Experiments in 1856. 
The following experiments were conducted on a poor gravelly soil, in order 
to ascertain the etlect of artificials applied loosely on each crop sown the 21&t 
of May, and raised the 12tli November, 1S56 : —

This experiment shows most distinctly that a combination of farm- 
yard manure with some species of artificial manure is generally the 
best method of obtaining the greatest amount of mangold. 
Experiments in 1860. 
The following experiments were conducted on the crop of 1860 in order to 
ascertain which manures would raise the greatest weight per acre of mangolds 
in conjunction with farmyard dung. Field, a light .soil ; seed drilled on 
27-inch ridges first week in May; dung applied in the ridge at time of 
sowing; the artificials sown by hand over the dung to insure equal distribu- 
tion ; crop stored in the second week of October : —

In this latter series of experiments the dung vcas applied at the time 
of sowing on the ridges. That is a matter which must depend very 
much on the soil. On heavy soils, which it is difficult to get upon at 
certain seasons, the early application of manure is no doubt excellent ; 
but on lighter soils it is better to put it on the ridge just before sowing 
the seed. This series of experiments, taking the value of the produce 
at 12s. Gd. per ton, which is a fair amount, and allowing for the cost 
of the application, gives the highest gain to the 2 cwts. of guano and
