The manures were all passed through a fine sieve, and, with the 
exception of the soot, mixed with fine coal-ashes, and then sown 
evenly over the different plots by Reeves' broad-cast manure 
distributor. This machine is a capital implement for sowing 
dry top-dressings. It is most essential that the mixtures should 
be quite dry, for if in the least damp they do not fall regularly 
upon the land, and the machine is apt to become clogged up. 
This is especially the case with substances which, like common 
salt, always feel more or less damp. Unless these are purposely 
dried, or mixed with diy, fine sand, we find they cannot be 
readily and evenly sown by this machine.

This wheat looked very healthy throughout the summer, but 
did not yield so well as Nos. 2 and 5. The effects of the top- 
dressing upon the young wheat were visible a week after its 
application.
