Iii the case of the plats receiving annually large quantities of 
Organic mEtter in 1 1 1 * * form of dung or rape cake th<> soil necessarily 
becomes more bulky or porous and absorbent, and therefore lighter 
as regards the surface soil. Table 6 shows the determined weights of 
the dunged plats, -a and l'1>, and of the rape-cake plat at different 
periods, and also their calculated weights based on the assumption of 
an average yearly decrease in weight corresponding t<> increment of 
organic matter. I'lat 2a, it will be remembered, has received 11 tons 
of farmyard manure every year since 1 ss J -that is to say, for only 
nine years previously to the L893 sampling — while plat 2b had received 
14 tons of farmyard manure every year for fifty years. Plat 19 has 
for many years received about In* hundredweight of ground rape cake 
per annum.
