Evening Republican, Volume 21, Number 165, Rensselaer, Jasper County, 23 July 1918 — Use for Hemlock Bark. [ARTICLE]

Use for Hemlock Bark.

Spent hemlock bark, which has been used chiefly for fuel, may soon be important In felt manufacture. Experiments have shown that this bark can be substituted for 30 per cent of the basic material, now chiefly rag stock, used in roofing felts. If the bark is used for the 200,000 tons of felt made In this country anhually, there will be a saving, It Is thought, of about $1,000,000 a year.
