<br />Auger hole was filled with water to the ground surface to prevent
<br />the sides from sluffing during excavation. Some sluffing occurred.
<br />Water level encountered at 10.0 feet. After a 30 minute time lapse
<br />the water had risen to 7.8 feet. and remained at that level. Auger
<br />hole \\Ias cased from 0,0 to 12.0 feet with 24"inch casing to prevent
<br />sides ''-If augel~ hole from caving during remainder of excavation.
<br />Cobbles encountered at 11.5 feet causing increased difficulty in
