Green volume specific gravity

Stamm and Loughborough (32) first reported that this relationship has been reported (32) to be approximately valid for woods of the continental United States. The mean value of the ratio Shf/G was 27 for 107 hardwood species and 26 for 52 softwood species of the United States. These ratios should be equivalent to the fiber-saturation point Mf if the green volume specific gravity Gg is taken to be... 

Solidago nemoralis is a plant which grows from Quebec to the North-West Territory, south to Florida and west to Texas and Arizona. A sample of the oil obtained from this species was examined by Schimmel Co. It was bright olive-green in colour, and had a peculiar odour, reminding somewhat of cypress oil. It bad a specific gravity 0 8799, optical rotation - 23 10, ester number 14 4, ester number after acetylation 38 2, and formed a cloudy solution in about seven or more volumes of 95 per cent, alcohol.
