 {Bui. Imp. Inst. [So. Kciusington], 12 (WUf), No. 3, pp. J,29-U2) .—This article 

 describes briefly methods of manufacture of flsh manure, cost of fish-reduction 

 plants, kinds and composition of different fish used, and the quality and fer- 

 tilizing value of fish scrap of different kinds. 



Fish meal and fish manure (Jour. Bd. Agr. [London'], 21 (1914), No. 8, pp. 

 688-694)- — This is a brief summaiy of information on this subject. Analyses 

 and methods of use of fish feeds and manure are given. 



Transformation of vinasse into fertilizer, L. Roos (Prog. Agr. et Vit. (Ed. 

 VEst-Ccntre), 35 (1914), No. 4'h PP- W, W^)- — Brief directions are given for 

 mixing this material with other fertilizing substances to produce a balanced 

 fertilizer. 



Hoad sweeping's as manure (Jour. Bd. Agr. [London], 21 (1914), No. 8, p. 

 755). — An analysis is reported which shows road sweepings to be "little if at 

 all richer than ordinary soil, as far as manurial value is concerned." The sam- 

 ples examined contained 0.5 per cent of lime, 0.2 per cent of phosphoric acid, 

 and 0.0S6 per cent of nitrogen. The potash is not reported. 



Fertilizers, R. E. Rose and F. T. Wilson (Fla. Quart. Bui. Agr. Dept., 24 

 (1914), No. 4, pp. 89-114, 126-135, 140-164).— A.n account is given of the fer- 

 tilizer inspection during 1914, including analyses of fertilizers examined, with 

 notes on laws and regulations and valuation of fertilizers. There are also spe- 

 cial articles on home mixing and on commercial fertilizers from the manufac- 

 turer's viewpoint (by Mrs. N. M. G. Prange). 



Analyses of commercial fertilizers, H. E. Curtis (Kentucky Sta. Bui. Ill 

 (1913), tip. 413-591). — Analyses and valuations of 735 brands of commercial 

 fertilizers examined during 1913 are reported. 



Analyses of commercial fertilizers, H. M. STACfKHOUSE, R. N. Beackett, 

 ET AL. (South Carolina Sta. Bui. 117 (1914), pp. 93). — ^This bulletin reports 

 and discusses analyses and valuations of 2,539 samples of commercial fertilizers 

 examined during the season of 1913-14. 



The quality of the fertilizers offered for sale in South Carolina during the sea- 

 son is compared with that of fertilizers examined in previous years. It is 

 shown that 21.85 per cent of the fertilizers examined during 1913-14 were de- 

 ficient in one or more ingredients as compared with 20.6 per cent during the 

 previous year. 



A table is given showing results of determinations of the nitrogen availability 

 of various nitrogenous materials as shown by the Street method. The results 

 show an average availability of at least 85 per cent of the total organic nitrogen 

 and indicate raw materials of good quality. 



Commercial fertilizers in 1913—14, G. S. Fbaps (Texas Sta. Bill. 168, pp. 

 3-34)- — Analyses and valuations of fertilizers inspected during the season of 

 1913-14 are reported, with collateral information regarding fertilizers and fer- 

 tilizer inspection, and a list of registered brands is given. The consumption of 

 fertilizers in the State during the period covered by the inspection is estimated 

 to have been 77,400 tons. 



The South and the fertilizer industry (Manfrs. Rec., 65 (1914), No. 24, pp. 

 4t, 48). — Statistics of the production and consumption of fertilizers in the 

 Southern States as compared with the whole United States are presented and 

 discussed. 



AGRICTJLTURAL BOTANY. 



A botanical lexicon, P. G. Gennadius (Lexikon Phytologikon. Athens, 1914, 

 pp. 16-\-1148). — This lexicon gives the names, habitat, and characteristics of 

 more than 10,000 species of useful and ornamental plants with accounts of their
