The leading varieties In seed production Included Blackbeauty, Haberlandt, 

 Mammoth fellow, Sherwood, Tokyo, Bollybrook, and Blloxl. The proportions 

 of straw ami grain in the yield varied, ranging from 18 per ceni <>f grain for 

 Barchet to 42 per cent for Blackbeanty. The time required for the best sorts 

 to mature seed varied from lis to 135 days, in i!H7, iii cooperation with the 

 U. S. Department of Agriculture, 41 varieties and strains wen' grown f<>r 

 seed, all of which yielded less than Mammoth Yellow. Considerable varia- 

 tion in the fat and protein content of the different varieties was also noted 



Average yields of hay were secured ranging from 2,832 to 5,608 lbs. per acre. 

 The growing period for 10 varieties varied from 85 to 1112 days. Ebony, Solly- 

 hrook, Wilson, and Otootan are said to produce a good quality of hay, while 

 Mammoth Yellow and Blloxi are somewhat woody. 



A mixture of soy heans and cowpeas seeded broadcast at the rate of 5 pk. 

 each produced about 1.25 tons of excellent hay per acre. Reducing the 

 seeding rate to 48 lbs. per acre did not affect the yield, while soy beans seeded 

 at the rate of 64 lbs. produced only about half as much as cowpeas seeded 

 alone. 



Cotton grown after soy beans, cowpeas, and corn produced 1,459, 1,426, and 

 1,141 lbs. of seed cotton per acre, respectively. Mixtures of Red Rust Proof 

 oats and crimson clover, Blue Stem wheat and crimson clover, and crimson 

 clover alone following the crops noted above produced 4,249, 4,208, and 3,391 

 lbs. of hay per acre, respectively. Winter oats following soy beans shewed an 

 increased yield of 173 per cent over that following corn. The average yields 

 of grain for an 8-year period amounted to 1,677 lbs. of corn per acre, 611 lbs. 

 of cowpeas, and 721 lbs. of soy beans. 



Rabbits, nematodes, wilt, and root rot are said to be the most common 

 enemies of soy beans. 



Brief descriptions are presented of 22 leading varieties.

Studies in Indian sugar canes. — III, The classification of Indian canes 

 with special reference to the Saretha and Sunnabile groups, 0. A I'vkkeb 

 (Mem. Dept. Agr. India, Bot. Ser., 9 (1918), No. 4, pp. 129-218, pit. 11, fig». ..'>.— 

 The author presents a further contribution to the subject (E. S. R.. 33. p. 885; 

 36, p. 737), comprising a report on a classification of heretofore unidentified 

 Indigenous sugar cane varieties grown at the cane-breeding station, Oolmbatore, 

 Two additional groups of varieties have been recognized and are designated 

 as the Saretha and the Sunnabile, respectively, these being the names of 

 typical varieties in each group. 



Observations were made during the 1916 and 1917 cropping si asons. The 

 work as presented embraces a general list of the characters dealt with fol- 

 lowed by a summary in tabular form of the prbicipal differences noted be- 

 tween the two groups; notes on the dissection of stools as demonstrating the 

 thickness of early and late canes and the relative systems of branching in the 

 groups; outlines of a method for constructing an ideal cane for a variety or 

 group by averaging measurements of the lengths of organs at successive joints; 

 and a detailed list of the characters in which differences were observed with 

 tables of measurements for the individual varieties in each group. 



It is stated that the data upon which the classification Is based also prt 

 information regarding the lines of evolution among certain cultivated canes, 

 and that marked progress has been made In tracing the origin from the wild 

 ancestor. A series of connecting links between the cultivated Si>rts and wild 

 Saccharums now growing In India are believed to have been established.
