1473. Cross, W.E. Recientes resultados con algunos variedades de cafia. [Recent results 

 with cane varieties.] Rev. Indust. y Agric. Tuciiman 10: 74-79. 1919. — A report of 4 years' 

 tests of the varieties S.N. 179, S.N.211, L.CO, and Collyn's seedling is given. All gave low 

 yields as compared with the Javan seedlings and are not frost resistant, consequently are 

 considered unsatisfactory for Tucuman. After 5 years' tests Variety POJ105 is pronounced 

 inferior to POJ36 and 213 in yield and frost and disease resistance. After 3 years' tests 

 D1135 was found less frost resistant than the Javan varieties. Its contained sugar, however, 

 does not invert so rapidly. — John A. Stevenson. 



1474. DoBLAS, Jos6 Herrera. Estudio sobre el maiz. [Maize studies.] Bol. Asoc. 

 Agric. Espafia 12: 94-98. 1920. — This preliminary study of varieties of corn (maize) lists 

 varieties by size of stalk and height of plant. Certain common varieties are compared as to 

 size of grain, weight of ear, and other characters. — John A. Stevenson. 



1475. EspiNOSA, Luis. El mejoramiento de la cana de azucar en Rio Verde, San Luis 

 Potosi. [Improving sugar cane.] Rev. Agric. [Mexico] 5: 810-816. 9 fig. 1921. — Brief 

 descriptions and cultural directions are given of certain cane varieties, including Red Assam, 

 Hambleden seedling, Hawaii 16 and 27, Lahaina, Morada, and Ribbon. — John A. Stevenson. 



1476. Fawcett, G. L. La obtencion de canas de semilla producida en la Argentina. [Pro- 

 duction of sugar cane seedlings from Argentina seed.] Rev. Indust. y Agric. Tucuman 10: 

 31-41. 13 fig. 1919. — Until 1919 attempts by experiment station workers to obtain fertile 

 seed for seedling production in Tucuman failed. This is thought to be due to weather con- 

 ditions. The flowering panicles of the native cane variety (criolla), Kavangire, and certain 

 of the Javan varieties are described. — John A. Stevenson. 



1477. Fawcett, G. L. Notas adicionales sobre las cafias crioUas. [Further notes on 

 native canes.] Rev. Indust. y Agric. Tucuman 10: 169-175. 3 fig. 1920. — Notes on the origin 

 and distinguishing characters of native cane varieties in Tucuman are given. Pubescence, 

 particularly of the buds, is considered. The prevalence of mutations in the varieties Rayada 

 (striped), Morada (dark red), and Blanca (white), in comparison with the same or similar 

 varieties in Java and elsewhere, is discussed. The author holds that the dark red cane has 

 given rise to the striped and the striped to the white, but that the reverse has not occurred. 

 Dr. Jeswiet of Java disagrees in part with this conclusion. — John A. Stevenson. 



1478. Ferreira, Emilio I. El algodonero. [The cotton plant.] Bol. Ministerio Agric. 

 Naci6n [Argentina] 25: 388—103. 1921. — This is a discussion of cotton culture and the varieties 

 adapted to Argentina, seed selection, planting, cultivation, harvesting, and ginning. — 

 John A. Stevenson. 



1479. Gasser, G. W. Report of the work at Rampert station. Rept. Alaska Agric. Exp. 

 Sta. 1918: 33-54. PI. 3-4. 1920. — Among important facts recorded are: Medicago falcata 

 is the only alfalfa perfectly hardy; Vicia cracca scored its first failure, after doing well in 

 previous years; Trijolium lupinaster suffered winter injury for the first time since seeded in 

 1914; field peas were a failure on very dry ground, as only 1.6 inches of rain fell during IMay, 

 June, and July, — lower-lying ground produced some peas; winter wheat and 1 variety of rj'e 

 were failures, but 2 varieties of rye wintered almost perfectly. In the grain-breeding work 

 all plats, except for a few increase plats of barlej^, oats, and wheat, were head to row, with 

 2 drill-row plats; earliest barley and oats ripened in 79 days from date of seeding, earliest 

 wheat in 84 days. Hemp made a short spindling growth; flax ripened 10 per cent of seed when 

 cut Sept. 7; some seed of Jersey Wakefield cabbage was produced, but carrot seed failed to 

 ripen; potatoes grown in pens or cribs produced only I as much as in the garden, where 2-2.8 

 pounds per hill were produced; peas, celerj^ beans, cabbage, cauliflower, brussels sprouts, 

 kohl-rabi, chard, beets, sugar beets, and carrots were grown successfully in the garden, while 

 cucumbers, muskmelons, egg plant, and peppers were grown in hotbeds; tomatoes were grown 

 in the greenhouse, and a few ripened outside; strawberries winter-killed to some extent; 

 flowers and house plants were successfully grown. — /. P. Anderson.
