heavy application of Ifainit on plots 3 and 4 still showed no 

 effect whatever. At this date there was a little spotting of 

 the foliage in this field, but not enough anywhere to do ma- 

 terial damage. The pronounced effect of the nitrogenous 

 fertilizers and the lack of effect from the potash and phos- 

 phate in this field was a great surprise, as it was thought that 

 the previous pea crop had furnished nearly nitrogen enough 

 to supply the needs of the cotton crop. The general better 

 tilth of the land on account of the pea crop at least served to 

 ward ott" the rust, as many neighboring fields suffered badly, 

 although the trouble was less serious than in 1897. 



MooRE Experiment No. 2.— The land for this experiment 

 was selected because it was very old and thin, and had the 

 reputation of being more subject to rust than any other field 

 on the farm. It was in cotton in 1897 and the crop was prac- 

 tically all ruined by ruse. The fertilizers were not put down 

 for this experiment till April 12. As in the other case all re- 

 ceived Mr. Moore's "potash phosphate" at the rate of 100 

 pounds per acre. Here the rows were about 18 rods long, and 

 the following plots were laid out : 



Plot 1— Check. 



Plot 2 — Kainit at rate of 500 pounds per acre. 



ptot 3 — Kainit at rate of 500 pounds per acre, acid phos- 

 phate at rate of 200 pounds per acre, and nitrate of soda at 

 rate of 100 pounds per acre. 



Plot 4— Check. 



Plot 5 — Kainit, 500 pounds per acre. 



Plot 6— Check. 



Plot 7 — Muriate of potash, 125 pounds per acre. 



Owing to a misunderstanding Mr. Moore had used all of, 

 his stable manure so that none was available for this test. 



On August 8 the check rows were found to be very poor, 

 plants only 12 to 18 inches high, and carrying very few bolls. 

 The foliage was badly spotted and fully 10 per cent, of the 

 plants had entirely lost their leaves. 



In the kainit plots the plants were about twice as tall as 

 in the check rows. They were slender and not much branched
