creosote on a commercial scale. A good share of our creosote 

 at the present time is made from coal tar and a large part 

 of it is imported. There is no question that some time in 

 the future this material will be used for the preservation of 

 wooden material, such as ties, poles, mine timber, etc. 



Wood Gas. 



It is estimated that about 11,500 cubic feet of gas are 

 derived per cord of wood. On this basis there are produced 

 annually in New York State 2,2 11,V9 5,000 cubic feet of 

 wood gas every year, from 192,330 cords. 



This gas is used entirely as a fuel underneath the ovens at 

 the present time. In some localities in Germany and Austria 

 wood gas has been used for illuminating purposes, and it is 

 very possible that at some time in the future this may be 

 used for a much more economical purpose than as a fuel 

 underneath the ovens. This, however, is looking a long way 

 in advance and it is probable that for some time at least it 

 will continue to serve the purpose of fuel along with the 

 wood tar and coal or other fuel brought in to supply the neces- 

 sary amount of heat.
