In order to gain first-hand experience of the conditions encountered by the growing number of vessels plying the Hudson Bay route, Mr. R. E. Perry, an engineer of the Decca Radar Company recently made a passage to Port Churchill in the S.S. North Anglia.
During the course of this passage a complete radar log was kept by Mr. Perry. This log is noteworthy not only for the many reports of the radar detection of various types of ice but also for the detail and completeness of the information recorded.
