16. Deerr, Noel. The origin of the Uba and Cavengerie canes. Internat. Sugar Jour. 

 22:650-681. 1920.— Through correspondence with Daniel de Pass lately of the Reunion 

 Esta-e in Natal with regard to the origin of the Uba cane, it appears that the firm of de Pass 

 imported cane from both India and Mauritius to Natal. A cane believed by Mr. de Pass, 

 Sen., to have come from India was planted by him. The label had been damaged, only the 

 letters "Uba" were plain and at the time it was thought the letters represented but a part of 

 the name. As the firm of de Pass obtained cane from India and Mauritius at nearly the same 

 time, it it conceivable that the package thought to have come from India really came 

 from Mauritius. The author then suggests a possible sequence of events covering the origin 

 of the Uba cane, if it came from Mauritius. Cavengerie cane originated in New Caledonia 

 and was taken to Mauritius. It was brought into Porto Rico in 1872; was taken to Brazil 

 where it was called Louzier and under this name was sent to Argentina. It is also grown 

 in Australia, where in some places it is misnamed Cheribon. A similar name, Kavangire, 

 has been applied to the Uba cane, but where and how the name Kavangire was transferred 

 to the Uba cane is not known. — C. Rumhold. 



17. Faber, Harald. The growing of forage crops on the dairy farms of Denmark. Scot- 

 tish Jour. Agric. 3: 16-26. 1920.— The expansion of the forage crops of Denmark was occa- 

 sioned by the quantities of cheap grain which came to Europe in the latter part of the nine- 

 teenth century. The acreage in roots increased from 6000 in 1861 to 678,000 in 1919. At 

 present 1,900,000 acres are in grass and clover under rotation while 1,100,000 acres are in 

 permanent grass. All the forage roots and most of the grasses are grown from high-yielding 

 strains of Danish seed. — H. V. Harlan. 



18. FiNDLAY, William M. Potato synonyms. Scottish Jour. Agric. 3: 202-207. 1920.— 

 The varieties of potatoes reported were grown at the experimental farm of the North of 

 Scotland College of Agriculture, at Craibstone. The synonyms are not necessarily ones of 

 identical strain but of almost identical type. Fifteen varieties of the Duke of York, 32 of 

 British Queen, 28 of Abundance, and 72 of "Up to date" are reported. The yields recorded 

 show that in most instances the synonymous variety differed more from the type variety in 

 the 1st and 2nd crops after it was acquired than was the case later. — H. V. Harlan. 



19. Gemmill, J. F. Wheat-bulb disease. Nature 106: 148. 1920.— The paper refers to 

 infection by larvae of a fly {Hylemyia coarctata) which caused much damage in the east of 

 Scotland during the past season. The eggs are laid among root crops, especially potatoes, 

 and on fallow ground, so that the recommendations of recent German investigators that 

 wheat should be preceded by root crops is based on error. — 0. A. Stevens. 



20. Gessner, E. R. Sugar cane farming for the beginner. [Reprint of Winklespruit 

 Government Experiment Station Bulletin issued in 1919.] South African Sugar Jour. 4: 

 1137-1195. 1920. — A practical account of sugar cane farming in South Africa is given with a 

 discussion of climate, soil, field operations, varieties, and harvesting. The cane belt in 

 South Africa is a narrow strip of country from Port Shepstone on the south to just beyond 

 Samkele on the north. The climate of Zululand is more suited to cane growing than is that 

 of Natal, owing to its greater humidity and heat. The two most valuable types of soil in the 

 cane area are Red Hillside and Black Vlei. The former is more readily brought into good 

 condition for planting — the latter requires more experience in handling. There is a 3rd soil type 

 found along the river bank and flats, liable to flooding by heavy rains, but of excellent produc- 

 tivity when the weather conditions are favorable. From experiments at the Winklespruit
