they are not yet hoed out. No tloubt I was very unfortunate

4. A sample of " English nitrate of soda" was sent by Mr. 

 Charles Cock, of Hamshead, near Birmingham, who had bought 

 it of Messrs. Padley *Sc Co., of 40, Toll End, Tipton, Staffordshire, 

 at 12/. per ton. 



This so-called " nitrate" yielded on analysis, the following 

 results : — 



Moisture and water of combination 32*55 



*Sulphate of iron 40'98 



Sulphate of liroe '32 



Sulphate of soda and a little chloride of sodium) 99.49 



(common salt) f "" 



Insoluble siliceous matter 3 '73 



100-00 

 *Equal to crystalled sulphate of iron (green vitriol) 74 • 95 



Mr. Cock states, " this order was given because a gentleman 

 (who stated himself to be a partner Avith Padley «Sc Co., and was 

 accompanying their agent soliciting orders) informed me it was 

 better manure, and would produce better results than the imported 

 nitrate under 5 per cent, refraction" [impurity]. The preceding 

 analytical results, however, show that this so-called nitrate is 

 merely salt-cake and green vitriol, and that it possesses no 

 manurial properties whatever. 



5. A sample of oil-cake was sent by Mr. George Liddell, Jun.,

linseed-cakes at 12Z. 15^. per ton, each cake being also branded 

 with a triangle and the initials P. B. 



This cake yielded the following results on analysis : —
