Report on the laboratory examination of the effect of fungal invasion on the durability of untreated mine support timbers

Abstract

The technique developed on the laboratory for assessing the progress of decay in individual test poles 3 ft. in length and 5 ins. in diameter by the periodic measurement of their resistance to bending, has been further applied to an examination of the durability of untreated mine support timbers subjected to the invasive action of fungi under warm humid conditions.
