The method followed hasbeen, in,the case of each fail-ure, to forward a portion ofthe rail showing the defectivecondition to the Test De-partment, with a form givinginformation regarding themanufacture and service ofthe rail. An investigationthen followed to determinethe cause of the failure. In a general way it maybe said that when failureoccurs owing [to fracture, ex-cessively^^ rapid rate of wearunder given conditions, orcrushing down in track, thepoor service is generally due to one or more of the followingcauses, viz.: (i) Pipes in the steel, (2) presence of a considerablepropor
