station it v/as found that cane 12 months old is best for planting. Middle and tip portions 

 of cane give better growth than butts for both the Uba, the standard variety, and the Agual, a 

 recent introduction from India. Uba has long proved best adapted to local conditions. In 

 Natal and Zululand fertile seed has never been produced by this variety, which makes crossing 

 with Uba cane impossible in this section. Soft canes are seldom grown in this country. 

 Several varieties have been tested at the experiment station and work is being continued 

 with the more promising ones. — E. Koch Tisdale. 



21. Hansen, Albert A. Chicory, control and eradication. U. S. Dept. Agric. Dept. 

 Circ. 108. 2-4- Fig. 1. 1920. — Chicory, a troublesome weed in pastures, meadows, and 

 along roadsides in the northern half of the United States, is described. Its distribution and 

 uses are given. Eradication and control measures are discussed. — L. R. Hesler. 



22. Hansen, Albert A. The hawkweeds or paintbrushes. U. S. Dept. Agric. Dept. 

 Circ. 130. 3-7.' Fig. 1-2. 1920. — Three noxious hawkweeds are described, namely, orange 

 hawkweed {Hieracium aurantiacwn) , king-devil {H . florentinum) , and yellow field hawkweed 

 (H. pratense). Eradication and precautionary measures are given. — L. R. Hesler. 



23. Haywood, A. H. Saccaline at Wollongbar experiment farm. Agric. Gaz. New South 

 Wales 29:886-887. 1 fig. 1918. — Saccaline, recently introduced from Victoria, is a local 

 name for a strain of sweet sorghum (Andropogon sorgJiwn), which seems to have developed 

 perennial hab'ts. It attains a height of 12 feet, stools well, matures seed freely, has the 

 ratooning habit and is considered more valuable than other sorghums. One grower is said 

 to have obtained 9 cuttings. Chemical analysis is given. — L. R. Waldron.

 U. S. Dept. Agric. Dept. Circ. 136. 3-Sl. Fig. 1-3. 1920.— The report gives yields and 

 market value of alfalfa, barley, oats, wheat, potatoes, hay, pasture, garden and miscel- 

 laneous crops; variety tests of wheat, barley, and potatoes; tests of horticultural crops, 

 including tomatoes and sweet corn; blossoming date for varieties of apples, pears, plums, 

 and prunes; and concludes with an account of experiments made in the reclamation of alkali 

 soil. — L. R. Hesler. 



25. IvERSEN, K. Lokale Markfors0g i Danmark. [Local field experiments in Denmark.] 

 Nordisk Jordbrugsforskning (K0benhavn) 1920: 102-120. 1920. — The author summarizes 

 and discusses experiments carried on with fertilizers, high yielding strains, seed disinfection 

 and potato sprayings by a large number of local experimenters and by farmers' unions during 

 the years 1893-1919. The increased crop yields are compared with the amount of artificial 

 fertilizers applied and with the varying costs of the fertilizers and treatments. — Ernst Gram. 



26. Johnson, E. Behavior of inoculated legimiinous seed. Monthly Bull. Dept. Agric. 

 California 9: 31-36. 1920. — Nitrogen-fixing bacteria exist in several forms, i.e., bacteria from 

 certain legumes will not inoculate certain other legumes. Legumes are divided into 14 groups. 

 The organisms from the nodules of any legume can inoculate any other legume within the 

 same group onljr. In the field, the organisms can withstand any degree of acidity or alka- 

 linity that the corresponding legume can endure. Inoculation does not render the plant 

 immune to any of the diseases to which it is susceptible, does not increase its resistance to 

 frost, sunburn, alkali, acidity, drought or excess moisture, and does not in any way alter its 

 habit of growth. — E. L. Overholser.

 giving the results of tests. — A. L. Pieters.
