old worn lands where the cows were penned until the land 

 became rich. When the pens were removed and the lands 

 planted in cotton there was no rust on the rich spot, but all 

 around it rusted badly. * * * I have tried kainit with 

 compost and with other manures. While probably there is 

 some good in it, in my judgment it should not be recommended, 

 to eradicate rust. 



From C. C. L. Dill, Dillberg, Ala.: 



" 1. I have used kainit and have not suffered from rust 

 during 1896 and 1897. Before I began the use of kainit Host 

 by rust. 



" 2. Soil sandy loam with clay subsoil. 

 ' o. I use 100 lbs. kainit, 100 lbs. acid phosphate, and 100 

 lbs. guano per acre in the drill. 



" 4. In rich land,'hew or old, where the plants are strong 

 and thrifty, I have never been seriously injured by rust. 



5. "The very best cotton that we have is in old fence 

 rows, near barns or old cow pens, especially the cow pens." 



From R. P. Johnson, Smithville, Ga. : 



" We have had rust in this section the past year a little 

 worse than the previous year, next crop we expect to have 

 still more. I have had the rust problem solved ever since it 

 first made its appearance to any extent in this section. Have 

 not planted any cotton for ten years. I am satisfied that I 

 could plant a crop and not have a rust spot on it. Why ? Be- 

 cause it has had a rest from constant clean culture. It has 

 been run in corn, watermelons, peas, oats, vegetables, and 

 right here lies the whole solution of the lust trouble: diver- 

 sity of crops is the key note to the whole business." 



From G. H. Turner, Burgess, Miss.: 

 • "1. Yes, some of our cotton suffered badly in 1897. We 

 suppose loss would amount to at least 50 per cent, in some 

 patches, while in others in similar soils and under apparently 

 exactly similar conditions there "was none. 



"2. A sandy loam. Kust has been worst in lowland, 

 branch bottoms, and on old well worn land that was deficient 

 in humus. The mere fact of its lowness cuts no figure, from 

 the fact that the land on which we made three bales per acre 

 was still lower. 



" 3. Have never used kainit as a preventive of rust, but 

 have used fertilizers containing kainit. Have never had the 

 slightest trouble whenever and wherever complete fertilizers 

 were used. Last year a piece of ground right through the 

 center of a cotton patch to which 'phosphate alone was applied,
