As the number of plants was equally distributed over all 
the fields, we can here compare the average of the weight 
of the roots. This gives an increase of 10°4 per cent. for 
the experimental field; but as the growth in the roots 
depends upon, besides other circumstances, the greater or 
less number of leaves which the plant is spreading in the 
air, it is preferable to compare the squares where the 
weight of the leaves was nearly alike—that is, the experi- 
mental fields 1 and 3 and the control field 2, and likewise 
experimental’ field 2 and control fields 1 and 3. The 
former gives an increase of 13:0 per cent. and the latter 
38°8 per cent. ;

Only two squares could be compared with each other, in 
consequence of the unequal development in the other fields,
