altogether too wet for bottoms ; yet we have the largest crop 

 probably ever made in this section, bottom and top ciop 

 heavy, middle crop scattering." 



Mr. Turner is undoubtedly right in stating that other 

 things besides humus and chemical elements are connected 

 with epidemics of rust. Favorably seasons may go far to- 

 ward otf-setting the ill effects of poor soils and again on the 

 best of soils unfavorable seasons may produce sporadic out- 

 breaks of the disease. When the sum of all the conditions is 

 such that the cotton plant grows continuously and without 

 interruption from one end of the season to the other there will 

 be no rust. To produce a serious outbreak of the disease 

 we must have, first, conditions that check the growth of the 

 cotton and impair its vitality ; and, second, weather condi- 

 tions that favor the rapid growth of the fungus enemies that 

 are connected with the disease. As the factors that go to con- 

 stitute climatic conditions or « the seasons" are so largely be- 

 yond our control, it is only by ameliorating the condition of 

 the soil that we can hope to cope with the disease, and even 

 then our best efforts may sometimes be foiled by exceptionally 

 unfavorable seasons. 



Experiment on the Farm of the District Agricultural 



School at Abbeville, Ala. Undertaken by 



Prof. S. T. Slaton, the Agriculturist, and 



Keported on by His Successor, Prof. 



P. M. McIntyre. 



Plot No. 1.— Stable manure in the drill. 

 Plot No. 2. — Stable manure broadcast. 

 Plot No. 3.— Kainit. 

 Plot No. 4.— Check. 



Under date of October 13, Prof. Mclntrye reports that 

 plot 4 was very badly rusted and in fact had no leaves left on it. 

 The other three plots all had plenty of foliage left but all had 

 suffered to some extent. Plot 2, with manure applied broad- 

 cast, seemed to be in the best condition ; plot 1 next and plot 

 3 next.
