 It is stated in the article alluded to, that "in the common method 

 of computing the area of a field, a meridian line is supposed to be 

 drawn at some assumed distance from the commencing corner." 

 This it is imagined is incorrect. The most "common mode," is to 

 select for the point of commencement, the extreme East or West 

 station of the field. Through this station, the first meridian is made 

 to pass, and the necessity of an " assumed distance" is thereby avoid-
