On the Nitrate of Scda. 



carefully kept separate, and thrashed on the 22nd of September : each 

 land contained 605 square yards, or one-eighth of an acre : the result 

 was as follows : — 



Yds. Stones. Lb. Imp. Bushel. Stones. Lb. 



605 undressed land 25 12 of sti-aw and 6^ of corn, which weighed 16 12 

 605 dressed land .38 10 of straw and 8 of corn, which weighed 22 5 



This calculated by the acre gives — 



Cwt. Qr. Lb. Bushels. Cwt. Qr. Lb. 



Dressed Land 38 2 24 of straw and 64 of oats, net weight 22 1 12 

 Undressed Land 25 3 12 of straw and 481 of oats, net weight 16 3 12 



12 3 12 151 * 5 2 0 



From the above results it appears that the dressed land produced the 

 heaviest corn by a very little ; but had it not been laid with the weather, 

 it would doubtless have been heavier. 



By the above calculation I consider the nitrate paid me very well, for 

 supposing straw at 30^. per ton and oats at 1^. per stone, there will be 

 a clear profit (after deducting 19s. 6c/. for the nitrate of soda, 2s. 6d. 

 carriage, and 2jc?. applying on ground) of 21. Is. 3^d. 



I made several trials of the nitrate of soda on a light brown soil, on 

 limestone, which in appearance answered even better than the above. 

 I applied it across a 6-acre field of oats, which grew above the rest of 

 the field at least 10 inches. I also tried it on pasture (light soil), and 

 the luxuriance was very great in appearance till the latter end of July, 

 when the herbage was no better than in the rest of the field. The cattle 

 kept the part dressed very bare of food, and appeared exceedingly fond 

 of it. A friend of mine also used a few cwts. on a gritstone soil, 

 which answered very well for both grass and turnips, as well as corn, 

 but as he did not measure or weigh, nothing more definite can be said 

 of it.

Experiments with Nitrate of Soda on the Duke of Norfolk's 

 Estate in Svffolk.* Communicated by the Rev. W. L. Rham. 



One hundred and fifty pounds weight of nitrate of soda per acre was 

 sown on part of a piece of clover ; the remaining part of the field was 

 not manured. 



The clover was cut on the 6th of July; on the 11th, when in good 

 state to cock or cart, an equal portion of the field of clover was 

 weighed : —
