FOR APPROVED REPORTS. 



1. On the results of experiments for fixing and retaining the 

 volatile and soluble ingredients in Farm-yard Manure — Twenty 

 Sovereigns. To be lodged by 1st November in any year. 



The Report must detail the treatment adopted to fix and retain these in- 

 gi-edients — the materials used for that purpose, and the quantity and 

 cost thereof — comparative analyses of the manure with and without 

 the treatment, and also a statement of the crops grown with manure 

 and without such treatment, must be given by the Reporter. The 

 experiments to have extended over at least two years and crops. 



2. On the results of experiments for ascertaining the com- 

 parative value of Farm-yard Manure obtained from cattle fed 

 upon different varieties of *food, by the application of such 

 manure to farm crops — Twenty Sovereigns. To be lodged by 

 1st November in any year. 



The Report must state the effects produced on two successive crops by the 

 application of manure obtained from cattle fed on different sorts of 

 food, such as turnips and straw alone ; and turnips and straw, with 

 an addition of oil-cake, linseed, bean-meal, grain or other substances. 

 The animals should be as nearly as possible of the same age, weight, 

 condition, and maturity, and each lot should receive daily the same 

 quantity of litter ; and, except as to the difference of food, they must 

 be treated alike. 



The preparation of the manure, by fermentation or otherwise, should be 

 in every respect the same ; and it is desirable that not less than two 

 several experiments be made with each kind, and that the ground to 

 which it is to be applied be as equal as possible in quality and con- 

 dition. 



2. On the hardy and useful Herbaceous Plants of any country, 

 where such climate exists as to induce the belief that the plants 

 may be beneficially introduced into the cultivation of Scotland 

 — The Gold Medal, or Ten Sovereigns. To be lodged by 1st 

 November in any year. 



Attention is particularly directed to the Grains and Grasses of China, 

 Japan, the Islands of the Eastern Archi]ielago, the Himalaya country, 

 the Falkland and South Sea Islands, California, and the high north- 

 western district of America. 



Reporters are required to give the generic and specific names of the 

 plants treated of, with the authority for the same — together with the 

 native names, so far as known ; and to state the elevation of the
