ruthlessness. indifference and lack of for- 

 est foresight. 



The building trades and the automobile 

 and furniture industries of Michigan must 

 largely import their supply of high-grade 

 lumber from other states instead of growing 

 it at home. 



For the most costly classes of woods, 

 such as those used for automobiles, furni- 

 ture and building, Michigan goes as far 

 south as the Gulf and as far west as the 

 Pacific ; she imports all told a little more 

 than a billion board feet of lumber and 

 timber annually, of which 400 million come 

 from the Gulf Coast region and nearly 180 

 million feet from the Pacific Xorthwest. 

 For these amounts the, state pays not only 

 an enormous freight bill but also the high 

 prices incident to constantly dwindling for- 

 ests. 



The reforestation of Michigan's denuded 

 lands would after a few decades, say for- 

 est experts not merely stop these costly 

 importations but go far toward reestablish- 

 ing the state's lost leadership in her once 

 greatest industry lumbering and put it 

 upon a permanent basis. 



AIRPLANE TO LOCATE ALASKA'S 

 LOST LAKES 



Locating and photographing undiscovered 

 lakes in the National Forests of Alaska are 

 the latest uses to which the airplane has 



AMERICAN FORESTRY 



been put, says the Forest Service, United 

 States Department of -Agriculture. 



It has long been known that there are 

 many lakes on the he,adlands and islands 

 traversed by the inside passage between 

 Seattle and Skagway that do not appear 

 on any map. During the New York-Nome 

 flight made, by Army aviators, lakes were 

 frequently sighted which could not be found 

 on the latest and most authentic maps of 

 the territory. Tales of unknown water 

 bodies are constantly being brought in by 

 trapper and prospectors. Less than a year 

 ago a lake 4>^ miles long and Vz mile 

 wide was discovered at the head of Short 

 Bay. This lake has over 1000 acres of sur- 

 face area and is less than 154 miles from 

 tidewater, yet because of the surrounding 

 territory's rough topography has remained 

 unknown and unnamed. 



Recognizing that many other of these 

 "lost lakes" may be sources of valuable 

 water power, the Forest Service has laid 

 plans to map this no man's land of the 

 north by means of aerial photographs. A 

 few days' flight, it is said, will be sufficient 

 to cover the area with a degree of accuracy 

 that would require many years and great 

 expense to accomplish by ordinary methods. 



The work, which has been approved by 

 the. Federal Power Commission, will be 

 done by seaplane, flying from Ketchikan as 

 a base.
