The following is an extract from a letter written by an officer of the 36th Regiment, to the editor of the Berlin Advertiser: --

Capt. G. S. Hastings, of Berlin, is in a hospital at Mound City, Ill., very sick, but I believe with some prospect of recovery.

The 2d lieutenant of my company, F. H. Sibley, died at Louisville, the 17th ult., of malignant dysentery. My cook and private servant are in a hospital at Cincinnati. I sit alone and muse on the ravages of war, o'er the uncertainty of human life. I regret to announce the death of Geo. H. Mondell, of Feltonville. He died upon the transport Dakotah, a few miles from Memphis. He has served many months in the Ambulance Corps. He was faithful, efficient and brave. He volunteered to go outside our lines at Jackson to bring in one of our wounded men after two had been wounded in the attempt. He brought the man in, although the poor fellow had died.

Although a stranger to you, Lieut. Sibley deserves more than a passing notice. I was intimately associated with him and knew him well. He was formerly in the 15th Massachusetts regiment, and had been -- I think -- in ten general engagements and skirmishes. He was one of the finest men I ever knew. An accomplished soldier, a true patriot, an honorable and upright man. His gentlemanly deportment had won for him the esteem of all who had the pleasure of his acquaintance.

"There is a tear for all who fall;
A mourner o'er the humblest grave,
But the nations swell the funeral cry,
Where death has triumphed o'er the grave."
