276 Animal Report for 1914 of the Consvlting (liemist. 



4. Barley Meal. 



5. Thirds. 



As remarked, adulteration of meals and offals is by no 

 means uncommon. The following are cases in point : — 



A B 



Barley Meal. "Thirds.'' 



Moisture 1482 



Oil 1-82 2-79 



> Albuminoids 900 10-56 



Starch, digestible fibre and woody 



fibre 70-40 



-Mineral matter .... 3-89 ()-33 



100-00 



' Containing nitrogen . . . 1*44 1-69 



^Including sand and silica . . 228 1-39 



" A " was an impure sample containing rice-husk, oats and 

 some wheat. It was not clean and contained excessive siliceous 

 matter. It cost 14s. per 12-stone sack, delivered. 



'■ B " was not genuine, either, but was much mixed with 

 palm nut husk. 



6. Pig Meal. 



The idea still prevails that anything is good enough for 

 feeding to pigs ; hence, under the name of " pig meal " are 

 found many strange mixtures. In one case that came under 

 my notice, a " pig meal " was found to consist of refuse grains 

 with a quantity of coal and coal ashes, as well as a lot of 

 common salt, the latter material being specially harmful to pigs. 



B. Fertilisers. 



1. Basic Slag. 



Speaking generally, this fertiliser has been found to be up 

 to quality, but there is, notwithstanding, constant need of 

 checking samples. The following is a case in point, the 

 material costing 41s. 3f/. per ton, delivered : — 



Per cent. 

 Total Phosphoric acid ..... 11-47 



equal to tribasic phosphate of lime . . 26-06 



Fineness of grinding ..... 86-04 



This contained only 25 per cent, of total phosphates, though 

 it had been guaranteed to have 2& per cent, phosphates that 

 were soluble in citric acid alone. The price worked out at 

 Is. 8c?. per unit of phosphate of lime (total), which is much in 

 excess of the market price.
