When the area has been measured the 

 reduction to acres, roods and perches is 

 very simple by this means. 



Suppose a rectangular plot of land, 

 whose length is 27 chains 63 links, and 

 breadth 21 chains 10 links. Then

5829930 = area in square links. 



It is only necessary to move the decimal 

 point five places to the left to bring it to 

 acres, there being 100,000 square links in 



obtain one from Messrs. Edward Stan- 

 ford, 12, 13, and 14, Long Acre, W.C. 



The rest of the outdoor equipment may 

 be made at home and should consist of : — 



1. Some straight ash poles 6 to 8 feet 

 long, with a piece of white calico nailed to 

 the top to render them more visible, and 

 pointed at the bottom for insertion in the 

 ground. 



2. Some small pegs about one foot in 

 length, pointed at one end and, say, two 

 inches square at the other. 



3. One ash pole of ten links in length, 

 each link being marked off thereon, for 

 taking offsets and called an offset pole. 

 An ordinary tape might be used instead. 



4. A note book into which to enter 

 measurements.

 decimals by 4 and 40 respectively, and we 

 get roods and perches, thus

 The answer is therefore 58ac. Ird. 7p. 



Compare this with the working required 

 if the foot chain is used and the advantage 

 is, apparent.

5. A cross staff. This instrument is for 

 setting out right angles, and may be manu- 

 factured by cutting a straight pole 5 feet 

 in length and sharpening the bottom of it 

 for insertion in the ground. On the top 

 of this pole attach firmly, so as to form a 

 small table, a piece of wood which has 

 been cut square and has two saw cuts 

 |in. deep at right angles to one another,
