Manila hemp culture in Manila, H. Austin [Neie Zealand Dejii. Ayr. Rpt. UtOl, 

 pp. J94-.W0). — This is a report presenting infonnation on the hemp industry in the 

 Philippine Islands. The culture and preparation of the plant is discussed and 

 statistics on the industry from 1S90 to 1900, inclusive, are presented. 



New Zealand hemp (Phormium tenax) (New Zealaud Dept. Ayr. Rpt. 1901, pp. 

 389-294) .—'KeY'^)vi of the commissioner appointed to examine the machines and proc- 

 esses submitted in competition for the V)onuses offered for the encouragement of the 

 New Zealand hemp industry. 



Investigations upon the growth of hops, 1895-1901, A. 1). Hall {.Tour. Bd. 

 Agr. [Ldiiddti], S {190J), No. 4, pp. 4f)9-469). — Growing hops upon string and wire 

 gave better results than the use of poles, an<l cutting away the vine at picking time 

 produced a weakening effect which was noticeable for 2 seasons. The Butcher, 

 umbrella, and Worcester systems of stringing are described. The results of a 5-year 

 test of the different systems did not show a definite advantage in favor of any one 

 system. Stripping the plant of the lower leaves to facilitate spraying caused no loss 

 in the years, of vigorous growth, but in the seasons when the development of the 

 plants was slow they did not recover from the check which they had received from 

 the removal of these leaves. In a cultivation test the discontinuance of all cultiva- 

 tion beyond the destruction of weeds for 7 successive years resulted in no particular 

 reduction of the crop, though perhaps in a slight inferiority in the quality. Deep 

 cultivation at the time the liops began to form induced earlier ripening. 



Several chapters on the lupine, O. Schellenberger {F't'ihl'mg^a Landir. Ztg., 50 

 {1901), Nox. 1-:, pp. 4-'o-4-il; J^i, pp. 463-471; 14, pp- ^^^9-494) .—Thifi article dis- 

 cusses the culture of lupines, their use for soil improvement, and their value for 

 feeding purposes. In considering the culture tlie author speaks of the different 

 varieties, the sensitiveness of the plant to the lime content of the soil, the kind of 

 seed to be used, the effects of inoculation of the soil, and the diseases to which 

 lupines are subject. The discussion of lupines for soil improvement consists of con- 

 cise presentations of the observations made by i)roniinent agriculturists and investi- 

 gators. The consideration of lupines as fodder is devoted mainly to the subject of 

 the harmful alkaloids of the plant and the methods of removing them. Of the dif- 

 ferent kinds the blue lupine is considered of greatest economical value. This species 

 has the best developed root system, and a low alkaloid content, in addition to being 

 one of the best nitrogen gatherers and seed producers. It is also least sensitive to 

 lime and frost. 



A new variety of lupine, A. Sempolovski {Dent. Landw. Prefme, 28 {1901), No. 

 99, p. 821). — A brief note describing the development of a red lupine from a sport 

 of the blue lupine. The new variety has been fixed, and has certain advantages over 

 the mother variety. The results of chemical analyses of the 2 varieties are given. 



Salt for mangels {Agr. Jour. Cape (rood Hojie, 19 ( 1901), No. 9, pp. 590-691).— K 

 brief article on fertilizing the soil for mangels and the use of salt in that connection. 



Culture of oats in 1900, P. P. Deuerain and C. Dupont {Ann. Agron., 27 {1901), 

 No. 11, pp. 551, 552) .-^()i 3 varieties grown at Grignon, Ligowo gave the best yield 

 of grain. This is a yellow variety, and for this reason it is not a favorable sort for 

 the Paris market. 



A new Paspalum ( Queensland Agr. Jour., 9 {1901), No. 5, p. 463). — Under this 

 title a brief note on I', virgatura is given. The species is compared with P. dilatatum. 



Paspalum dilatatum {Agr. Ledger, 1901, No. 1 {Agr. ser., No. 33), pp. 9). — A 

 description of results obtained in India.
