most part brought up to date, relating to Rain and 

 Drainage, and to the results of the Field experiments, 

 on Wheat, Barley, Oats, various Root-crops, Potatoes, 

 Rotation, and Permanent Grass ; also to Leguminous 

 crops, but so far as they are concerned numerical results 

 are not given. Careful attention should, however, be 

 given to the descriptions, lists, and summaries, in the 

 " Memoranda." 



It is to be presumed that the areas of land trans- 

 ferred to the Trustees, indicate pretty clearly the 

 importance to be attached to the various Field experi- 

 ments which have been carried on, or are still in 

 progress. They are, accordingly, the experiments on 



1. The continuous growth of Wheat, in Broadbalk 



Field. 



2. The continuous growth of Barley ; also those on 



Leguminous crops, Wheat alternated with Fallow, 

 and Potatoes, in Hoos-ficld. 



3. The continuous growth of Root-crops, in Bamfield. 



4. Rotation of crops, in Agdell Field. 



5. Permanent Grass, in The Park. 



It will be observed that the scheme comprises experi- 

 ments with individual typical elements of a rotation of 

 crops, namely wheat and barley representing cereals, 

 various root-crops, and various leguminous crops ; also 

 experiments on the crops grown in an actual course of 

 Rotation. Experiments on the mixed herbage of per- 

 manent grass-land are also included. Thus, so far as 

 crops are concerned, the characteristic elements of our 

 agriculture are investigated, both as to their intrinsic or 

 individual characters, as shown by their growth year 

 after year on the same land under different conditions 

 as to manuring, and as to their relative or com- 

 plementary characteristics, as grown in rotation. 



After careful consideration of the subject with Sir 

 J. B. Lawes, it was agreed, that the various experiments 

 enumerated, with perhaps the exception of those with
