454 PREMIUMS OFFERED BY THE SOCIETY IN 1867. 



The experiment may be conducted either with manure made in the 

 open strawyard, contrasted with that made in covered hammels 

 or boxes, or with manure made in feeding-houses, part of which 

 shall have been placed under cover, and part removed to the 

 open dung-pit, and kept carefully unmixed with any other 

 manure. Preference will be given to experiments embracing 

 both of these modes. The cattle must be fed and littered alike. 

 There must be at least an acre of land experimented on with 

 each sort of manure — the different lots must be manured to the 

 same extent, and be equal in soil and the crops must be accu- 

 rately weighed and measured on two separate portions of each 

 lot, not less than 20 poles. The result, as given by two succes- 

 sive crops, to be reported. 



Reports to be lodged by 1st May in any year. 

 5. AUTUMN MANURING. 



For an approved Eeport on the comparative advantages of 



applying Manure to the stubble in autumn, or in the drills in 



spring, for turnips, potatoes, or beans — Twenty Sovereigns. 



The experiment must extend over two years, and comprise a green 

 crop and a grain crop. It must be conducted on not less than 

 four acres — one-half of which shall be dunged in autumn, and 

 the other in spring, with manure made as nearly as possible in 

 the same way, and of equal quantity and quality. The treat- 

 ment and condition of the land prior to the experiment must be 

 mentioned. 



As the object of this premium is to determine the comparative 

 advantages of autumn manuring, there will be no restriction as 

 to labouring the land, but the reporter must state how that was 

 done on each lot during the experiment, which, if possible, 

 should be repeated in duplicate. 



Reports to be lodged by 1st May, 1868. 



6. IMPROVED VARIETIES OF AGRICULTDRAL PLANTS. 



For an approved Eeport on the means successfully employed 

 for obtaining new and superior varieties, or improved sub- 

 varieties, of any of the cereal grains, grasses, roots, or other agri- 

 cultural plants — The Gold Medal, or Ten Sovereigns. 



It is necessary that the varieties and sub-varieties reported upon 

 shall have been proved capable of reproduction from seed, and 

 also that the relation they bear to others, or well-known sorts, 

 should be stated. The reporter is further requested to mention 

 the effects that he may nave observed produced by different 

 soils, manures, &c, on the plants forming the subjects of re- 

 ports, and how far he may have ascertained such effects to be 

 lasting. 



Should any improved variety reported upon be the result of direct 

 experiment by cross impregnation, involving expense and long- 

 continued attention, a higher premium will be awarded. 



Reports to be lodged by 1st November, 1867.
