[Experiments with field crops, Barbados, 1908-9], J. R. Bovell (Imp. 

 Dept. Agr. West Indies, Ri)t. Loeul Deiit. Ayr. Barbados, 1908-9, pp. 2-13).— 

 The introduction of sugar canes for planting is noted and brief reports given 

 on cooperative worlv with Sea Island cotton on 9 estates and Sill^et cotton on 

 14 estates. 



The Silliet variety was found growing among plants from seed originally 

 obtained from this Department. Severe drought and the attacks of the 

 scarabee {Cryptorhynchus batata:) prevented entirely satisfactory results with 

 a large number of varieties of sweet potatoes recently obtained from the Penn- 

 sylvania Experiment Station and elsewhere. The maximum yield of 22.240 lbs. 

 per acre was produced by the Southern Queen variety. A report is also given 

 of the results of sowings of seed from the Vincelouian, Six Weeks, and Kala 

 varieties. In 1907, among sweet and bitter varieties of cassava the maximum 

 yields were at the rates of 16.920 and 21,394 lbs. per acre respectively, while 

 in 1908, there were 12,840 and 23.280 lbs. respectively. Twenty-nine varieties 

 of economic Colocasiese introduced from the Porto Rico Station produced re- 

 sults ranging from a total failure to a yield of 3,120 lbs. of tubers per acre. 



[Notes on field crops], R. G. Osfis, J. G. Coubet, and J. C. Pagliery {Estac. 

 Expt. Agron. Cuba Ci>rc. 31, pp. 3-30, figs. 4)- — The writers discuss the cause for 

 the low price of tobacco in Cuba and make suggestions as to methods of culti- 

 vation of .iute, sisal hemp, rultber, coconut palms, and Erythorn.vylon coca. 



Experiment field of the Taganrog Agricultural Society, N. T. Bilinski 

 (In Kratkugho oteheta roznlknov. I desyatll. dyeyateVnostl (1889-1908) op. 

 poJya Taghanroghskagho s.-kh. obshehestva. Taganrog, 1909, pp. 15-.'fl; abs. in 

 Zhur. Opuitn. Agron. (Russ. Jour. Expt. Landw.), 10 (1909), No. 5, pp. 667- 

 673). — The black and early green fallows give better yields of wheat and rye 

 than the late green fallow and most frequently the early green fallow gives the 

 highest yields. Manure produces a greater effect on black fallow than on 

 early green fallow. Rye is more sensitive to manure than wheat.
