 Oke also weighed in on building materials, such as firmly advising against the continued use of lower-cost iron towers as not suitable for Newfoundland, citing the example of Cape Race Lighthouse in 1856 whose living quarters he deemed uninhabitable due to condensation and hoarfrost.A Canadian engineer, G. F. Baillarge, visiting 10 y later, supported Oke's assessment.Oke routinely assessed the mariner's need for alterations in lighting patterns, making adjustments in the number of reflectors and lamps or the sequencing of the light apparatus.
