Iosco, Leelanaw, Marquette, Manitou, Manistee, Muskegon, Osceola, Oceana, Ontonagon, Presque Isle, and School-craft, and their aggregate population in 1860 was 35,415. The same ratio which rules in the counties from which returns have been received would produce in the counties last mentioned a military strength of 4,507, making the aggregate of persons yet remaining in the State between the ages of 18 and 45, and subject to draft for military purposes, 95,578, less the number of volunteers who have enlisted since September 10, 1863." The obstacles in the way of a draft being so numerous, the War Department, with a view to enable States to raise their quotas of volunteer enlistments, left the time for drafting to the discretion of the Governors.
