AUGLAIZE COUNTY. 407 



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 Tymochtee 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 generally 

 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
