From The Michigan Twelfth

1-th Regiment Michigan lN].snv, Prktiss' B::k;.te, ) ' MM I'S 80UTB OF PmaBUROII, TBHX. , Apvil 4 Ui, 16C2. j Mr. Editor : - In my lasL I made n'siight inistake in the statement of our position. I was niormed on tho boat that our place of landing was in Alabama. Pitteburg landing is about threo miles from the state line. It is merely a landing-, not a villnge as you might suppose, thoiigh the shoro is lined . with stearners sufficient for a large town. It was taken from the rebels about ton days before we carne. I slept on the battle ground the first night I spont in Dixie ; ar.d during the evening I listened with intense interest to the tules of sorae of the Donelson soldiers, wbo carao to sit and talk at our waleh fires. We seem to ! have entcred a etrange land of poetry wheie héroes are all around us; telling of the foats of valor they havo witnessed. . ( A few days aiter wo pitclieu our ' tents I wanderod over u part. of this immense camping gvoiind, in seareh of ; a regiment. A battallion hero seems like an insignificant body of men, and ' a Colonel becomes quito commen ' personage. On the battlo field a private even may stand forth from the ' vast host, one of nature 's noblemen ; but here in camp he is completely ab. sorbed. He has no indivuduality, and is a mere wheel-cog ia the resistless I rnachicery whioh is crushing everything : before it. This may be a üttle ' ing on the spirits of those who are ' ardent for war, and so it should bfi ' If yonr country calis, go, but a rior'a lile n not one fitted for civilized ' men. Thisisatruth which some ' Jiers whose patriotism ís only skin-doep ' wish they knew before. ; Evory thing with us is in a state of ] waiting and ju'eparation. How many ' men e have, it ould hardly bu proper ' to state, even' if I knew. It wil] be '■ sufficient to say that we have a forcé ready to meet any anny the rebels can '■ bring against us. New regimenté ■ arrive daily, and clear up tboir own camp in the woods. "Ten men from each company," without oxen, are ] equal to any logging bee ever seen m Michigan. Beauregard's army at ( Corinth, Miss., 18 rniloa soutii, is reported at all figures from 30,000 to 200,000, bat doubtless does not exceed 100,000. If we have a battle, and we may any day, it will be the grentcst in point of numbers and irnportanee ever fought on the American Continent. It is reported that Jefi. wishes to settle, very wel!, it i time; but it must be a very reasonabla proposition ou his part wboh will disband theUcion army. On Tnesday three of our gun boats shelled out a rebel station loma miles up tbe river and returned without any damage, the secesh having only struck one of the sinoke stacka. The uext day our scouts captured a spy and picket. They were true to their treason as may be espected, and would reveal nolhing of all their store of knowledge. Today we sant out our first pickets, and are preparad for details oí numerous exploits on the morrow. üf the two great southern institutions, cotton and slavery, we havo seen very little. The Twelfth drill in a field with corn stalk down the centre, green wheat on ono sido and last year's unpicked ootton stalks on tho other. - The great plant looks very much lite a thickly brunching hazel bush with dried hickory mits at the joints. We saw eeveral slave huta on the livor banks as we camo up, and stoppod at one landing where slave was sol e m aster. He acted decidedly friendly, and performed a very acceptablo service to the officers by selling theta straw hats at a dimo apioce. Tho whole country along the river is almoat dopopulatcd, some seeking Unioa, eomo secossion frionds, and all safoty. Tvvico beforo we arrived at Savannah We stoppod to tako Union. men on board. This región, though warm, is one of tho henlthiest of the tíouth ; the changa of climate, however, has affectcd sevcral of the men. We will soon be all right, ready for the battie which I may toll you of in my next.
