order to have a complete record of all constituents removed in the drainage 
water from the time when the soil samples were taken for analysis. Since 
the present report does not attempt to show the difference in the com- 
position of the soil at a later period, but is rather a discussion of the 
effect of the application of burnt lime on the composition of the drainage 
water and the plant ash, the drainage for the period previous to May 1 
1913, is not considered. 
Farm manure was applied to each of the four tanks in the spring of 
1913, the application being at the rate of 10 tons to the acre. Burnt lime 
was applied to tanks 15 and 16 in the spune of 1913 at the rate of 3000 
pounds to the acre. 
Tanks 14 and 16 were never planted to any crop, and growth of vege- 
tation on them was prevented by hoeing. In the year 1915, when maize 
was growing on tanks 13 and 15, the unplanted tanks were hoed at the 
same time and in the same way as were the tanks planted to maize; when 
other crops were growing on the planted tanks, the unplanted ones were 
merely scraped with a hoe. In each tank planted to maize there were 
aighteen maize plants. Seven rows of oats and the same number of rows 
of barley were sown in each tank planted to those crops. The barley 
was used to replace wheat, which had been sown in the previous autumn 
and had winterkilled. Canada peas were planted broadeast. All crops 
zrew to maturity and produced seed, but it was evident that the soil was 
not a very productive one. The manure, lime, and crop treatments are 
‘shown in table 5:
