The Post Office. — The first attempt at supplying the inhabitants of Montfort and the surrounding country with mail facilities was during the year 1828, or thereabouts, when Daniel Durnell carried the mail from Mineral Point to Blue River, the post office at the latter point being Centerville.

"The valley now occupied by the river, from Mazomanie to Blue River, is very nearly that of the present line of strike of the Lower Silurian formation, and, although from there the strike of the lower members (of which outliers still remain) appears to bear rather more to the northward, yet observations on the dip of the Cincinnati group, in such occasional outliers as remain, lead us to believe that its original strike was approximately in a southwesterly direction, from Blue River to the Mississippi.
