8 TABLE I. LAND MEASURING. 



on the right hand there are 4T yards, 12 feet = 48 yards, 3 feet; 

 and as 30 yards, or 30 yards, 2J feet, make a pole, that quan- 

 tity is subtracted from 48 yards, 3 feet, leaving a remainder of 

 18 yards, Of foot, and 1 to carry to the next column, making 50 

 poles, subtracting 40 from which, set down 10, and carry 1 to the 

 next column, making 5 roods, from which subtract 4, the roods 

 in an acre, set down 1, and carry 1 to the column of acres, which 

 makes 59, as above. 



On inspecting the Table, it will be observed that the feet column 

 consists almost exclusively of the figures 2, 4, 6, and cyphers: 

 these may be understood to be 2J, 4|, and 6|, which are equal to 

 J, J, and | yard; and, in an addition such as the foregoing, it 

 would facilitate the operation were they so set down, as in the 

 following example: 



3. Required the content of a field 480 yards, 2 feet, 6 ii dies, 

 in length, and 228 yards in breadth? 



Find 228 yards, the breadth, on the top of page 86, and 

 divide the length into portions of 400 yards, 80 yards, 2 feet, 

 and 6 inches; then,

In the column of yards there are 64 J, from which subtract 

 twice 30J, or 60J = 2 poles, set down the remainder 4, and 

 carry 2 to the next column, making 24 poles, which set down, 

 there being nothing to carry as it is less than a rood, the next 

 column contains 6 roods, set down 2, and carry 1 to the acres, 

 making 22 acres, as above.
