"(1) Chicks appeared to need both cracked and ground food. (2) Chicks 

 grew more rapidly on moistened mash than on dry mash, other conditoins be- 

 ing equal. (3) Chicks fed from the first on dry mash and grain were nearly 

 as large at the end of 8 weeks as those that had been started on a moist mash 

 and later changed to dry mash. (4) Skim milk mash produced growth on less 

 food per pound gain in weight than did dry mash. (5) Chicks that were 

 given hopper-fed beef scrap from the first, in connection with cracked grain 

 and ground food, made better growth than those started on a limited amount 

 of beef scrap. (6) Chicks given a limited amount of beef scrap for the first 3 

 weeks grew better than those whose meat food was given in the form of eggs. 

 (7) No ill effect was observed when beef scrap was hopper-fed from the first 

 meal, if given in connection with a well-balanced ration. (S) When the other 

 food given did not supply their needs, chicks ate sufficient beef scrap to cause 

 high mortality from digestive ailments. (9) Sour skim milk proved of value 

 for chick-feeding. (10) Sour skim milk fed in a moistened mash gave better 

 results than granulated milk fed under the same circumstauces."

 fattening period which followed are summarized in the table given below :

The experiments as a whole indicated that the feeding of both cracked and 

 ^ound grain was more desirable than the feeding of eitfter alone. For the
