than kill the parasite on the surface." All authorities agree, 

 however, in advising that all infected trees should be rejected, 

 and many urge that no trees from nurseries where crown gall 

 is known to exist should be planted. 



CONCLUSIONS. 



1. Crown gall is not a disease over which to be greatly 

 alarmed. It may in the future become serious but at present 

 it is not doing any vast amount of damage. 



2. The cause of crown gall is not known. 



3. All experimental work done up to the present time indi- 

 cates that the disease is communicable. 



4. No remedy has been found for the trouble. As a pre- 

 cautionary measure no trees obviously infected should be 

 planted. If a great many trees in the consignment are dis- 

 eased none should be planted but the whole shipment should be 

 returned to the person from whom the treees were bought. 



5. Since so little is known of crown gaU, the need of accurate 

 and scientific experimentation upon the supject is obvious. Not 

 until this is done will the crown gall controversy be settled to 

 the satisfaction of all.

 splendid apples. They were clean and bright and exceedingly 

 attractive. One large table was devoted entirely to new seed- 

 lings and among them were many of great merit. Never was 

 there a more persistant, determined and heroic band of men 

 who in the face of every obstacle have pushed on to success, 

 and the results are most cheering. One by one the old veterans
