best. The author stores in bulk and not in barrels. When the room begins to get 

 dry and dusty the temperature should be lowered, first to 75 or 70°, and then down 

 to below 60°. The temperature preferred in between 55 and 60°. 



The sweet potato, G. L. Sutton (Agr. Gaz. New South Wales, 15 {1904), Nos. 8, 

 pp. 773-780, figs. 5; 9, pp. 881-889, figs. 9).— The culture of the sweet potato is dis- 

 cussed at some length, and the results of experiments in early and late harvesting are 

 summarized in tables. The yield of each variety was very much increased, ami in 

 most cases it almost doubled itself from April 4 to June 22. 



Varieties of tobacco cultivated at the Royal Tobacco Experiment Station 

 in 1903 (II R. Institute Sperimentale per le Coltivazioni dei Tabacchi e l<> Visita del VII 

 Congresso Internazionale D' Agricoltura. Rome: Ministero dette Finanze, 1903, pp. 

 57-60). — A list of 222 varieties of tobacco grown at the station is included in the 

 description of the institution and its special lines of work. 



Wheat culture in the Province of Buenos Ayres, and the varieties of wheat 

 grown in the southern part of this province, C. D. Girola (El cultivo del trigo 

 en la provincia de Buenos Aires y los trigos del sud de la misma. Buenos Ayres: P. 

 Gadola, 1904, pp. 114, figs. 14, maps #). — Statistics on the production of wheat in 

 Argentina, as well as in the province of Buenos Ayres, in 1902-3 are given, and the 

 culture of wheat under Argentine conditions is discussed. One hundred samples, 

 representing the different varieties and sections of the province, are noted in tabular 

 form. The impurities in seed wheat are considered at some length. The principally 

 grown varieties of the country, including 9 bread and 3 durum wheats, are described 

 in detail. 



Report on a test of fourteen varieties of wheat at Garforth, 1903, R. S. 

 Seton ( Yorkshire Col., Leeds, mid East and West Ridings Joint Agr. Council [Pamphlet] 

 34, 1903, pp. 13). — The best yield of grain of good quality was obtained from Carter 

 Royal Prize, which ranked first in quality with Standard Red and Scholey Square- 

 head. The yields of 4 American varieties, Ottawa Percy, Ottawa Red Fife, Ottawa 

 Preston, and Minnesota were unsatisfactory. 



A test of sixteen varieties of wheat at Garforth, R. S. Seton ( Yorkshire Col., 

 Leeds, and East and West Ridings Joint Agr. Council [Pamphlet'] 45, 1904, pp. 13). — 

 In 1904 the Red wheats leading in yield and quality were Browick Grey Chaff, 

 Squarehead Master, Windsor Forest, and Scholey Squarehead; and the White 

 wheats, Hunter White and Carter White Standup. This season a slightly better 

 crop of wheat was grown where the aftermath of the preceding crop of clover was 

 grazed than where it was mown. 



Manure experiments with wheat at Wagga, 1903, F. B. Guthrie and R. 

 Helms (Agr. Gaz. New South Wales, 15 (l-'>04), No. 3, i>p. V14-282, dgm. 1) .— The 

 experiments here reported have been in progress 3 years, and the earlier results have 

 been previously noted (E. S. R., 14, p. 352). The soil under test did not respond to 

 the use of lime, but the use of superphosphate gave good results. Unlimed plats 

 receiving 200 lbs. of superphosphate per acre gave a higher yield than plats receiving 

 in addition 60 lbs. of sulphate of ammonia and 30 lbs. of sulphate of potash. Where 

 superphosphate was used alone 150 lbs. per acre gave the most profitable results. 



The effects of Thomas slag were similar to those obtained from the use of super- 

 phosphate. The largest average yield was obtained on a plat receiving 300 lbs. of 

 Thomas slag, 30 lbs. of sulphate of potash, and 35 lbs. of sulphate of ammonia in 

 1901 and 1902, and 30 lbs. of sulphate of potash alone in 1903. Florida rock phos- 

 phate was more effective than Pacific Island rock phosphate, but much better results 

 than from either one of these substances were obtained from the use of phosphoric 

 acid in the more soluble forms. In a series of tests with complete fertilizer applica- 

 tions the most profitable results were obtained from the use of 30 lbs. of sulphate of 

 ammonia, 100 lbs. of superphosphate, and 15 lbs. of sulphate of potash.
