was well nursed and medically attended; but nature could endure no longer, and, in August he was buried at Iuka, Mississippi. He was beloved by all belonging to his company, and highly respected by every officer and private in the regiment. His love of country was only excelled by his love of virtue.
