Heating Plant, Old and New, at Preston Mines, Limited

CIM Bulletin, 1962


I T IS one of the unwritten policies at Preston Mines that we examine .closely any method or tool that will help us in our constant battle against rising costs. It is our personal conviction that most work methods can be improved. Therefore, even though the job went well yesterday, it does not necessarily follow that it should be done by the same method today.
