large areas in this State. It is probable that this land 

 could be best renewed by the group or strip method. The 

 land should be burned over clean after cutting, care being 

 taken to protect any good groups of seedlings that may 

 occur. A stand of young seedlings should be secured 

 on each piece of land cut over before further cutting is 

 done. If grass or brush is coming in too fast, it will prob- 

 ably be a good plan to go over the land with a log-drag 

 in August of the best good seeding year after cutting, so 

 as to loosen the soil, that the seed may have a good chance 

 to start. Grass and weeds often prevent the growth of 

 Pine seed, or even kill out the young seedlings after they 

 are started. 



11. A would like to have a good shelter-belt about the 

 buildings on his prairie fann, in Central Minnesota, and 

 would like if it could be made to furnish fence posts and 

 fuel. He could use ten acres for this purpose. 



Answer: He will probably come nearest to accomplish- 

 ing this if he makes a solid planting of White Willow, as 

 recommended on page 165. 



12. C has a farm on rolling prairie. It is all under 

 cultivation or used for pasture. He feels the necessity 

 of having a home supply of fence posts and light fuel. 

 Thinks of putting his wood lot on the rich bottom land. 

 The soil is a sandy drift, some ridges being more sandy 

 than others, and in a few places are bare from washing. 



Answer: Since the bottom land resists drought better 

 than the high land, it would be better to keep it for agri- 

 cultural purposes, and to place the trees on the ridges, 

 where the soil is too bare to jdeld a return from agricul- 

 ture. He could probably plant White Willow in these 

 locations to good advantage, and get what he needs in 

 fence posts and a considerable amoimt of summer fuel. 

 It is probable that on such land there would be a yield 

 of about three cords per acre of fuel wood per year, much
