mano-okls. The straw used as litter was cut rather shorter than 
in the preccdino: year, and instead of 1728 lbs. of straw used in 
each pen, only 1350 lbs. of straw, cut into chaff, were used as 
litter in 1880, 
The wheat-stubblc of the preceding year was ploughed for 
the first time on the 19th of February, 1880, and for the second 
time on the 23rd of April, at which time the dung was applied 
to the land. The dung was in a short and fairly rotten condition. 
The mangold seed was drilled in on the 28th of April, and the 
mineral manures were sown on the 6th of May, 1880. The seed 
came up well, and by the middle of May there was a good even 
plant all over the 4 acres. 
The nitrate of soda on plots 3 and 4 was sown by hand 
between the rows and round the plants on the 25th of June, 
1880, after the plants had been singled out and been well 
established in the land. 
The effects of the nitrate of soda soon became visible, 
and throughout the season the mangolds on plot 3 took the 
lead. 
In the beginning of November the mangolds were taken up, 
cleaned, topped and tailed, and weighed, when the results 
shown in the following Table were obtained :
