tions. With that exception, the accompanying map of the county is 

 largely conjectural. 



A short distance ahove Florida is the quarry of Wesley King and 

 brother, in the left bank of the Maumee. It consists of the following 

 succession of parts : 



No. 1. Compact, blue limestone, the same as at Dilz's quarry, in 

 Defiance county ; very hard, showing few fossils, none 

 of which are distinct. "It contains considerable pyrites 



and calcite, and some chert 1 ft 2 in. 



" 2. Porous bluish or gray stone ; fossils indistinct from crys- 

 tallization and absorption ; stone crystalline and hard, 

 somewhat resembling the Niagara ; crinoidal joints and 

 Cyathophylloids, including a Cystiphyllum, can be iden- 

 tified. Exposed 2 "

v These beds lie nearly horizontal, but dip slightly into the river south- 

 east, east, and north-east. Fifteen rods further down the black slate is 

 found in the river, making it impossible for more than two feet of shale 

 (the representative of the Olentangy shale of Delaware county) to inter- 

 vene between this stone and the overlying black slate. 



At Florida there is a stratum of thick-bedded black limestone within 

 the black slate, though near its base. It is exactly the same, in all out- 

 ward aspects, as a heavy-bedded black limestone seen in the black slate 

 in the northern portion of the lower peninsula of Michigan, outcropping 

 at Sulphur Island, in Thunder Bay, and at Sunken Lake, in Presque Isle 

 county. At Florida it is used for all common purposes by the country 

 people, and has been burned into lime. Below this place the Maumee is 

 filled with the slack-water from the Providence dam, constructed for 

 canal purposes, and no other view of the bed-rock can be had. At Na- 

 poleon, however, a well was drilled by Mr. H. T. Osborn, in 1872, 

 which, according to his record, struck a gray limestorie, after passing 

 through the Drift, at the depth of forty-five feet. It had a thickness of 

 about thirty feet. The well was continued to the depth of seven hun- 

 dred and fifty feet. Water was obtained at seventy feet, and again at 

 ninety feet. Another well was drilled at Texas to the depth of one 

 thousand one hundred and eighty feet, which furnished strongly sulphur- 

 ous water from the depth of four hundred and fifty- two feet. The rocks 

 passed through here are said to be the same as at Napoleon, but the 

 records at both places are not reliable for geological purposes. The black 

 slate was struck at one hundred and fifty-seven feet at Wauseon, in Ful- 

 ton county. Water was thrown out, with gravel-stones, to the height of 

 nearly one hundred feet above the earth, by a powerful escape of gas.
