scions. Irresponsible shysters claim to have accomplished what vou know 

 they have not done. I say to you, gentlemen, you don't know the extent 

 of this fraud. The scion orchards, as a rule, are grown from trees known 

 to be true to name, and are the only practicable source from which scions 

 can be obtained. When a nurseryman takes his trees from a good young 

 scion orchard he knows he is giving to the public the very best thing that 

 can be given. 



N. F. Murray. — In south Missouri I would not plant aphis trees. 

 In north Missouri it does but little harm. Nurserymen throw out all 

 badly diseased trees upon the brush pile.' In my father's orchard in 

 Ohio fifty years ago, we threw away badly infested trees. I close by 

 saying that if you refuse to buy trees of all nurserymen who have root 

 gall or aphis you will have to quit the business. 



Mr. Ruddick. — In Crawford county we seldom see aphis above 

 ground. If we all cared for our trees and kept the borers out it would 

 not do much harm. Tobacco dust is used with good success against the 

 aphis. I don't think a little aphis on an apple tree is any worse than a 

 few fleas on a dog. 



G. B. Lamm. — I go among a good many orchards and I find but 

 little complaint of the nurserymen . 



C. H. Dutcher. — The aphis is also found on shade trees. I found it 

 upon young elms. 1 rid them of it by spraying with kerosene emulsion, 

 not too strong. Strong lye will do the same thing. There is no need 

 of throwing away a tree with the aphis any more than for throwing away 

 a young one who came from school with the itch. Nurserymen are not 

 going to send us trees with visible aphis upon them. Some men leave 

 the wrappers upon the trees too long and find the aphis under the wrap- 

 per. Wash them (?fif with kerosene emulsion, and put tobacco dust 

 around the root of the tree. Where the kerosene emulsion was too 

 strong there is no tree there now. My elm trees were pretty bad, but 

 one good washing cured them. 



Mrs. Chandler. — I cleared chrysanthemums of aphis with sulpho- 

 tobacco soap. 



Mr. Dutcher. — I do not throw away trees with aphis upon them. 



Prof. Stedman. — Nurserymen are now so particular that you will 

 find they will discard any tree that shows nodules. Occasionally you 

 may find a little aphis without nodules. In some instances nurserymen 

 may discard ten per cent., but this is rare. You need not hesitate to 

 plant any ordinary aphis tree shipped by responsible nurser^inen. Even 

 if you plant trees without aphis at all, they will have aphis w'ithin a year. 

 Then why not plant the slightly infested tree? You know it costs but
