Water was first struck between 35 and 40. More than ten "crevices " 

 [probably water cracks] passed between 35 and 100. The water now 

 rises to within 16 feet of surface. Steam pump delivers 1500 gallons per 

 hour. After ten hours' pumping the water falls only 10 feet in well, the 

 whole fall occurring, however, in the first 45 minutes. With an un- 

 proved pump 3000 gallons per hour were obtained.
