struments, one hundred and twenty-five manufac- 

 turers of sash, doors, and blinds, in addition to a 

 very large number of concerns producing planing- 

 mill and other products of wooden construction. 

 These factories consumed, in 1910, 1,282,000,000 feet 

 of wood, costing $29,050,000. The ten years inter-

 which afforded the foregoing data, has seen the de- 

 velopment to stupendous proportions of the automo- 

 bile industry of Michigan, itself an enormous con- 

 sumer of forest products. While definite informa- 

 tion is not available, there seems a tendency for 

 wood-using industries to transfer the scene of their 

 operations to the northern peninsula, whose forest 

 resources are less depleted Statistics prepared by 

 the Upper Peninsula Development Bureau early in 

 1920 indicate the presence in the Upper Peninsula 

 of eighty-six saw-mills, four tanneries, four paper 

 mills, six wood carbonization plants, six handle fac- 

 tories, two box factories and one excelsior plant. The 

 establishment at Iron Mountain of a plant for the 

 manufacture of wooden parts required by the Ford 

 Motor Company was itself a significant indication 

 of the drift northward of the wood-using industries. 

 In addition to this very large output of factory 

 products, the State has been called on to furnish 

 out of its forest resources great quantities of mine 

 props for the underground workings of its own iron 

 and copper mines, of poles and posts, the estimated 

 product of the Upper Peninsula in 1920 being 3,000,-
