Analyses of commercial fertilizers, P. Schweitzer and R. M. Bird 

 Sta. Bui. 66, pp. 8). — This bulletin contains a report of analyses of commercial fer- 

 tilizers collected during the fall of 19Q4 and the spring of 1905, as well as a financial 

 statement of the receipts and disbursements of the fertilizer control fund for the 

 year ended December 31, 1904. 



Analyses of commercial fertilizers, P. Schweitzer and R. M. Bird (Missouri 

 Sta. BuJ. 70, pp. 11). — This bulletin reports analyses of commercial fertilizers col- 

 lected during the fall of 1905, and gives a statement of receipts and disbursements of 

 the fertilizer control fund for the year ended December 31, 1905. 



Commercial fertilizers, W. W. Miller and N. W. Lord (Offic. Rpt. Sec. Ohio 

 />'</. Agr. on Com. Ferts., 1905, pp. 100). — The results of inspection of fertilizers in 

 Ohio during the year 1905 are given, with statements regarding the fertilizer control 

 and the valuation of fertilizers, and the text of the State fertilizer law. 



Licensed commercial fertilizers, 1906, F. W. Woi.l and G. A. Olson ( Wis- 

 consin Sta. Bui. 134, pp. 1-17, 24-26). — Analyses of 22 brands of fertilizers licensed 

 f#r sale in Wisconsin during 1906 are reported, with a brief general discussion on 

 the purchase, valuation, and use of commercial fertilizers, and the text of the State 

 fertilizer law. 



Fertilizers in Japan (Bd. Trade Jour. [Gt. Brit.~\, 1906, Jan. 4; abs. in Jour. Soc. 

 Chern. Indus., 25 (1906), No. 2, p. 84). — Statistics are given showing the extent and 

 increase of use of fertilizers in Japan, especially of oil cakes. 



The value of the fertilizers imported into Japan during the first 6 months of 1905 

 is reported to have been 12,976,352 yen (§6,462,223.30). Of this amount 7,265,109 yen 

 l >:'.. til 8,024. 28) was paid for oil cake, 638,217 yen ($317,832.07) for ammonium sulphate, 

 1,179,304 yen ($587,293.39) for calcium phosphate, and 636,997 yen ($317,224.51) 

 for sodium nitrate. The oil cake comes from China, one-third of the nitrate 

 from the United States, and the remainder from Chile and various other countries, 

 the calcium phosphate and ammonium sulphate from the United Kingdom. There 

 are several chemical factories at Osaka which produce fertilizers, especially ammonium 

 sulphate. 



Artificial fertilizers, P. G. Wicken (Jour. Dept. Agr. West. Aust., 12 (1905), No. 1, 

 pp. 7-18). — This article discusses especially the prices and value of the fertilizing 

 materials available in West Australia, and gives formulas for fertilizer mixtures for 

 various kinds of crops, with directions for their application. The draft of various 

 crops on the fertilizer constituents of the soil is also explained. 



AGRICULTURAL BOTANY. 



Plant breeding-, L. H. Bailey (New York and London: The Macmillan Co., 1906, 

 pp. NIY-\-483, figs. 43). — This is a fourth edition of the author's work on plant 

 breeding, which first appeared in 1895 (E. S. R., 7, p. 562). 



The most marked changes in this work are to be found in chapter IV, which has 

 been wholly rewritten and w T hich gives a resume of the investigations of de Vries, 

 Mendel, and others, and in chapter V, which gives accounts of current plant-breeding 

 practice. This last chapter summarizes the w T ork of Burbank and Keeney, and the 

 investigations of the experiment stations and of this Department along this line. A 

 chronological bibliography of references to such literature as English-speaking horti- 

 culturists would be most likely to find completes the volume. The bibliography 

 embraces something over 100 pages and is brought down to 1905. 



On the correlation between calcium salts and the assimilation of nitrate 

 nitrogen, V. Y. Yermakov (Zhur. Opuitn. Agron. (Russ. Jour. Expt. Landw.), 6 

 (1905), No. 4, pp. 403-431).— The formation of ammonia and oxalic acid when nitric 

 acid acts on glucose suggested to the author the possibility of a similar reaction tak- 

 ing place in plants during the assimilation of nitrate nitrogen, whereby the ammonia
