Two lots of 1 6 and 18 chickens, White Wyandottes and Buff 

 Orpingtons mixed, were placed in the same class of brooder, and 

 kept on ground devoid of natural food, they were fed in exactly 

 the same manner, except that lot I had the mineral salts added to 

 the food, at seven weeks l / 4 03, and eleven weeks 3 / 4 oz per diem 

 for the entire lot, whilst lot II, had none. The following table 

 gives the comparative weights obtained in the experiments done: 



Dividing them according to breed, the results were as follows:

Use of charcoal in fattening Ducks and Geese. The Journal 

 of the Board of Agric., March, 1910. London, vol. XVI, n. 12. 

 p. 1026. 



"The Board of Agriculture and Fisheries, London have been 

 furnished by Mr. H. de Courcy with an account of some exper- 

 iments carried out by him for the purpose of deciding the exact 

 value of charcoal as a means of keeping birds that are closely 

 confined during fattening in good health. 



" Eighteen large healthy Aylesbury ducklings were selected from 

 a large flock and divided into three pens each pen containing six 

 ducklings of as uniform weight as possible. Each batch of six 

 ducklings weighed fifteen pounds, or an average of two-and-a-half 

 pounds per head. 



" Throughout the experiments the ducklings were fed upon foods 

 which previous experiments had shown to be profitable and econo-

 and tallow greaves. The method of preparing the food was to boil, 

 strain, and pound up the potatoes, which before boiling would
