-We aro gr.itificrl to Mato wt W. dcsse líuonanaii, lor some time connccted with this offico lias reoeived the appointment of First Lieutenant in the Sd Michigan Cavalry, now . in camp near Corinth. - Detroit Trilune. Without calling into account the fitness of the above appoiutee, we must say tliat we have loog thought that injusticc is being done in the filling of v:oancics iu our regimenté in the field by the appuintment of civilians or outsiden. - I Thcre are ocrtailily, in all the regiments which went from this State, non-commissioned officers and privates almndautlv competent to fill any eqnipany office, and when vacancies occur by resignatioii, sickness or death these worthy men are entitlcd to promotion. JJrn have gone iuto the ranks who wcre well qttalifled in every respect to receivc ;inU hold comnüssieits, and such men oaght to be selected and promotcd to the exclusión of outsiders. If the rule is once established, "once a private ahvays a private,"' goed and competent men will be coinpellcd to wait outside the ranks for commiasions, while udhering to a systcm of promotions would be au iuduecment for well qualified men to go into the ranks. Our appoiuting offieers ought to hesitate long before they send a eivili.m to hold office in a regiment iu the field.
