AUGLAIZE COUNTY. AOT 
Auglaize River, section 22, township of Logan. It is worked for founda- 
tions and for walls, as well as for flagging; and being the only stone ob- 
tainable within a radius of many miles, particularly toward the south, 
east, or west, it obtains an extensive sale. The Dayton stone is, however, 
principally used for heavy walls and for abutments in all the western 
portion of the county. The most important opening in the Waterlime 
is that of Mr. George Lathrop, although it is also quarried by Mr. Rus- 
sell Berryman, Mr. J. Pierson, and Mr. Benjamin Backus. The stone is 
generally thin-bedded and blue, with much bituminous matter, present- 
ing the features of the T’ymochtee slate. It is usually not well adapted to 
lime-burning, although some of the beds, particularly those which are 
thicker and irregular, or vesicular, could be profitably employed in that 
way. 
The Drift.—The composition of this deposit in Auglaize county is not 
noticeably different from that already described in giving the geology 
of adjoining counties; yet the proportions of its constituent parts seem 
to undergo a gradual change toward the south. The clayey element is 
more frequently replaced by assorted sand and gravel. These materials 
seem to be embraced within the clayey hard-pan, and to be developed 
upward through it, from the gravel and sand bed which often lies on 
the rock, and which even in the Black Swamp forms the lowest part of 
the Drift deposit. They are, however, undoubtedly disseminated in de- 
tached beds, or pockets, through the whole thickness of the Drift. In the 
ridges which have been mentioned as crossing the county these coarse 
materials greatly predominate, always showing an arrangement in beds, . 
and exhibiting most perfectly the oblique stratification which in a for- 
mer chapter has been attributed to the effect of streams of water issuing 
from the melting ice of the glacier. Yet even here these beds are almost 
every where buried beneath a greater or less thickness of unassorted 
Drift, which has every appearance of that which covers them eenerally 
throughout the country, and which every where forms the soil, unless 
it has become covered with subsequent alluvium. Where the action of 
the glacial streams was intensified by the geological conformation of the 
surface, or by the occurrence of canons or crevasses in the ice, or was 
prolonged at a single point, this stratification and assortment of the 
Drift would be best developed. Such seems to have been the case in 
the vicinity of St. John’s. Bowlders are not common in the county. 
They are usually altogether wanting in the level or gently undulating 
tracts lying between the ridges; but in the vicinity of the ridges, and 
on them, especially in the drainage valleys which sometimes intersect 
‘them, they are very often seen. Although the greater part of them are
