Olive culture and production of olive oil in tlie southern Provinces of 

 Austria, G. .Slaus-Kantschiicder (OlivicuUnra e Produzume d'OIio d'Oliva 

 ncUc Provincir Aleridionali AuHtriachc. S[)(ila1o, AnKtrUi: Tipoc/rafla Sociale 

 ^IKilalina, J!)}//, pp. JfO). — A general descriptive account of olive culture in 

 Aiirious Provinces of littoral Austria, Including statistics of production for the 

 12 years ended in VdVl and notes on destructive insect pests and fungus dis- 

 eases of the olive. 



The loquat, I. J. Condit {California Sta. Bui. 250 (.1915), pp. 251-28Jf, figs. 

 11). — This bulletin treats of the loquat with reference to its botany and 

 nomenclature; geographic distribution; climatic requirements; propagation; 

 .soils and situations; orchard management; harvesting, packing, and marketing; 

 varieties, including descriptions of the more promising forms; and insect pests 

 and diseases. The .subject matter is based upon field observations as well as 

 upon an extensive search of the literature. A bibliography is appended. 



Manurial experiments on cacao, 1913—14, J. de Vkrteuil {Bui. Dept. Agr. 

 Trinidad and, Tohago, IJf {1915), No. 1, pp. 1-16, pis. 8). — A progress report on 

 the manurial experiments which are being conducted on a number of private 

 estates (E. S. R., 30, p. 444). The results obtained during the year ended 

 August 31. 1914, are given for each estate, together with comparative data for 

 the two previous years. 



Data are also given on the natural-yield plats for the last two years. 



The results from these plats continue to indicate that the yield tendencies on 

 any particular plat should be well known before manurial experiments are 

 undertaken. 



The composition of the coffee berry and its relation to the manuring of a 

 coffee estate, R. D. Anstead (Ann. Appl. Biol., 1 (1915), No. 3-.'i. pp. 299- 

 302). — In connection with a study of methods of fertilizing coffee In southern 

 India the author found that under well-established mixed shade .some four 

 tons of air-dry weight of mulch is accumulated per acre each year, containing 

 108 lbs. of nitrogen, 223 lbs. of calcium oxid, 36 lbs. of phosphoric anhydrid. 

 and lis lbs. of potassium oxid. It is concluded that the mulch obtained from 

 shade trees should be taken into account in drawing up a manurial program 

 over a series of years. 



During 1912 analyses were made of coffee berries each month from July to 

 December, or from the time they were quite small to the time when they were 

 ripe and ready to pick' and pulp. The analyses show that there Is a markedly 

 steady increase of potash content throughout the period of growth, from which 

 it is concluded that potash in an available form Is needed all the time. The 

 phosphoric acid content appears to be a constant quantity at first with a maxi- 

 mum about October, after which it declines. This suggests that available phos- 

 phoric acid Is needed chiefly in the beginning of the season. The nitrogen con- 

 tent increases steadily throughout the period of growth and keeps pace with the 

 increase of organic matter. There Is a rapid and regular decrease in the amount 

 of moisture in the berries throughout the period of development. 



A series of manurial experiments based on these analyses has been planned 

 and is now being carried out. 



A new genus, Fortunella, comprising four species of kumquat oranges, 

 W. T. Swingle {Jour. Wash. Acad. 8ci., 5 {1915), No. 5, pp. 165-176, figs. 5).—
