262 THE AGEICULTUEAL EXPEPJMEXTS AT WOBUEX. 



The manurial treatment of each rotation area during the whole 

 rotation may be summarised as follows : — All the plots are 

 dunged with manure derived partly from sheep and partly from 

 oxen. Those whose manure was applied to plot 1 received in 

 the four years of the rotation extra fodder, consisting of 1728 

 lbs. decorticated cotton cake. Those whose manure was applied 

 to plot 2 received extra fodder, consisting of 1728 lbs. maize 

 meal. Those who supplied the manure for plots 3 and -4 received 

 no extra fodder, but in lieu of that the plots received artificial 

 manures considered equivalent to the manures derived from 

 the extra fodder consumed on plots 1 and 2 respectively. 



The amounts of wheat and barley produced during the rota- 

 tion will thus be a measure of the value of the manures oljtained 

 by the consumption of cotton cake as against an equal amount 

 of maize-meal, and also a measure of the value of these as against 

 artificial manures calculated to contain the same amount of fer- 

 tilising material. 



Owing to the short period during which the investigation has 

 been going on it would be premature to consider the results of 

 the cropping as yet obtained. AVlien a full rotation has been 

 accomplished in each area it will be interesting to note the 

 results, but even then it will be found expedient, or perhaps 

 necessary, to await the results of a second or even of a third 

 rotation before it will be possible to estimate with approximate 

 accuracy the values of the unexhausted manures derived from 

 the consumption on the land of decorticated cotton cake and 

 maize-meal, and to deduce from these a series of comparative 

 values for manurial residues derived from other forms of fodder. 



The same remark applies to the other experiments on the 

 continuous growth of white crops. They occupy an area of 5| 

 acres, and have been going on for three years. Into the details 

 of that part of the work at Woburn it is unnecessary here to 

 enter ; they are very similar to those referred to as being con- 

 ducted on Broadbalk Field and Hoos Field at Ptothamsted. 



It only remams to add that the deputation from the Society 

 who visited the station and carefuUy inspected the various ex- 

 periments were much pleased with the care and accuracy dis- 

 played in all the arrangements made for carrying on the investi- 

 gations. They were much impressed with the liberality of the 

 clonor of the station, to whom the Eoyal Agricultural Society 

 are also indebted for the use of a neighbouring farm of 90 acres, 

 and all that it can supply in the way of horse and hand-labour 

 and material for the successful carrying on of the experiments. 

 An enterprise so liberally founded and maintained, and so skil- 

 fully conducted, cannot fail to achieve important results for the 

 "ood of agriculture.
