Discussing the results, Haecker writes: ''The productive 

 capacity of the cow depends more upon type and conformation 

 than upon size or breed. Those of the beef type produced fat at 

 a cost of seventeen and a half cents per pound; tliose carrying a 

 medium amount of flesh produced fat at a cost of fifteen and one- 

 tenth cents per pound; the spaie cows lacking in depth of body 

 produced fat at a cost of fourteen and six-tenths cents per pound, 

 and the spare cows having deep bodies produced fat at a cost of 

 twelve and one-tenth cents per pound."
