In Germany, for taxation purposes, one solid cubic meter of 

 wood is reckoned at 600 kilos, (a cubic meter = 35'1 cubic 

 feet, and 1 kilo. = 2"2 Ibs.). In German railway-transport a 

 cubic meter of hardwood is considered to weigh 1,000 kilos, 

 and of softwood, 750 kilos. 



The following list of the air-dry and forest-dry sp. weights 

 of wood has been prepared from data supplied by Nordlinger, 

 Chevandier, v. Baur, Biihler, Karrnarch, v. Exner, v. Secken- 

 dorf, Moller, Hartig, Mohr, Sargent, Fernow, Schw 7 appach, as 

 well as by the authors of the present book. It is well known 

 that good average figures may differ from the actual weights 

 when the maximum and minimum weights of the same species 

 also differ considerably ; this is especially the case in forest- 

 dry wood, where incorrectness depends more on the amount of 

 napwood and heartwood in the specimen than on the water it
