Tho utilization of the free nitrogen of tlic air in agriculou.ro and industry, 

 A. Frank {Chem. Zty., 27 {1903), No. 46, p. 543). — Brief notes on the preparation and 

 on testsof the fertilizing value of the so-called "limenitn^'cn " ('calcium cyanamid), 

 a by-i)roduct of the manufacture of acetylene gas. 



The new fertilizer law {Califortiia Si<i. Circ. [l!:/03], pp. '-). — This law, which 

 went into effect July 1, 1903, reipiires the registration (with director of tlie State 

 experiment station) and labeling of all fertilizing materials selling for !-uS or more per 

 ton. The labels must not only state the percentages but the sources of nitrogen, 

 phosphoric acid (total and available), and jiotash. A registry fee of $50 and a ton- 

 nage tax of 25 cts. are required. The penalty for violation of 'the law is a tine of $50 

 and i-osts for the first offense and $100 and costs for each sul)sequent offense. The 

 act also provides a sum of $1,800 for the equipment of a laboratory for the insjiec- 

 tion work. 



Fertilizers, F. T. Shutt {Catutda. E.rpt. Farm.t Jxpt.^. 1902, pp. 1'>4-15(J). — Analyses 

 of 1 sample of squid, 1 of cajilin, 3 of peat, and 5 of limestones are reported. 



Report on official inspection of commercial fertilizer^ end a2'ricultural 

 chemicals during- the season of 1902, G. A. Goess.maxn {Massnchusett.^ Sta. Rpit. 

 1902, pp. 9-21). — The results of examinations of 451 sampler representing 273 brands 

 are summarized. Tables show the average composition of the different classes of all 

 fertilizers analyzed, and the maximum, minimum, and average composition of si)e- 

 cial crop fertilizers. There was found to be wide variations in the composition of 

 different brands of fertilizers recommended for the same crop. Thus in the tobacco 

 fertilizers examined the nitrogen varied from 1.76 to 6.68 per cent, the total phos- 

 l^horic acid from 3.38 to 13.71 per cent, the available [)hosphoric acid from 2.84 to 

 11.59 per cent, the potash from 1.54 to 14.15 per cent A schedule of trade values of 

 fertilizing constituents and a list of licensed manufacturers and dealers arc given. 



Report on general work in the chemical laboratory, C. A. Goessmann {Mas- 

 s.icliiij<c(ts< Sid. Rpt. 1902, ])p. 22-25). — A brief note on the exanunation of wood ashes 

 and miscellaneous material, including references to work on methods of soil and plant 

 analysis. 



Analyses and valuations of fertilizers, L. A. Voorhees et al. {New Jersey Stas. 

 Rpt. 1902, pp. i7-<S-Z).— This is a reprint of Bulletin 163 of the station (E. S. R., 14, 

 I>. 749) with the addition of a list of manufacturers doing busine.-s in the State and 

 data regarding market prices of fertilizers in New York during 3 ^ ears, 1899-1901, 

 and a compilation showing the average composition of fertilizing materials examined 

 by the staticm since its organization.

 502, jhjx. 33). — This volume forms a part of the Encyclopcdie agricule issued under 

 the direction of (t. Wery. It treats in simple manner of general principles of j)lant 

 nutrition; cal(;areous amendments; farm manures and miscellaneous organic fertiliz- 

 ers; commercial sources of nitrogen, phosi)horic aciil, and potash; fertilizer laws, 

 companies, and valuation; and practical methods of fertilizing cereals, hoed croi)S, 

 leguminous ])]ants, grass lands, oil-producing plants, gardens, and ornamental i)lants. 



Recent progress in the fertilizer industry, R. vo.v GRrEUER {Chem. Ztg., 27 

 {1903), No 40, pp. 479-/fSl). — Reviews briefly g^-.ieral business ])rogress and discusses
