It may be well to give a few examples taken from old published 

 statements of valuation. 



Example 1. — Fourth sieve, 8 Anatdri pearls, weight 1^ manchddi, 

 market price 8 star pagodas per one chevvu. What is the value of 

 each Anatdri? 



1 T V manchddi — -f! = ff§ 

 Then, 340 

 340 



13600 

 1020 



115,600 = square of 340 

 Deduct i = 28,900 



86,700 = three-fourths of square of 340. 



86,700 



^en 320 x 320 ~ ™' which is the chevvu of these 8 pearls ; 

 and chevvu of each = ^ of this = ff 8 ^ nearly ; which at 8 star pagodas, 

 or .Rs. 28, per one chevvu, is valued at Rs. 2'2^ annas nearly. 



Where the weight is large it is shorter to postpone to the end of the 

 operation the bringing of the fractions to the denominator 320. 



Example 2. — Three pearls weigh 1 Jcalanchu and f manchddi. What 

 is the chevvu of each ? 



(83\ 2 

 j ) manchddi; 



and (f) 2= ^' three-fourths of which =^ This is the 

 chevvu of all these pearls together ; the chevvu of each one = £ 

 6889 



of this = -^j- = 107|i, or, with denominator 320, = 107|§£, the 

 chevvu required. 



Note A. — The first four " sieves " or " baskets " are called chevvup 

 peddi (2^eL©/Lj0LJi_u2), or the " chevvu baskets," from the fact that 

 in them chiefly are found the pearls of "size" and "class" good 

 enough and valuable enough to be valued by chevvu weight, and not 

 simple weight ; though this does not by any means prevent pearls of 

 the inferior classes also occurring in these four sieves. 



The next three sieves are called vadivup peddi (<su u eyuQui—iy-'), 

 or the li vadivu baskets," because the good pearls in them are called
