in advance through the autumn, became more firmly 

 rooted, and much less of it was killed out by the winter. 

 Late in March, the field was again rolled. In April, a 

 considerable portion of the piece was harrowed ; the 

 teeth of the haiTOw used being so set that they run six 

 inches apart. 



Also in April, we spread bone at the rate of 9 bushels 

 per acre upon a portion of the rye where none had been 

 applied the preceding autumn. This bone was left up- 

 on the surface, and was neither rolled nor harrowed in. 



During the spring and early part of the summer, the 

 straw looked nearly as well where we applied 9 bushels 

 per acre as where the rate was 16 ; and this that was 

 boned had apparently four times as much bulk of straw 

 upon it in June as the other. 



At one time this rye wore a strange appearance : 

 nearly every straw was as white as it is now, in places 

 an inch, an inch and a half, or two inches long, and ex- 

 tended entirely around the straw. On some straws 

 these white rings were near the head, on others as low 

 down as the middle. We never saw or heard of any 

 thing of the kind before ; we supposed that the crop was 

 ruined, and commenced cutting up and feeding out to 

 our stock. In two or three days, however, we found 

 that the sap continued to flow, and we left off cutting. 

 The affection was seen as well on the parts not boned 

 as on those that were. 



On the 16th cf July, the rye was fit for the cradle, 

 and we then cut portions of it to be bound and threshed 

 separately, for the purpose of ascertaining the effect of 

 the different applications and different treatment. 



To do this fairly as possible, we took in the centre of 

 the field, the half of one of the lands made by ploughing ; 

 and in measuring, w^ent from the centre of the hollow or 

 dead furrow, to the centre of the ridge or back furrow. 

 Our applications had been so made that each of them 

 crossed this strip at right angles. We cut July 16 ; 

 threshed and measured July 28 and 29. The lots were 

 as follows —
