As all the rotations are the same, a detailed description of any 

 one will be applicable to the others. It will be sullicient there- 

 fore to d('scril)e the course of operations on Kotation 1. In 1877 

 it was under seeds (urass and clover). Ten sheep were put into 

 each acre-plot to eat down the crop; those on plot 1 Imd 728 lbs-, 

 decorticated cotton cake given them as additional fodder; 

 t]i(»se on ]dot 2 received 728 lbs. maize-meal ; while those on 

 plots .'] and 4 had no additional fodder. 



In 1878 the four plots were under wheat; ]ilnts 1 and li 

 received no manure except that left liy the sheep during the 

 former season ; plot ?i received in addition an artificial manure, 

 containing nitrogen, phosphoric acid, and ])otash e^^ual to that 

 calculated to be contained in the manure derived from 728 lbs. 

 decorticated cotton cake: A\liile ]>lot 4 received an arti- 

 ficial manure containing nitrogen, i)hosplioric acid, and potash 

 equal to that calculated to be contained in the manure derived 

 from 728 lbs. maize-meal. The crop was cut and carried oif^ 

 and the produce of each plot weighed separately. 



In 1879 the four plots were under roots, for which the land 

 Avas dunged. The dung was made by four pairs of stall-fed 

 oxen, which received as fodder per pair 5UO0 lbs. mangolds and 

 1250 lbs. wheat straw chaff', and for litter 3230 lbs. straw. Pair 



1 received in addition 1000 11)S. decorticated cotton cake; pair 



2 received in addition 1000 lbs. m-aize-mcal ; while pairs 3 and 

 4 received no additional fodder. The manure from })air 1 wa* 

 applied to plot 1, that from pair 2 to plot 2, and plots 3 and 4 

 received the manure of pairs 3 and 4 respectively. To ])lots 1 

 and 2 no artificial manure was ap[)lied ; l)ut plot 3 received ait 

 artificial manure containing nitrogen, phosphoric acid, and potash 

 equal to that calculated to be contained in the manure derived 

 from 1000 lbs. decorticated cotton cake ; plot4 received an artificial 

 manure containing these ingredients in the proportion calculated 

 to be contained in the manure derived from 1000 lbs. maize- 

 meal. As however the amounts of nitrogen contained in these 

 artificial manures are more than it is expedient to apply directly 

 to a root crop, only two-thirds of the amount of that ingredient 

 were applied directly to the roots, the other third being reserved 

 for the succeeding cereal crop. The mangolds thus produced, 

 after being weighed, were left on the ground to be eaten by 

 sheep — ten to each plot as before. 



In 1880 the crop will be barley. Plots 1 and 2 will receive 

 no manure in addition to that left by the sheep ; but to plots 3 

 and 4 will be applied the residual amounts of nitrogen held over 

 from last year's root crop. The barley crop will l)e cut down 

 and removed, and the produce of each jilot separately weighed.
