12 At start rose 50' above the surface, stopped flowing in 1887, and not used for 1 year; pump then put in. Water 

 at present 20' below surface; water very soft. 



13 Trouble supposed due partly to the nature of the 600' sandstone and partly to poor construction. 



"Mowed full for 4 months after sinking and then diminished; water now 20' below surface. Has been pumped. 



15 Decrease supposed due to the sinking of other wells. 



M Decrease directly due to the sinking of other wells. 



17 At start flowed 20' above surface; at present 20' below. 



l *Flowed 18 mouths; water at present 27' below surface. 



19 Decrease supposed to be due to a tilling up with sand. 



• n Plowed but a very snort rim.-; now 12' below surface. 



21 At start rose 73' above surf;nr ; ;t l present very far below. Uses a 200' plunger; at one time threw up consider- 

 able mud and sand ; not clear now. 



-■' At start 75' above surface; now 50' below. 



23 At start water rose 75' above surface, but when well at Burlingtpn shops was sunk fell gradually, and at present 

 is 25 below surface. Only lower flow used in 188 t.
