toured the provinces and brought instruction to the 

 farmers' doors. A description of this dairy is to be 

 found in the Spring show catalogue, 1881. 



In 1883, the Royal Dublin Society induced the 

 Commissioners of National Education to establish a 

 dairy school at the Albert Farm, Glasnevin, and 

 voted a sum of 50 to be offered in prizes. The 

 railway companies were also induced to co-operate by 

 granting free passes to pupils. The Royal Dublin 

 Society subsequently raised the vote to 100, and 

 voted ^50 to the Munster Dairy School, Cork. 

 These votes were continued for many years. In 1885, 

 Mr. J. C. Lovell, the well-known London butter mer- 

 chant, who had acted as a judge at one of the Society's 

 dairy shows, recognising the importance of the work 

 which it was doing, gave a donation of 100 in aid 

 of dairy industries. 



Meantime a momentous change in dairy methods 

 was in progress. For some years attempts had been 

 made to devise a machine that would separate cream 

 from milk by centrifugal force. The problem was at 

 last solved by Lafeldt, a German civil engineer, in 

 Schoningen, Brunswick. Mr. Milward, in the report 

 above referred to, mentions a visit to the works of 

 the Centrifuge Company at Hamburg, where he saw 

 the Lafeldt separator at work, and recognised the 

 importance of the invention for butter-making in fac- 

 tories. At the same works he saw the Laval separator, 

 and remarks that if it is to work at 6000 revolutions 

 a minute, he would rather not place it in the hands of 

 his dairymaid. The centrifugal cream separator under- 

 went rapid development, and revolutionised butter- 

 making in the same way that the Arkwright spinning 

 frame and Cartwright power loom had revolutionised 

 the textile industries in the latter part of the eighteenth
