20 MINNESOTA STATE HORTICULTURAL SOCIETY. 



Mr. Husser : I would like to know whether it is a good plan 

 to dynamite say just a week or so before planting, or if the 

 dynamiting should be done some months ahead so the fumes get 

 out of the ground? 



Mr. Lee: I don't think the fumes make any difference, I 

 think they get out of the ground very quickly. I don't think 

 there would be any advantage in dynamiting beforehand. Es- 

 pecially if a rain should come and pack your hole, it might be a 

 disadvantage. 



Mr. Husser: Does root-gall spread from one tree to the 

 other in an orchard? 



Mr. Lee : That would be hard to tell ; I don't think anybody 

 knows. I don't think it does ; I think it would be from contact. 

 It might be spread by tools used on a diseased root and then on 

 some other root. 



Miss Funk: I would like to know whether scions should 

 be taken from old trees or young trees. 



Mr. Lee: The best advice I can find on the subject is to 

 take them from bearing trees. 



Mr. Brackett: What advantage, if any, is there in using 

 scions from top-worked trees? 



Mr. Lee: I don't know that there is any advantage. I got 

 them because that was the only kind that existed in Minnesota 

 of those varieties. 



Mr. Powers: Where you have a tree that you are afraid 

 isn't going to live very long but it may live some years, and you 

 think it would be well to put a new tree near it, would it hurt 

 the roots of the old tree to dynamite not far away? 



Mr. Lee: You mean a large tree? 



Mr. Powers: Yes, sir; one you don't think will live more 

 than two or three years. 



Mr. Lee : I don't think it would hurt the roots to dynamite 

 in the rows. 



Mr. Powers: I mean, if you put it three or four feet away 

 to one side, would it spoil the roots of the tree? 



Mr. Lee : That would be pretty close ; it might injure them. 

 It depends upon the size of the trees. You might injure the 

 ends of the roots of a large tree near it. 



Mr. Powers: In a western paper it says with a tree that 

 is not growing well to put sticks of dynamite three or four feet 

 away and loosen the earth. 



Mr. Lee: It would depend on the soil. If you had a soil 

 with a good deal of rock in it and with a hard-pan down a couple 

 of feet it might be a good thing. 



Mr. Crosby: I wish to transplant some trees which I have 

 to a new place. When shall I do it, in the fall of the year or 

 when the ground is frozen? 



Mr. Lee : Why not transplant them in the spring? 



Mr. Crosby: Some of the trees are four or five inches 

 in diameter. I am quite anxious to save them.
