118 Report of Experiments on the Growth of Wheat. 
In tho sixteenth and succeeding seasons the sulphato of potass 
was reduced to 200 lbs., and the sulphato of soda to 100 lbs. 
Plot 21. — Mixed mineral manure, as Plots 5, and 100 lbs. muriate of 
ammonia. 
Plot 22. — Mixed mineral manure, as Plots 5, and 100 lbs. sulphato of 
ammonia. 
Plots 6 (a and b). — Mixed mineral manure, as Plots 5, and 100 lbs. each, 
sulphate and muriate of ammonia. 
Plots 7 (a and b). — Mixed mineral manure, as Plots 5, and 200 lbs. each, 
sulphate and muriate of ammonia. 
Plots 8 (a and b).— Mixed mineral manure, as Plots 5, and 300 lbs. each, 
sulphate and muriate of ammonia. 
Plots 16 (a and b). — Mixed mineral manure, as Plots 5, and 400 lbs. 
each, sulphate and muriate of ammonia. 
Plots 17 (a and b).— 200 lbs. each, sulphate aud muriate of ammonia 
in the ninth and every alternate season ; and mixed mineral manure, 
as Plots 5, in every intermediate season. 
Plots 18 (a and b.) — Mixed mineral manure, as Plots 5, in the ninth 
and every alternate season ; and 200 lbs. eacb, sulphate and muriate 
of ammonia in every intermediate season. 
Plot 10 a. — 200 lbs. each, sulphate and muriate of ammonia (ammonia- 
salt alone also in the seven preceding seasons, succeeding silicate 
of potass and superphosphate of lime in the first season). 
Plot 10 b. — 200 lbs. each, sulphate and muriate of ammonia (the same 
in the eighth season, mixed mineral manure in the seventh, ammonia- 
salts in the sixth, ammonia-salts and mixed mineral manure in tho 
fifth, ammonia-salts in the fourth, unmanured in the third, ammonia- 
salts in the second, and silicate of potass and superphosphate of 
lime in the first season). 
Plots 11 (a and b). — 200 lbs. each, sulphate and muriate of ammonia, 
and superphosphate of lime as Plots 5. 
Plots 12 (a and b). — 200 lbs. each, sulphate and muriate of ammonia, 
superphosphate of lime as Plots 5, and 550 lbs. sidphate of soda 
(reduced to 366 lbs. in the sixteenth and subsequent seasons). 
Plots 13 (a and b). — 200 lbs. each, sulphate and muriate of ammonia, 
superphosphate of lime as Plots 5, and 300 lbs. sulphato of potass 
(reduced to 200 lbs. in the sixteenth and subsequent seasons). 
Plots 14 (a and b). — 200 lbs. each, sulphate and muriate of ammonia, 
superphosphate of lime as Plots 5, and 420 lbs. sulphate of magnesia 
(reduced to 280 lbs. in the sixteenth and subsequent seasons). 
Plot 9 a. — 550 lbs. nitrate of soda, and mixed mineral manure as 
Plots 5 (only 475 lbs. nitrate in the ninth, and 275 lbs. in the 
tenth and eleventh seasons, and no mineral manure in the ninth, 
tenth, and eleventh seasons, commencing only in the twelfth). 
Plot 0 b. — 550 lbs. nitrate of soda alone (only 475 lbs. in the ninth 
season). 
Plot 15 a. — Mixed mineral manure, as Plots 5 (but with 200 lbs. 
hydrochloric instead of 150 lbs. sulphuric acid), and 400 lbs. 
sulphate of ammonia. 
Plot 15 b. — Mixed mineral manure, as Plots 5 (but with 200 lbs.
