will' answer). Empty the manure out of one of the bags into a 

 basin, add to it some sand or loam slightly damped, aud mix the 

 two carefully with the hand, turning them over several times so 

 as to get them uniformly mixed. From the nature of the 

 manures it will be found that there are great differences in the 

 bulks, and for this reason the quantity of sand used must be so 

 adjusted as to bring all to the same bulk in order to secure 

 accuracy in sowing. 



16. Carefully preserve the whole of the bags, and return them 

 at your convenience to 15 Shuttle Street. 



17. Three pounds of Aberdeen yellow turnip seed are sent 

 with each lot of manure, being a quantity sufficient to sow one 

 acre. 



18. It is desirable that the crop should be singled to a uniform 

 distance of 10 inches. 



19. Instructions for weighing the crop, with schedules for 

 recording the results, shall be sent to each experimenter at a 

 later period. 



As regards the experimenters of this season, we have been so 

 fortunate as to retain the assistance of most of the gentlemen to 

 whose good work the Society was so much indebted during the 

 previous year. Some gentlemen, however, were prevented by 

 circumstances from giving their services this year, and their 

 places have been filled up by others solicited by the chairmen of 

 the local committees, who are the same as last year — viz., Mr 

 Hope, Fenton Barns ; Mr Koberton, Ladyrig ; Mr Goodlet, Bol- 

 shan; and MrDrennan, Holmston. The experimenters as finally 

 arranged were : —
