The manner of securing the results are clearly 

 open to objection, but they may show some indications. 

 Plats 5 and 9, when compared with the whole, show a de- 

 crease in nitrogen in the crop, but when compared with plats 

 4 and 10 respectively, the decrease is but slight except 

 where corn grew in Plat 9. The corn in this plat is cal- 

 culated the same as in Plat 5, which is probably too low 

 since the corn yield was 33^ greater in Plat 5. Allowing 

 for this probable error, there appears to be about the 

 same yield of nitrogen in the ends as in the cor:% on these 

 two plats . 



The nitrogen in 2 to 7 inches of soil is lower 

 in these plats than any of the others. Plat 2, which 

 was scraped, shows the highest amount of nitrogen in the 

 soil of any of the plats, but the total nitrogen in the crop 



was low . 



— CAPILLARITY — 

 For the study of the differences in the capillary 

 power of the soil the results from plats 1 to 13 were used, 

 since the greatest variations in texture oocxirred in these 

 plats. The variations from the approximate normal for the 

 different plats, and between the ends and in corn is shown 

 in Table XXXXVII .
