Most water wells in the vicinity of Butler obtain their supply from depths of 20 to 35 feet, 

 though a few of them go down 150 feet. In the northern part of the county, 6 or 8 miles north- 

 west from Butler, wells penetrate till for 60 or 80 feet before striking water-bearing gravel or sand. 

 A well 3 miles south of Hudson penetrated 75 to 80 feet of till. 



At Waterloo the drift at the gas well is as follows :

At Auburn two gas wells each penetrate about 280 feet of drift, which is largely till in its 

 tipper half and largely sand and gravel in the lower half. 



A few shallow flowing wells in the vicinity of Auburn on low ground on the border of Cedar 

 Creek obtain water from gravel below the till. The head is seldom more than 2 to 5 feet above 

 the surface. 



The gas-well boring at Garrett penetrated about 50 feet of till, 200 feet or more of sand, and 

 a thin bed of gravel at the bottom. The sand and gravel afford a large amount of water. In 

 Garrett many wells obtain water at 40 feet, but some go down 75 to 100 feet. North and west 

 from Garrett are extensive marshes with sandy borders, where wells are obtained at slight depth 

 without entering the till. 



Along the Cedar Creek valley, in the southern part of Dekalb County, water is usually 

 obtained at 30 to 40 feet. The wells penetrate more gravel than till, though both are present. 



A well 110 feet deep, in the southeastern part of the county near the village of St. Joe 

 and but a few rods from the bank of the river, is mainly through sand and gravel. 



A well on the farm of Christian Hirsh, east of St. Joseph Kiver, near Spencerville, has the 

 following section. In the same neighborhood perhaps a dozen other wells go down 60 to 

 100 feet, mainly through till.

 Whitley County. — The Columbia City gas-well boring penetrated 224 feet of drift, mainly 

 sand. A farm well on the plain in the southeastern part of the county reached a depth of 202 

 feet without striking rock. It penetrated 67 feet of clayey till, below which for 130 feet were 

 alternations of sandy gravel with beds of till. Water is from gravel at bottom. In the south- 

 eastern part of the county the wells pass through a general coating of till 50 to 60 feet thick to 

 ■strike a good supply of water; many of them are 60 to 80 feet in depth. Along the Eel Kiver 

 valley, however, there is a strip of gravel and sand in which wells obtain water at about river 

 level. 



Allen County. — In Allen County, of which Fort Wayne is the county seat, the drift is prob- 

 ably more than 200 feet thick on the northern border but decreases to about 75 feet at the southern
