PREFACE. 



THIS work consists of Tables, so constructed as tc 

 give the content of any regular piece of land, measuring 

 from one yard in length and breadth, to five hundred, 

 by the addition of not more than three sums. And 

 should the length or breadth exceed five hundred yards, 

 its content may readily be found, by observing the rules 

 which will be given in the course of the work. And to 

 render the book as useful as possible, the preference is 

 given to the use of yards, rather than to rods, or chains 

 and links : as all farmers can tell the length and breadth 

 of a piece of land by pacing or stepping it ; therefore, in 

 most cases, the content of a field might thus be. known, 

 without using rod or chain, sufficiently exact for paying 

 labourers' wages; ascertaining the quantity of land 

 ploughed in any given time ; manuring, or apportioning 

 seed at the time of sowing, as well as for harvesting 

 the crops ; without the necessity of employing a person 

 to survey and measure thus settling trifling disputes 

 between masters and workmen, to the satisfaction of 

 both, without calling in the aid of a third party. 



There is added a table, which shows at one view what 

 width is necessary to form a square of land of one acre,
