By virtue of the authority in me vested, I do hereby offer the above reward of ten thousand dollars, in gold coin of the United States, for the Arrest of Bartholomew Graham, familiarly known as Black Bart. Said Graham is accused of the murder of C. P. Gillson, late of Auburn, county of Placer, on the 14th ultimo. He is five feet ten inches and a half in height, thick set, has a mustache sprinkled with gray, grizzled hair, clear blue eyes, walks stooping, and served in the late civil war under Price and Quantrell, in the Confederate army. He may be lurking in some of the mining-camps near the foot-hills, as he was a Washoe teamster during the Comstock excitement. The above reward will be paid for him, _dead or alive_, as he possessed himself of an important secret by robbing the body of the late Gregory Summerfield. By the Governor: H. G. NICHOLSON, Secretary of State. Given at Sacramento, this the fifth day of June, 1871. Our correspondent continues: I am sorry to say that Sheriff Higgins has not been so active in the discharge of his duty as the urgency of the case required, but he is perhaps excusable on account of the criminal interference of the editor above alluded to. But I am detaining you from more important matters. Your Saturday's paper reached here at 4 o'clock, Saturday, 13th May, and, as it now appears from the evidence taken before the coroner, several persons left Auburn on the same errand, but without any previous conference. Two of these were named respectively Charles P. Gillson and Bartholomew Graham, or, as he was usually called, "Black Bart." Gillson kept a saloon at the corner of Prickly Ash Street and the Old Spring Road; and Black Bart was in the employ of Conrad & Co., keepers of the Norfolk livery stable. Gillson was a son-in-law of ex-Governor Roberts, of Iowa, and leaves a wife and two children to mourn his untimely end. As for Graham, nothing certain is known of his antecedents. It is said that he was engaged in the late robbery of Wells & Fargo's express at Grizzly Bend, and that he was an habitual gambler. Only one thing about him is certainly well known: he was a lieutenant in the Confederate army, and served under General Price and the outlaw Quantrell. He was a man originally of fine education, plausible manners and good family; but strong drink seems early in life to have overmastered him, and left him but a wreck of himself. But he was not incapable of generous, or rather, romantic, acts; for, during the burning of the Putnam House, in this town, last summer, he rescued two ladies from the flames. In so doing he scorched his left hand so seriously as to contract the tendons of two fingers, and this very scar may lead to his apprehension. There is no doubt about his
