out. It was oltsm'ved that this disoase raroly occurs twice iu the same place 

 consecutively. The worlc in growing sugar-beet seed is described and the re- 

 sults secured in 1904, which are the latest complete returns at hand, are again 

 given. Earlier work in this line has been previously noted (E. S. R., 17, p. 29). 



The sugar industry of Natal, A. N. Pearson and A. Pardy {Natal: Dcpt. 

 Agr. [1906]i pp. 16, figs. 2). — Flistorical notes on the sugar industry are given 

 and its present position and prospects are described. Statistics of imports and 

 exports of sugar and of the production in Natal, and the total consunii)ti(in in 

 South Africa are presented. The varieties of cane generally grown are enumer- 

 ated and briefly noted and analyses of different canes are reported. 



Report on the experimental work of the sugar experiment station for the 

 year 1905, II. II. Corsixs {Rpt. ./(iiiiaica ,^u(/(ir llipt. ,St(i.. lf)0.'). pp. I'lO). — 

 Fertilizer, varietal, selection, and distillery experiments are reported. In the 

 variety tests a yield of nearly 50 tons per acre was secured on 2 acres of seed- 

 ling B-208. In the selection tests this variety also showed the most merit, 

 giving a tonmuge of G5.5 tons of canes per acre. Other varieties worthy of 

 some attention as shown by results secured at Hope are D 1429, B 316, D 109, 

 and D 95. Among Jamaica seedling canes resulting from naturally cross- 

 fertilized seed grown in 1903, No. 30 gave an indicated yield of 74.4 tons per 

 acre, equal to 20,i)55 tons of sucrose, and No. 22 gave a very rich juice contain- 

 ing 2.2 lbs. of sucrose per gallon. 



The bulletin includes a report by C. Allan, fermentation chemist, on the 

 manufacture of Jamaica rum. 



Manurial experiments with sugar cane in the Leeward Islands, 1904-5, 

 F. Watts et al. {Imp. Dcpt. Agr. West Indies, Pamphlet J/.i^ HJiKi, pp. .'il, dgms. 

 .y). — As in former years, the results with plant canes were unfavorable to the 

 use of commercial fertilizers, but with the rattoon crop the use of sulphate of 

 ammonia and nitrate of soda was of benefit. The details of these experiments 

 have been previously given (E. S. R., 17. p. 4r>0). 



Tobacco breeding experiments in Connecticut, A. D. Shamel {Connecticut 

 titate ata. lipt. 190.5, pt. 6, pp. SSl-SJi2, pis. 3, pg. 1). — A general outline of the 

 breeding work carried on, by the station in cooperation with this Department is 

 given and two new varieties produced by hybridization, known as the .Cooley 

 hybrid and the Brewer hybrid, are described in detail. The Cooley hybrid was 

 obtained by CTOssing Havana seed with pollen from plants grown from Flodda 

 Sumatra tobacco seed, and the Brewer hybrid by crossing Connecticut Broadleaf 

 tobacco with Cuban as the mule parent. 



Methods of testing the burning quality of cigar tobacco, W. W. Garner 

 ([/. <S'. Dcpt. Agr., Bur. Plant Indus. Bui. 100, pt. ',. pp. 1.',, pis., 2,' figs. 3.).— Com- 

 plete descriptions are given of the methods. of testing the, burning quality of 

 cigar tobacco by means of different kinds of apparatus, The general results 

 obtained indicated that in order to secure a good burn a heavy filler should be 

 wrapped with a comparatively heavy wrapper and a light-bodied filler with a 

 light-bodied wrajiper, and that of the three components the filler exerts the 

 strongest infiuence on tlit> evenness of the burn. It was also shown that the 

 wrapper and binder strongly infiuence the character of the ash and that the 

 binder very materially affects the ash of the wrapiier. 



Garlicky wheat, J. W. T. Duvel {V. S. Dciit. Agr.. Bur. Plant Indus. Bui. 

 loo, pt. 3, pp. I'l, pis. 2). — Experiments are reported In which garlic was removed 

 from 3 lots of wheat by drying the samples artificially and then removing the 

 garlic liulblets by means of cleaning machinery. The^ .quantity of garlic by 

 veiglit in the 3 lots. A, H. and C, was 2.17. 0.56, and 2.04 per. cent, and the
