On the Use of the Water-Drill. 
rows — generally eight — with the dry drill, using precisely the 
same quantity and quality of manure as was sown by the water- 
drill. Indeed it is only during the last two year* that 1 have 
discontinued this practice. But the results were so uniformly 
the same that it ceased to be necessary longer to make these 
experiments. I should also add that to test the v^^lue of the 
artificial manure used, as well as the comparative merits of the 
two drills, I for the first year sowed in every field two or four 
rows without any manure, and in no instance saw cause to regret 
the judicious application of an artificial stimulant to green orops. 
In 1854, the first year after I had purchased a water-drill, I not 
only made the experiments between that and the dry drill just 
referred to, but also, as regards the mangold crop, carefully mea- 
sured a portion of the field so sown, had the roots properly 
cleaned, and afterwards weighed, to ascertain exactly the relative 
merits and demerits of the two drills. The following Table will 
show the results : —
