UseE OF CREOSOTE OIL IN THE UNITED STATES. 
Within the last four or five years there has sprung up in the 
United States a large demand for creosote oil on the part of 
the railway companies, who have commenced to creosote the 
sleepers and other timber used on their lines. In many parts 
of the States, timber is now very scarce, and consequently 
commands a high price, owing, no doubt, to its lavish and 
wasteful use in the past, and also the almost total neglect to 
plant trees. 
Oil is sent from Canada, involving a journey by rail of 1500 to 
2000 miles, and large quantities are also shipped from this 
country. 
This should encourage tree-planters at home; for all the 
signs of the times point to a coming scarcity of timber, unless 
tree-planting is vigorously taken in hand by all countries which 
possess suitable soil and climate.
