TABLE XVI. 



SHOWING THE LENGTH OF DRAINS IN ANY FIELD, OR QUANTITY OP 

 LAND, FROM 1 POLE TO 100 ACRES, IN STATUTE RODS OF 5 J YARDS, 

 AND IN ROODS OF 6 YARDS IN LENGTH, THE DRAINS BEING AT DIS- 

 TANCES FROM 15 TO 45 FEET APART. 



THE distance between the drains is placed on the top of the 

 page ; the quantity of land to be drained is found in the first and 

 fourth columns; and opposite any required quantity in which, 

 under their respective headings, stands the number of rods and 

 roods of drains in that quantity. 



In calculating the Table, the length of the drains in each 

 quantity is set down to the nearest quarter of a yard 



The length of drains in any piece of land may be turned into 

 local poles or roods of any given length, by multiplying the length 

 found in the Table; if in rods, by 5|, or if in roods, by G; and 

 dividing the product by the length of the given rood in yards. 



EXAMPLE. It is proposed to drain a field containing 21 acres, 

 3 roods, and 14 poles, the drains to be 36 feet apart ; what will 

 be the length of the drains in rods of 5J yards, and in roods of 

 yards ? 



Find 36 feet, the distance of the drains apart, on the top of tho 

 page,

then opposite 21 acres stands 1540 and 1411 4 

 opposite 3 roods stands 55 and 50 2J 



and opposite 14 poles stands 6 2| and 5 5| 



1601 2J and 1167 5| 



Suppose it were required to know the length of drains in the 

 above in poles or roods of 7 yards in length.
