constitute about one-third by weight of the mash. Barley meal 

 and ground oats were then mixed in equal parts and mixed with 

 the potatoes. Skim milk was added to form a rather wet mash. 

 This was fed to the ducklings from the end of the fifth to the

 day to each duck. Grit and water for drinking were liberally 

 supplied. Apart from the charcoal the food received by all the 

 ducklings was the same. 



"Pen No. i was allowed no charcoal, Pen No. 2 was given an

" The experiments with geese were conducted on similar lines 

 and gave almost identical results, as shown in the following table. 

 The breed was the Embden-Toulouse. The foods fed to the geese 

 were the same as those fed to the ducks, except that they got
