WINDBREAKS FOR ORCHARDS. 421 



Prof. Green: I would like to ask Prof. Hansen a question. If he 

 were to set out a grove for a windbreak, how far apart would he 

 plant them. Would he put the rows eight feet apart and the trees 

 two feet apart in the row? 



Prof. Hansen: That would depend whether you wanted them for 

 a windbreak or for fire wood. 

 Prof. Green: And what varieties would you plant? 

 Prof. Hansen: The white elm and the ash are among- the best. 

 Prof. Green: How far apart would 5'ou plant those deciduous 

 trees on the prairie for protection? 



Prof. Hansen: I would plant them four feet apart each way and 

 thin afterwards. 



Prof. Green: I would not put them closer. You can cultivate 

 them one way for a good while, and it is necessary to cultivate them 

 in order to keep out the blue grass. 



Mr. Wedge: Four feet apart each waj'- would be your way. Prof. 

 Green? 

 Prof. Green: Yes, sir. 



Mr. Somerville: The most successful plantation we had was set 

 4x6 feet and then cultivated and then thinned out until they were 

 ten or fifteen feet apart. 



Pres. Underwood: Mr. Barrett, how far apart would you plant 

 them? 



Mr. J. O. Barrett: I would plant them four feet apart. 

 Mr. Wyman Elliot: For fuel and also for a windbreak? 

 Mr. Barrett: I would plant them like Prof. Green. If the inten- 

 tion is to have a wood lot I would plant them close. It seems to me 

 we should make a distinction in regard to the species of trees for a 

 windbreak with reference to planting them a certain distance apart. 

 If I wanted to plant white willows I would plant them two feet 

 apart. If I were to plant ash I would have them not less than three 

 feet apart, but the box elder is a light shading tree and does not re- 

 quire as many trees as the green ash to produce a light shade. In 

 the region where Mr. Richardson lives, as I understand his locality, 

 it is not necessary to plant them so thickly, as they would not live. 

 We have got to get our trees very close together to break the wind. 

 Mr. Busse: I do not think we should set them so close in such 

 dry seasons as we have had lately. There is no moisture retained 

 in close planting like that. The people have found it so themselves, 

 and they said they would not set any more trees that distance. 

 Pres Underwood: How far apart would j^ou plant them? 

 Mr. Busse: 6x8 feet each way. 



Mr. Elliot: I have always had a theorj'^ about windbreaks. If I 

 were going to put out a windbreak on the prairie, I would not be too 

 particular to plant them, as I would on a town lot. If I had plenty 

 of land, I would have my rows six feet apart, so they would be in 

 quincunx form. You plant your trees four feet apart in the rows 

 and then put the next row six feet away and have the tree come in 

 the space between, and so continue throughout. 



Pres. Underwood: How would you plant a windbreak of ever- 

 greens?
