Clean Milk


THE importance of clean milk, by which is meant a milk free from visible dirt and having a low bacterial content, has been recognised for many years, and various attempts have been made to improve the general milk supply. To a large extent these have failed owing to the conditions which have been supposed to be necessary to attain this end, involving considerable expenditure in reconstruction of buildings and extensive modifications in methods and plant—alterations which, setting aside cost, it is difficult to induce the average farmer and dairyman to adopt.
