OTHER KEfiOVRCES OF MICHIGAN 75 



1917, 203,907,000; and in 1918, 118,565,000 were 

 similarly reported. 



The combined hardwood and softwood types of 

 trees in Michigan represent a great variety of mer- 

 chantable types, and help to explain the presence 

 of many important wood-using industries in the 

 State, such as the manufacturing of planing-mill 

 products, boxes and crates, agricultural machinery, 

 automobiles, pulp and excelsior, handles, furniture, 

 toys and novelties. Of these varieties, maple — par- 

 ticularly sugar maple — has held a foremost position 

 among the hardwoods and white pine among the 

 conifers. Maple was native to all parts of the two 

 peninsulas. In 1910 Michigan was credited by the 

 United States Forest Service with producing more 

 maple lumber than all the remainder of the country 

 put together, and in 1918 with 40 per cent of the 

 country's output. In the latter year the 178 mills 

 reporting gave their product of this wood at 287,- 

 000,000 feet. It bulked large as planing-mill ma- 

 terial, where it figi;red much in the manufacture of 

 flooring. The Bureau of Forestry's report on "the 

 Wood-using Industries of Michigan" (1912) put the 

 consumption of sugar maple by Michigan planmg- 

 mills at 185,000,000 feet in 1910, of which 156,- 

 000,000 feet were grown in the State. In many other 

 industries also this wood holds an important position. 

 In the northern portion of the State, it is employed 

 in large quantities in the wood-carbonization plants, 

 in association with iron ore, for the production of 

 chemical l)y-products of the iron smelting furnaces.
