Mr. F. ^^^ Faurot, of the Missouri State Fruit Experiment Station, 

 a collal)orator of the Department of A^frieulture, has kindly furnished 

 the followino- information relative to the susceptibility of the different 

 varieties of apples in the State of Missouri. He has arranged the 

 varieties in their approximat(> order, with the most susceptible varie- 

 ties first, in four classes, which do not necessarily coincide with the 

 four classes given al)ove. They are as follows: 



1. Willow and Huntsman. 



2. Ben Davis, Gano. Ingram. Smith. Home. Yoi'k. Im])erial, Clay- 

 ton, Nickajack. and Nixonite. 



3. Lowell, Porter, and Maiden Blush. 



-t. Arkansas, Arkansas Black, Jonathan, Grimes, Winesap, and 

 Gilpin. 



Mr. Faurot writes concerning this list as follows: 



In some seasonn, however, this third ^roup comes next to Willow and Huntsman, 

 for when they l)itter-rot at all the whole crop usually goes, especially Lowell and 

 Porter. The reason I put them third is because some seasons they are out of the 

 way before bitter-rot attacks them or begins to develop with any degree of severity. 



The varieties given constitute al^out all of those that are grown commercially in 

 south Missouri. Aside from these, however, I have observed bitter-rot on very 

 nearly every variety of apple that I have seen growing in the State, including such 

 varieties as the ordinary Russets, Lawver, Northern Spy, Stevenson Pippin, Baldwin, 

 and many others that are grown only a few trees in a place. I hav^e never seen it, 

 however, on White Pearmain, Yellow Transparent, or Red Astrachan. Thjs is 

 merely my personal observation, however, and I have no« doubt that it occurs on 

 these varieties the same as on others, although I have not seen it. 



REMEDIAL MEASURES. 



Although bitter-rot has been known in this country as a serious 

 apple disease for at least thirty-five years, it seems that no attempt 

 was made to find a remedy for it until about 1888. During that year 

 Galloway" planned some experiments for the control of this disgase,
