AND HORTICULTURE, 19 
§6. The following year, in the summer of 1899, the 
experiments were again removed to Brédtorp, where Baron 
E. Hisinger, with his usual benevolence and never-failing 
interest, gave us some land and caused the necessary work 
for the culture of the plants to be continued. As stated 
above,the greatest difficulty in such experiments, when a 
comparison between the harvest from two fields had to be 
made, lies in obtaining homogeneous soil—that is, a soil 
which fully possesses the same qualities of fertility. As this 
is dependent not only on the elements of which it is com- 
posed, but also on the depth of cultivation and humidity of 
the soil, the choosing of the land is very difficult. In order 
to overcome these difficulties, at least to a certain degree, the 
following method was introduced. It will be best illustrated 
through Fig. 3 below :—
