108 ENEMIES OK THE ORCHARD 



summer, and the first indication of the disease 

 should be met with the knife. Cut and burn, or 

 carry to considerable distance from the orchard, say 

 100 feet or more. The latter has been my prac- 

 tice, and I have never had blight in large orchards 

 and nursery to do any material harm. This is due 

 to prompt action. 



From the above it will be seen that in cutting 

 out the wood it must not be taken nearer to other 

 trees than is necessary, or we shall communicate it 

 to them. 



There are many things which we meet in inves- 

 tigating this that would cause us to doubt the posi- 

 tion taken by our scientists and microscopists but 

 which would not justify controversy here. The 

 treatment is the same, whatever the cause may be. 



In cutting it will not be enough to cut out the 

 parts that show the dead and withered wood, the 

 cut should be made a foot or more below the apar- 

 ent injury, if the shoot or branch will admit of it, 

 and where a small tree is badly affected, it should 

 be cut away entirely. 



This disease is much worse in the southern part 

 of Iowa and Nebraska, and in that latitude than it 

 is further north. It is also more common on the 

 Mississippi than the Missouri slopes, but it has no 

 limits, in the United States. 



To recapitulate, select high ground for the 

 orchard, if practicable, and avoid the hottest places, 

 especially where there is not a good air drainage, 

 which is of the utmost importance for this, as well
