to a sustained-yield basis, without adding to the 
timber holdings would require reductions in 
output of about 25 percent for 4 mills, 50 percent 
for 12 mills, 75 percent for 4 mills, and the elimi- 
nation of 21 mills. Thus, even though some of the 
poorer mills will doubtless pass out of the picture 
at an early date, the industrial capacity will still 
exceed the productive capacity of the tributary 
forest. On the other hand, new mills will be 
needed in some of the undeveloped districts. 
The south-central part of the Peninsula, sur- 
rounding Iron Mountain and Menominee, for 
example, has been largely cut over. ‘The present 
sawlog requirements of mills at Iron Mountain and 
Hermansville and of small plants in the area 
amount to about 85 million board feet annually. 
At this rate the mills could use all the local timber 
in 6 or 8 years, with the result that some 4,500 
men now employed in them would be left stranded. 
On a selective-logging and perpetual-yield basis, 
the local forests would sustain an annual cut of 
10 to 14 million feet and afford permanent employ- 
ment for about 1,100 men. ‘The pulpwood situa- 
tion is similar; the normal annual drain, 30,000 to 
40,000 cords, is more than double the forests’ 
sustained-yield capacity. Local forests would even 
fall short of supplying perpetually the requirements 
for chemical wood. 
The district surrounding Escanaba, Wells, Glad- 
stone, and Manistique exhibits similar conditions. 
Local industries normally require about 66 million 
feet of saw timber per year, whereas sustained- 
yield management would permit a cut of only 
16 million feet a year during the next 25 years.

The cut of pulpwood is three times the yield 
capacity of the forest. If this district were placed 
on a sustained-yield basis today, employment in 
woods and mills would be reduced from about 
4,200 persons to 1,220. 
Sault Ste. Marie has already made its acjustment, 
and the annual wood requirements of its remaining 
mills can doubtless be accommodated by the 
residual timber in the surrounding area. 
A number of areas are capable of supporting 
greater local industrial activity. The district 
surrounding Marquette, according to survey cal- 
culations, could support twice the present normal 
lumber production if a good system of forest 
management were adopted. It could go much 
further than at present in supplying the needs of 
the local chemical industry and continue to export 
18,000 to 20,000 cords of pulpwood. Instead of 
850 men as at present, permanent jobs could be 
given to at least 1,200. Expansion in production 
of local industries will not be possible, however, 
if outside industries increase their operations in 
this territory. 
The territory tributary to Munising, with good 
management, is capable of providing 50 percent 
more saw timber than local industries now demand. 
But there is some danger that this margin will be lost 
through overcutting for pulp and chemical wood. 
The greatest undeveloped resources lie in the 
extreme western end of the Peninsula—in Baraga, 
Ontonagon, and Gogebic Counties. Here, even 
with selective logging, production and employment 
could be maintained at the present level and in 
some places increased.
