of these are exceedingly valuable where the market conditions 
are in their favor. As to maple, Wisconsin lumber of this kind 
is now supposed to be inferior to the Michigan product, but the 
maple groves of lower Michigan are rapidly nearing exhaustion. 
Very likely the price of such lumber w411 rise considerably within 
the next twenty-five years. Then it may become profitable to 
set up a number of saw mills, of limited capacity, in Milwaukee, 
to utilize the hardwoods of this region. With proper manage- 
ment, the existing timber lots of this county would be capable 
of furnishing a permanent, annual supply of logs to such mills. 
The only condition would be that the individual owners of forest 
tracts would have intelligence enough to content themselves with 
an occasional, but substantial revenue by the sale of a limited 
number of trees at the proper time, instead of attempting to real- 
ize a small fortune at once by cutting and selling everything in 
sight. In anticipation of that time it will be wise for timber 
owners in this neighborhood to promote, by proper forestal man- 
agement, the growth of the more valuable species, particularly 
maple and oak, on their lands, so that they may participate in 
the profits, when market conditions shall become favorable.
