 durability of wearing parts. 



Buckets and Tinware. All buckets should be made of 

 heavy stamped metal, heavily tinned and with all joints and

 impurities to collect. Buckets like those shown in the pre- 

 ceding chapter are desirable for milking purposes, as they 

 admit the smallest amount of dust and dirt and are still 

 simple in construction.

 moulds, workers, etc., because, by proper treatment, butter LADLE. 

 will not adhere to wood as it will to other materials.
