 alone was found Lv means of a gauge applied after the flow was under 

 control; while by a third portion of the well owners the head, or height to 

 which the water rose in the casing extended, was considered the desidera- 

 tum. It has been thought best not to attempt a reduction of these different 

 factors to a common basis of measurement, but to present the data as col- 

 lected from those who made the original observations. In the columns for 

 February, 1886, and December, 1890, the language is of these times.
