On Plot G common salt was used at the rate of 5 cwts. per 

 acre, and the effect of this dressing- was that 6 cwts. and 88 lbs. 

 less grass per acre was cut on Plot 6 than on the unmanured plots 

 of the field. 



4. Potash salts applied alone had no Ijcneficial effect. 



5. The mixture of superphosphate with potash salts produced a 

 considerable increase. 



G. The experimental field was deficient in lime, and hence 

 tlie application of lime, as also that of bone»dust, had a decidedly 

 beneficial effect. 



Mr. Cadle also tried the same manures on pasture land of 

 rather better description than the field upon which the preceding 

 experiments were made. 



Each experimental plot occupied the space of TiVth of an acre. 

 The manures were sown on the 14th of April, and the grass cut 

 and weighed on the 30th of June. 



The following Table shows the particulars, as regards manures 

 and the effects which they produced : — 



The produce from the two unmanured Plots, Nos. 5 and 10, 

 varied rather more than is desirable in comparative trials. The 

 average produce of these fields is 4 tons 5 cwts. per acre. 



In these experiments the applcation of salt had a decidedly 

 injurious effect upon the grass ; and potash salts also, though in a
