THE LATE LIEUT. BARTHOLOMEW- Capt. Charles H. Watson, of Co. E., fifteenth regiment, writes to us, enclosing the following order issued to the regiment immediately after the death of Lieut. Nelson Bartholomew of his command:- Headquarters Fifteenth Regiment, Mass. Vols., Camp Foster, Poolesville, Nov. 27, 1861. Regimental Orders- In respectful memory of the high character and civil and military virtue of the late Lieut. Nelson Bartholomew, the commissioned officers of the regiment, and the non-commissioned officers and privates of Co. E, to which he was attached, will wear crape on the left arm for thirty days from the date of this order. By order of Col. Devens. RICHARD DERBY, Acting Adjt. Capt. Watson writes further, that his death has caused many a sad heart in Co. E, of which he was an active member, honored, loved, and respected, as a scholar, soldier, and officer. He was one of the first to respond to his country's call, and the honor of the early organization of the DeWitt Guards, to which his time, talent, and money, were freely devoted, was due to him. The captain, for himself and his company, tender their thanks to the kind and patriotic ladies and citizens of Oxford, who have remembered them in their absence, and acknowledges, with especial gratitude, the receipt of well filled boxes with a token of their respects.
