STATISTICS AND HLSTORY. 



The shortage of timber supply for staves 



Cost has caused considerable alarm to interested 



of manufacturers, and the problem is daily 



Staves growing more serious. Recent reports 



from six members of the Valuation Com- 

 mittee of the National Tight Barrel Stave Manufacturers' 

 Association .shows that in the past 10 years there has been an 

 increase in the average cost of timber per cubic cord in the tree 

 of 337 per cent. It shows that timber to-day is costing nearly 

 four and one-half times as much as it did ten years ago. The 

 average cost of cutting bolts per cubic yard has increased 60 per 

 cent, and the average cost of hauling bolts from the tree to the 

 mill has increased nearly 300 per cent, which is probably due to 

 mills hauling timber greater distances, as well as the advance in 

 the cost of labor. The cost of custom bolts has advanced 78 per 

 cent, and the cost of mill labor per thou.sand staves has increased 

 40 per cent, the cost of hauling staves from country mills to rail- 

 road stations has increa.sed 125 per cent, which is probably due 

 to mills being located farther back from the railroad, as well as 

 the increased labor cost. 



' ' The average of fixed charge in connection with the operation 

 of stave mills has increased 75 per cent. On the other hand, 

 there has been a decrease in the same period of time of the
