thereto. In some cases, it was impossible, on account of the end of the mile 

 coming in water or on unsuitable ground, to plant standard iron posts and dig 

 pits and erect mounds. In each of such cases, a standard iron post, surrounded 

 by a witness trench and accompanied by a conical mound, was planted at the 

 nearest even chain where suitable ground could be found, from the correct 

 position of the point to be established. These witness posts, trenches and 

 mounds were planted to indicate the following points: 



On first base line, 9 mile and 18 mile. 



Preparing niouiuls ; lul pits. 



On first meridian line, III mile. 



On second meridian line, III mile. 

 Frequent observations were taken to determine the bearings of the lines 

 run. The greatest variation from the theoretical bearing, found in the survey 

 of the lines, was 2 minutes. The bearing of the first meridian line is north 

 degrees 2 minutes east, astronomically. This was discovered after the line 

 was run nearlyj^^all the way through, and it was continued to the end on this 

 bearing.
