tract price for each per cent of ammonia or ^^y, J^ or Jg of the con- 

 tent of protein and fat as the case may be and proportionately for 

 the fractions of the deficiency in ammonia. 



Section 5. No claim for deficiency of protein and fat combined

If a lot of cottonseed meal is guaranteed to test 41 



Method of per cent of protein (8 per cent of ammonia) and 



Calculation, only tests 35 50 per cent (6.9 per cent of ammonia), 



it shows a deficit of i.i per cent ammonia. If the 



contract price was $28 a ton, according to the above rule yL of the 



price would be ^2.80, and j\ of that .28 which added to the $2.80 



would be $3.08, which is to be deducted from the $28 in the form 



of rebate.

In order to secure a representative analysis of any 



Methods of lot of feed, it is necessary that a correct sample 



Sampling. be taken. Different bags of cottonseed meal have 



been found to vary noticeably in their content of 



nitrogen or protein and a sample taken from a single bag or from a 



few bags would by no means be representative of a car lot. 



Rule J 4 of the Cotton Crushers'' Association : Two ounces or more 

 from each sack shall constitute a sample of meal and must be drawn
