UTILIZATION, MARKET, AND TECHNOLOGY 



Wood preservation practically ceased in Ger- 



JVar and many during the war on account of the difficulty 



Wood of securing preservatives. Creosote and cor- 



Prcservation rosive sublimate were both commandeered by 



the Army, the former for fuel and the latter for 



sanitary purposes. Fairly large quantities of zinc chloride might have 



been obtained, but "war profiteers according to custom made the 



price prohibitive." Copper sulphate could not be obtained, and sodium 



fluoride could not be made on account of the shortage of sulphuric 



acid. No other tried materials were available. Moll predicts that in 



the future most of the creosote will be used for fuel and its use as a 



wood preservative will be limited to marine work for which other 



preservatives are unsuitable. For ordinary purposes there will be an 



extraordinary increase in the use of water soluble salts, particularly 



sodium fluoride and corrosive sublimate. Due to the increased cost 



of wood, preservative treatment will have an important part in the 



economic program of the reconstruction period.
