J J Greenwood mentions that in the measurement of New Forest cordwood, " 60 cu ft of timber weighs about
one and half tons depending on the species and moisture content", i.e. about 40 cu ft per ton.
This reminds me that when my wife and I sailed to India in 1957 for me to take up my job with Indian Copper Corporation
(pace Peter, got to get mining history mentioned in this somehow!), our ticket for the three-week voyage (I was to be
junior staff, and only seniors went by plane) we were allowed "one ton" of luggage to be stored in the ship's hold,
the definition of this being that "one ton" meant 40 cubic feet! I guess this is about right for the density of sea water.
Sorrry to quibble, but I think Roger has got his sums wrong when he says a cubic yard in 9 cubis feet. I think
he means 3 x 3 x3 = 27 cubic feet.
