group those on which the writer has never found the disease. These 
groups are as follows: 
1. Yellow Newtown (or Albemarle Pippin), Shackleford, Bentley, 
Gibbs, and Missouri. 
2. Arkansas Beauty, Limbertwig, Rhode Island, York Stripe, 
Huntsman, Pilot, Peck, Northern Spy, Jonathan, Northwestern 
Greening, Fall Cheese, Stark, Green Sweet, and Nero. 
3. Grimes, Ben Davis, York Imperial, Gano, Arkansas, Ivanhoe, 
and Winesap. 
4. Coffelt, Bismarck, Pewaukee, Stuart Golden, Pryor, Salome, 
Scarlet Cranberry, Oliver, Roxbury, Lankford, Loy, Ralls, Craw- 
ford, Carlough, and Akin. 
Mr. F. W. Faurot, of the Missouri State Fruit Experiment Station, 
a collaborator of the Department of Agriculture, has kindly furnished 
the following information relative to the susceptibility of the different 
varieties of apples in the State of Missouri. He has arranged the 
varieties in their approximate order, with the most susceptible varie- 
ties first, in four classes, which do not necessarily coincide with the 
four classes given above. They are as follows: 
1. Willow and Huntsman. 
2. Ben Davis, Gano, Ingram, Smith, Rome, York Imperial, Clay- 
ton, Nickajack, and Nixonite. 
3. Lowell, Porter, and Maiden Blush. 
4. Arkansas, Arkansas Black, Jonathan, Grimes, Winesap, and 
Gilpin. 
Mr. Faurot writes concerning this list as follows: 
In some seasons, however, this third group comes next to Willow and Huntsman, 
for when they bitter-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 about 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 ina plaee. I have never seen it, 
however, on White Pearmain, Yellow Transparent, or Red Astrachan. ‘This 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 disease,
