control field. But, besides that, the weight of 1,000 grains 
had augmented by 1°81 gr. on 27°04, or by 6°7 per cent. 
According to the statement of the Manager, Mr. Tillberg, 
the yearly average of produce per hectare for the three 
last years was in Atvidaberg 2,347kg., and was this year 
31°7 per cent. lower than this average. This circum- 
stance also caused a diminishing of the increase per cent., 
according to the rule already mentioned that “the better 
the vegetation the higher the increase per cent.” 
Barley. 
This crop was sown on the experimental and control 
fields on which the soil had been, as above mentioned, 
mixed. Calculated per hectare, there was obtained :—

The barley had thus given a surplus crop of 4o'1 per 
cent. and a 5°3 per cent. increase of first quality on the 
experimental as against the control field. The surplus 
weight of 1,000 grains is here only 0'05 g. 
Oats. 
The experimental and control fields were treated in 
the same way as for barley. The harvest, calculated 
per hectare, was :—
