After a passing reference to the increasing usage in Russia of reeds tied in bundles as material for filling in constructional interspaces, the author states that in controlled experiments such bundles were readily and completely rotted by Merulius lacrymans and Coniophora cerebella at high relative humidities of the environmental air. Soaking the bundles in a 1 or 3 per cent. solution of triolith (the composition of which is stated to be 0.17 per cent. insoluble matter, 1.93 per cent. moisture, 5.12 per cent. chromium calculated as sodium dichromate, 76.86 per cent. sodium fluoride, and 15.93 per cent. organic and other substances), or in 5 per cent. zinc chloride, effectively preserved them from decay, even under optimum conditions for the development of the fungi, but copper sulfate solutions at concentrations as high as 10 per cent. were only partially effective.
