Attention! Heavy artillery : The finest opportunity offered for enlistment Battery L Third Penna. Vols. Colonel Segebarth. This reg't offers extra facilities and unusual opportunities: 1st. It avoids long and fatiguing marches, being solely confined to forts, fortifications and entrenchments. 2d. It will be under Gen. Sigel, which is sufficient guarantee for its success. 3rd. The life of an artillerist is healthier. 4th. A recruit becomes sooner perfected in all the duties of a soldier. These with other reasons combined, makes this regiment a most desirable one. It is in full course of recruiting. Recruits will be sent at once to camp, with clothing, camp and garrison equipage, with medical attendance, and under experienced officers. / Capt. Jos. W.
