AND HORTICULTURE. 47 
With the turnips and the sugar beets the surplus of leaves 
is equal to the surplus of roots, while with the mangold 
this is not the same, and with the peas and beans the straw 
and the stalks are far more developed than the fruit itself ; 
this with the peas has given a positive result, but with the 
beans a negative one. This shows that the soil has become 
poorer and yet poorer on the experimental fields than on 
the control fields, and this is confirmed by the circum- 
stance that on the second experimental field potatoes and 
beans have given negative results and peas a low positive 
one. This poverty of the soil appears most striking in the 
reduction of the percentage of sugar, which the chemical 
analysis shows, concerning sugar beets, to be :—

The machine actéd upon an area of 517 m’%. 
Owing to a misunderstanding the machine had got a 
velocity about four times greater than was necessary. 
This acted badly upon the carrots, which were not watered. 
This crop has always, under such circumstances, given 
a negative result. Whether this too great velocity 
had any noteworthy influence on the other plants cannot
