 There are too few agricultural text 

 books by Canadian authors. The average 

 professional worker, whether he is a col- 

 lege instructor or an extension worker, or 

 both, has always been, dependent upon 

 certain "standard" volumes for reference 

 purposes. In most instances these same 

 Canadian workers have developed ideas of 

 their own, have done original work and 

 have, on the public platform, proved that

 mal diseases. An interesting ^ feature of 

 the volume is that it includes a market 

 classification and a gestation table. There 

 are also chapters on the judging of live 

 stock, on stock feeds and theii- uses and on 

 breeding problems.
