A LTHOUGH in this country the closing years of the 

 IV nineteenth and the beginning of the present century 

 have been marked by great progress in the dairy industry, 

 we are still far behind Denmark, a country with an area 

 similar to the province of Munster, which, under exceedingly 

 unpromising conditions has become an object-lesson in agri- 

 cultural organisation and butter production, to the whole world. 

 The world's surplus butter and cheese supply finds a free and 

 ready market in Great Britain. Our Colonies send one-

 consume, but great progress has been made in the United
