WEIGHT AND MEASUREMENT 



Mr. William H. Wood, the pioneer of tarpon 

 fishing, was the originator of the formula for 

 estimating the weight of tarpon when first taken 

 from the water: 



Girth * x length 



I was puzzled for a long time trying to dis- 

 cover the reason for the divisor being 800. A 

 friendly fellow fisherman, Mr. B. R. Kittredge, 

 eventually solved the question as follows: 



"Consider in the first place that the shape 

 of the fish is represented by two wedges placed 

 base to base. The area of the base of a wedge 

 multiplied by half its length gives its cubic 

 volume. So the volume of the two wedges 

 would be the area of the base multiplied by the 

 length of one wedge. The volume of a fish 

 in cubic inches would be the area of his middle 

 section multiplied by half his length. 



If you square the circumference of any given 

 square you obtain a square that is 16 times the 

 area of the given square. For example 10 x 10
