oyster shell 1, the nutritive ratio of this 1 :64. In order to get 

 some term to show the proportion of organic and inorganic phos- 

 phorus, we will call this ratio the phosphorus ratio, the ratio in 

 the feed called the organic feed is 1 :17. The inorganic phosphorus 

 feed, which is made up of corn 1, oats 1, wheat (treated) 1, bone 

 meal 1. The nutritive ratio is 7 :5.6, while the phosphorus ratio 

 is 1 :30. It will be seen that there is a wide varying ratio between 

 the two forms of feeding stuffs. The wheat termed "treated wheat" 

 was treated as follows : 



The whole wheat soaked for twenty-four hours in water at ordi- 

 nary temperature, as there seems to be no difference as to the 

 amount of organic phosphorus taken from the wheat when treated 

 hot and cold water. The wheat after this treatment is drained for 

 half an hour and fed to the chickens, or a large amount treated in 

 this manner, thoroughly dried and kept for further feeding. This 

 treatment removes some of the organic phosphorus in the form of 

 riiytin. The amount removed is comparatively small as may be 

 seen in Table A.

The condition of the chickens before the ration feeding was 

 normal; they were laying well considering that they were in small 

 pens, also housed. The chickens were fed on a uniform feed I'm 1 

 several weeks before changing to the organic and inorganic rations 

 in order to get them on a uniform basis. 



The temperature at which tlu> eggs must be dried \vas found to be 

 a mot important factor'- when it comes to the determination of the
