putting money values on the albuminoids, oil, and 

 carbohydrates 1 respectively guaranteed in the food 

 under consideration ; but for this purpose it is 

 necessary to divide concentrated foods into two 

 groups, according to their fibre content, viz. : 



Group I. Those containing less than 12 per cent. 



fibre (except those with over 40 per cent. 



albuminoids). 

 Group II. Those containing over 12 per cent, fibre 



(including those with over 40 per cent. 



albuminoids). 



Then by allowing the following unit values 2 (which, 

 by the way, may vary from year to year), viz. : 



Albuminoids. Oil. Carbohydrates. 



I. 33. 3d. 33. 3d. is. 3d. 



II. 23. gd. 2s. 9d. is. id. 



the estimated value per ton will be obtained. 



The following examples will show how to apply 

 this method with, say, linseed cake, oatmeal, decorticated 

 cotton cake, and dried brewers' grains : 



Group I. Linseed Cake. Oatmeal. 



Albuminoids . 30 % at 3/3 = ^4 17 6 15 % at 3/3 = ^2 8 9 

 Oil . . . 10% at 3/3= 112 6 8 % at 3/3= i 6 o 



Carbohydrates 34 % at 1/3= 2 2 6 60 % at 1/3= 315 o 



Prices per ton . .^8126 . . . 7 9 9 



Group II. Decorticated Cotton Cake. Dried Grains. 



Albuminoids . 41 % at 2/9 = ^5 12 9 20 % at 2/9 = ^2 15 o 



Oil . . . 9 % at 2/9= i 4 9 7 % at 2/9= o 19 3 



Carbohydrates 26%ati/i= i 8 2 42 % at i/i = 2 5 6 



Prices per ton . . 8 5 8 . . . 5 19 9 



1 The percentage of carbohydrates is not stated on an invoice, 

 and an average analysis for the food in question will need to 

 be taken from the average analysis given on pp. 45-47.
