FOREST PROBLEMS. 201 



and cutting off some of the weeds where the Pines have 

 seeded thickest. This practice should be followed at 

 least two years, after which but little attention of this 

 sort will be needed, as the Pines will probably be able 

 to take care of themselves from then on. If the land can 

 be used for sheep pasture for one or two years, most of 

 the weeds and bushes will be destroyed, and the land 

 will be left in improved shape for the treatment outlined 

 in dragging the land to get it into good shape for a seed- 

 bed. In fact, without any further treatment the Pine 

 will probably come in unless the land is very heavily 

 pastured. 



9. A has 2,000 acres of land in Northern Minnesota 

 without any seeding trees. How can he secure a stand 

 of Pine upon the land? 



Answer: In such a case the best way is probably to 

 set out Pine seedlings, pulled from the woods, setting them 

 about twenty feet apart each way. This will require about 

 400 plants per acre. If the work is done early in the 

 spring there should be no great trouble about securing 

 a good stand. These trees will be crowded by weeds on 

 the land, which may help them to take an upright growth, 

 but they should be watched, and the weeds kept in check, 

 if they are liable to overcome them. After a few years, 

 the Pine will be improved by the crowding of Poplar and 

 Hazel brush, which is generally found upon such soil. 



10. A has a half section of moderately good land, 

 covered with an even-growth of White and Norway Pine. 

 He would like to maintain a stand of Pine on this tract 

 not that he thinks it especially profitable, but that it 

 would prove an interesting experiment. 



Answer: Even-aged Pine is very difficult of renewal 

 without clean cutting, and it is quite out of the question 

 to handle such tracts to advantage on the selection system. 

 There is practically no such thing as even-aged Pine over
