581. Anonymous. Selection of canes for planting. Australian Sugar Jour. 12:382- 

 1920. — A system of growing sugar cane for seed purposes has been started at the Kairi 

 Experiment Station, on the Atherton Tableland. This has been done in an endeavor to 

 preserve the high quality and heavy tonnage of the Badila sugar cane, the Rose Bamboo, 

 Meera, and other of the older varieties of cane. — C. Rumhold.

 4 fig. 1919. — The bulletin presents, in the first, part a brief discussion and history of the cul- 

 tivated sunflower (Helianthus annuus) and gives the results of tests on yields and methods 

 of growing and feeding sunflowers, as applied to Montana. The second part of the bulletin, 

 pages 13-29, discusses the use of sunflowers as a silage crop. — H. E. Morris. 



584. Atkinson, E. H. Weeds and their identification. New Zealand Jour. Agric. 20: 

 299-301. PI. I. 1920. — Lantana camara L. is described. It has been present in New Zea- 

 land for twenty-five years, but still seems to be confined to one rather small section. The 

 fruit is reported to have made children sick, but it is not believed to be injurious to live 

 stock. — A'. J. Giddings. 



585. Baird, W. p. Corn experiments at the Judith Basin substation. Montana Agric. 

 Exp. Sta. Bull. 132:3-24. 9 fig. 1919.— The bulletin reports experiments in growing corn 

 in rotation and by different tillage methods. No varieties have been found that can be 

 depended on to mature a grain crop, but a good quality of fodder corn is produced. Yields 

 of corn were larger than those of alfalfa, brome grass, or red clover. Yields of oats, spring 

 wheat, and barley have in all cases been higher after corn, and have averaged about the 

 same yields as when these crops were grown on summer-fallowed land. — H. E. Morris. 



586. Barber, C. H. The growth of the sugar cane. On tillering. Internat. Sugar 

 Journal 22:495-498. 1920.— Tillering, the inherent branching capacity of the cane, differs 

 a good deal according to the variety and especially the group of cane grown. There are a 

 number of factors which limit the power of a cane variety to produce its full yield. The 

 external influences are light available, moisture in the soil, character of the soil, and amount 

 of manure applied. As a general rule in cultivated canes, thickness and tillering-power 

 are inversely related. The inherent character of the groups, of course, must not be neglected.
