tude. That from the Black Hills would be all right. It is the 

 easiest thing- in the world to raise. You can do it without any 

 trouble. I have tried it year after year and with the best success. 



Mr. Husser: Are they easily transplanted? 



Mr. Harrison : You don't want to plant in very dry weather 

 in hard ground. If the weather is damp and the ground is moist, 

 you can plant. The way I do, the second year we dig a trench 

 straight up and down. Dig it about six inches deep, put the 

 roots in the earth, push the dirt back with the hand and firm it. 

 You cannot get the roots in too solid. Let them grow there two 

 years and then put them in your forest. 



Mr. Husser: If the Ponderosa pine was planted on steep 

 side hills it would be a great thing for our state. 



Mr. Harrison : I planted Ponderosa pine that way. We have 

 a park in York where I planted some of those young pines, and 

 they are all right. You can get the most splendid result by plant- 

 ing the jack pine on side hills. If you have a north slope hill 

 you can plant the jack pine, if a south slope you plant the Pon- 

 derosa. The Ponderosa will stand any amount of heat. 



Prof. Shaw: The gentleman has raised an important and 

 practical question. Would you recommend the jack pine and 

 the Ponderosa under Minnesota conditions? 



Mr. Harrison. I should try them if I could get the right kind 

 of seed from the Black Hills. The Colorado foothill seeds do 

 well with Mr. Norby in South Dakota, but they do not always 

 prove satisfactory in this latitude. Plant them both. You can 

 probably get them set down here for half a cent apiece. I know 

 that I need not hesitate to give the name of the man growing 

 them. His name is H. B. Ayres, of Aitkin, and he sells a great 

 many of them. It is a pity to see all those that go to waste. 

 They grow from a hundred to two hundred miles north. There 

 are several kinds of jack pine. Newhall reports them as an ever- 

 green shrub, but Prof. Green and others find they grow very 

 thickly together and form a thick top. They grow the most 

 rapidly of all the evergreens. I find they beat everything else 

 of my eighteen kinds. In my evergreen book there is a picture 

 showing them growing in the sand hills of Nebraska thirteen 

 years old and twenty-two feet high. If you have a sandy posi- 

 tion select a patch and plant it, and you will be doing good work, 

 for you will be raising houses and barns.
