 1921. — The report covers the period to the end of Oct., 1920. — Experiments with subsoiling as 

 compared with ordinary farm cultivation for sugar cane gave results in favor of subsoiling. 

 Results of experiments on 3 crops subsoiled showed an increase of 9.8 tons of cane and 1.53 

 tons of cane sugar over the amount obtained from 3 crops with ordinary cultivation. With 

 regard to varieties of the Queensland seedlings planted last year at the Mackay Station, 

 Q. 813 and Q. 1092 germinate and grow quickly, while Q. 970, H. Q. 458, and Q. 1121 are 

 fairly good; Q. 1098 is a later-maturing variety. — E. K. Tisdale.

 growth of varieties of sugar cane in the Cairns District of Australia. Badila has given the 

 most satisfactory results; Green Goru (24B) grows well. A small quantity of "Pompey" 

 recently introduced bj' the C. R. S. Co. is promising, judging by its healthy erect appearance 

 and vigorous stool. Shahjahanpur is doing well. This variety is a good striker, has a good 

 root sj'stem, stools well, grows in an erect manner, has a high sugar content, and a high 

 resistance to frost. — E. K. Tisdale.
