“ Those on active service are divided into three equal parts according to age, and the first third only is in real service, while the two others stay at home, but are bound to march out as soon as an order is given. The officers are supplied in the usual way by the military schools, in which all Cossack voiskos have their own vacancies, or are non-commissioned Cossack officers, with officers’ grades. In return for this service the Cossacks have received from the state considerable grants of land for each voisko separately. ”
