Briefly, the results show that in the frame building with a mean 

 temperature of 30.2° F. and relative humidity of 68.3 percent, the 

 tobacco dried too quickly and the leaves when cured contained many 

 green spots. In the cloth shed prior to putting on the white outside 

 canvas the temperature was very much too high and the tobacco was 

 badly damaged. After modification the mean temperature was 78.26° 

 and the relative humidity 70 per cent, and the conditions as shown by 

 the tobacco were more favorable than in the frame building. In the 

 large shed the mean temperature was 77.67 0 and the relative humidity 

 73.57 per cent. The tobacco in this shed was better cured than in 

 either of the others, and would indicate that the slightly lower tem- 

 perature and higher relative humidity were favorable to the best 

 results. 



FERMENTATION. 



The experimental crop of shade-grown tobacco was too small in 

 amount to make it possible to carry on a satisfactory fermenting 

 experiment with it. It was therefore combined with other tobacco 

 from the plantation and fermented. The writer gave personal super- 

 vision to the fermentation of all the tobacco of the plantation and 

 kept records of the temperature in the several fermenting piles, hav- 

 ing the piles torn down and rebuilt whenever the temperature reached 

 an elevation which indicated the necessity of this operation. Below 

 is given the temperature records of one pile, the tobacco of which 

 was grown outside and contained a high percentage of wrapper leaves. 

 The fermentation investigations were carried on in a stone building 

 of which two sides each had a window and a door that were not pro- 

 vided with means of being closed. These openings, through which 

 the wind frequently blew, made it impossible to properly control the 

 interior humidity, and in this connection it might be said that it is 

 always desirable to have the fermenting house so that it can be
