of plantin": small amounts of seeds are stated. The history, principal charac- 

 ters, and more important facts relating to 2 select strains of the Triumph 

 variety; the Columbia, a long-stapled upland variety; the Dillon, a wilt-resist- 

 ant variety; the Sistrunk, a select strain ; and the Trook cotton are given. 



[Fiber tests], H. G. Havik (Jaarh. Dcpt. Landb. Nederhind. Indie, 1908, pp. 

 319-333, pis. 2). — These pages state the results of tests of the breaking strength 

 of fibers of numerous varieties of cotton, sisal hemp, and Manila hemp. Chem- 

 ical analyses are also given. 



On the value of the male hop, E. S. Salmon and A. Amos (Jour. Southeast. 

 Agr. Col. Wye, 1908, No. 11, pp. 36',-391, pis. 11, figs. 8; County Councils Kent 

 and Surrey, Southeast. Agr. Col. Wye [Leaflet, 1908], pp. 26, pis. 11, figs. 8; 

 Jour. Inst. Breiv., U, (1908), No. 4, pp. 309-331, pis. 12, figs. S).— The investiga- 

 tions of the authors show that only when a certain number of the bracteoles 

 bear seeds will the hops " grow out " properly, and therefore, it is desirable that 

 the flower at the base of each bracteole be pollenized. Burrs enclosed through- 

 out in paper bags in no case produced seeds, but burrs from which the bag 

 was removed for a moment and pollen dust applied with a paint brush pro- 

 duced full-seeded well-grown hops. 



The number of seeded bracteoles on the hops studied varied from 3 to 16, 

 the number of seedless bracteoles from 10 to 32, and the total number from 

 14 to 30, while the length per hop varied from f to 14 in. The hojis having the 

 greatest number of seeds were the longe.'^t. except in one instance. 



One-seventh acre of seeded white bine hops produced 88* bu. as compared 

 with 42J bu. of seedless hops produced on an equal area in the same garden. 

 The seeded hops were valued at 84 to 95s. per bushel and the seedless at 54 to 

 70s. The added value due to fertilization was about £24 10s. per acre. As 

 the official opinion on the Continent seems to be that the i)resence of the male 

 hop is injurious, it is suggested that these observations may not apply with 

 equal force to white, green, and red bine varieties. 



Seeded hops bearing an average of 9.5 seeds per hop contained 15 per cent 

 of resin and produced S| cwt. per acre, or 147 lbs. of resin, while seedless hops 

 averaging 0.5 of 1 seed per hop contained 17.2 per cent of resins and pro- 

 duced, under similar circumstances, 4f cwt. per acre, or 92 lbs. of resin. 



Sixty-Day and Kherson oats, C. W. Warburton (TJ. S. Dcpt. Agr., Farmers' 

 Hid. 39o, pp. 21, figs. 5). — This discusses the need for early oats, states the 

 history of Kherson and Sixty-Day oats, describes them, and discusses their char- 

 acters and adaptability to different sections of the country. The results ob- 

 tained by the state experiment stations are presented as compiled from bulletins, 

 reports, and unpublished correspondence. 



The Sixty-Day and Kherson varieties represent the most satisfactory type of 

 eai-ly oats. They are desirable because of their heavy yield, low proportion of 

 hull, and resistance to lodging, and their chief defects are the small size and 

 yellow color of the berry. They have given the best results in the corn belt and 

 on the dry farming region but larger, later varieties yield more heavily under 

 irrigation and in the Northern States. 



The present status of investigations of varieties of sugar beets, T. Remy 

 and E. Zimmermann (BI. Znckrrriihenhnu. 11 (1910). Nos. 3, pp. Jfl-^'^; -'/, PP- 

 51-10; 5, pp. 77-cS5).— The author presents in tabular form the results of the 

 investigations of numerous experimenters, the yield of beets and of sugar per 

 hectare, and tho jiercentage of sugar jiroduced by each variety. 



The sig'nificance of number of embryos and size of beet seed-balls, P. 

 Schubaut iCenthl. Zuckerindus., 18 (1909), No. 13, pp. 362-361 ehart i).— The 

 author separated 1 kg. of beet seed into the portions that would pass through a 

 sieve with meshes of li mm., 2 nun., 24 mm., and so on to 5 mm. Of those
