 for several years. — I. S. Cook.

903. Clayton, R. J. B. A memorandum on rice supplies. Bull. Dept. Agric. Federated 

 Malay States 7: 15-27. 1919. — Rice supplies generally; the normal supply and consumption 

 of Malaya; local rice position at present; the effect of the war on rice supplies to Malaya; 

 rice war measures taken in four other countries; the conditions necessary for a large rice 

 production, and rice milling locally are discussed in this article. Several deductions and rec- 

 ommendations relative to increased rice production for Malaya and its relation to the labor 

 situation are given. — /. T. Barrett. 



904. Cockayne, L. An economic investigation of the montane tussock-grassland. New 

 Zealand Jour. Agric. 18: 1-9. 1919. — A sharp division line between the dense forest on the 

 west side of the divide of the Southern Alps and the tussock grassland on the coast side is 

 described by the author. The rainfall ends at the forest line and the eastern grassland con- 

 tains no trees. Most parts of the tussock-grassland will not pasture one sheep to three acres. 

 The montane tussock-grassland is made up of some 210 species of indigenous plants which 

 belong to 39 families and 98 genera. The dominant species is the fescue-tussock (Festuca 

 novae-zealandiae) , while the silver-tussock (Poa caespitosa) dominates the lowland. Methods 

 of improving the pasture land are described, such as burning, surface sowing, and cultivation.

905. Eaton, B. J. Lalang grass as a paper material. Bull. Dept. Agric. Federated Malay 

 States 7: 28-32. 1919. — The value of lalang grass, Imperata arundinacea, as a paper making 

 material is compared with Spanish and Algerian esparto grass. Experiments in pulping 

 showed lalang grass to be inferior to the Spanish but to compare favorably with the Algerian 

 esparto grass. The investigations made indicate the need of information on available are as 

 of raw material, especially lalang, and its cropping possibilities. A brief discussion of the 

 world supply of paper producing materials is included. — J. T. Barrett.

 grandiflorum, natives of Brazil, as forage plants. — M. J. Dorsey. 



907. Piedallu, Andre. Sur le bouturage du Sorgho. [Growing sorghum from cuttings.] 

 Compt. Rend. Agric. France 1919: 76-78. 1919. — By cutting canes into pieces 3 to 4 cm. long 

 each side of a node and removing the sheath by a circular cut just above the node it was pos- 

 sible to grow sorghum from such cuttings. This is of advantage in multiplying desirable sorts 

 without danger of cross pollination. The canes may be kept alive over winter if protected 

 from the cold. — E. A. Bessey. 



908. Ayres, W. E. A bad farm practice. Arkansas Agric. Exp. Sta. Circ. 47. 4 p., 1 pi. 

 1919. — The deterioration in the grade of cotton due to standing in the field is given for three 

 standard varieties. The figures show that a small crop picked early gives better financial 

 returns than a larger crop injured by weather. — John A. Elliott. 



909. Ayres, W. E. Varieties of cotton. Arkansas Agric. Exp. Sta. Bull. 159. 16 p. 

 1919. — Results of tests of 109 varieties and strains in small plots; four regular tests of 25 stand- 

 ard varieties; and more extensive tests of 8 most promising varieties are given for the season 

 of 1918. Fourteen tables show the comparative ranking of the varieties and strains in value 

 of seed cotton and of lint per acre. — John A. Elliott.
