860. Anonymous. Cane arrowing. [Rev. of an interview of H. T. Easterby, in the "Mer- 

 cury," an Australian newspaper.] Australian Sugar Jour. 13: 283. 1921. — The conditions 

 which produce arrowing, or flowering of the cane plant, in the cooler cane-growing areas are not 

 well understood but are mostly attributable to climatic factors. Experiments at the Sugar 

 Experiment Station at Mackay with arrowed and non-arrowed plants of the same variety and 

 age gave a slight yield in favor of the arrowed plants in both the plant and first rattoon crops. 

 A higher percentage of sugar is extracted from the cane in the Ingham-Mourilyan district, 

 where arrowing is usual, than anywhere else in Queensland, except the Lower Burdekin; 

 consequently arrowing conditions need not be greatly feared. Any decrease in the sugar con- 

 tent of the cane in 1921 will probably be due to the great amount of rain late in the season. — 

 C. Rumbold.
