1142 EXPERIMENT STATION RECORD. 



"It is quite evident that the subject of plant inoculation in this country has not 

 yet passed the experimental stage, and more work is required before one can feel at 

 all justified in recommending either method for adoption on a field scale; neverthe- 

 less, the positive results obtained may lead farmers to hope that in the future benefit 

 may be derived, in some instances at least, from the treatment of the soil or the seed 

 before sowing, with inoculating materials preparatory to growing leguminous crops." 



The fixation of atmospheric nitrogen (Engineering [London], 81 (1906), No. 

 2090, pp. 89, 90; Sci. Amer. Sap., 61 (1906), No. 1573, pp. 25205-25207).— -This is 

 a review of investigations on this subject, including in some detail the recent devel- 

 opments along this line in Norway and a list of references to the more important 

 literature of the subject. 



Fixation of atmospheric nitrogen, P. A. Guye (Electncien, 1905, Dec. 30, Sup., 

 p. 417; abs. in Rev. Sci. [Paris], 5. ser., 5 (1906), No. 12, pp. 376, 377).— Investigations 

 on this subject are briefly reviewed, and it is pointed out that the progress made 

 toward the development of commercially successful methods must be based upon 

 scientific investigations and theoretical considerations. 



The fixation of atmospheric nitrogen (Rev. Gen. Sci., 17 (1906), No. 6, p. 

 260).— It is stated that the method of producing expanded arcs used by Birkeland 

 and Eyde was first described by Pliicker in 1861. « 



On the utilization of atmospheric nitrogen, W. Lob ( Umschau, 10 (1906), No. 

 14, pp. 265-271, figs. 7).— An illustrated account is given of the Birkeland and Eyde 

 process as carried out at Notodden. 



The manufacture of nitric acid at Notodden, L. Grandeau (Jour. Agr. Prat., 

 n. ser., 11 (1906), No. 10, pp. 296-299, figs. 4).— The plant and methods used at this 

 place for the preparation of nitric acid from atmospheric nitrogen by the Birkeland 

 and Eyde process are described. 



The factory at Notodden, Norway, for the manufacture of nitrate, L. 

 Grandeau (Jour Agr. Prat., n. ser., 11 (1906), No, 11, pp. 328-330, figs. 2).— Further 

 descriptive details regarding the factory established at this point for the manufacture 

 of nitrate from atmospheric nitrogen by the Birkeland and Eyde process. 



The electric furnace of Birkeland and Eyde, L. Grandeau (Jour. Agr. Prat., 

 n. ser., 11 (1906), No. 9, pp. 265-268, figs. 3).— The principles of construction of this 

 furnace are explained and statistics are given as to the extent to which it is being used 

 in Norway in the preparation ol nitrogen compounds lrom the air. 



Calcium cyanamid (Mark Lane Express, 94 (1906), No. 3883, Fert. cmd Feed., 

 p. JI). —It is stated that the German Agricultural Society announces that it is now 

 prepared to furnish this material, with 19 per cent nitrogen, in limited quantities for 

 fertilizer tests at a cash price of about $53.53 per ton, in bags 1. o. b 



Nitrogen and nitrogenous lertilizers, P. G. Wic ken (Jour. Dept. Agr. West. 

 Aust., 12 (1905), No. 3, pp. 252-256) . — This article explains briefly the different 

 forms in which nitrogen occurs and discusses the fertilizing value of the nitrogenous 

 fertilizers available lor use in West Australia, including nitrate ot soda, nitrate of 

 potash, ammonium sulphate, soot, blood manure, Done dust, tankage, guanos, urine 

 and night soil, oil cake, wool waste, decomposed hair and lime lrom tanneries and 

 fellmongeries, barnyard manure, and seaweed. 



Production of nitrate, R. E. Mansfield (Mo. Consular and Trade Rpts. [U. S.], 

 1906, No. 305, p. 53).— The exports of nitrate from Chile to different countries dur- 

 ing the year 1904 are given, the total being 740,869 tons, valued at $52,847,132. 



The use of ammoniacal gas liquor as a fertilizer, C. Dusserre (Ann. Agr. 

 Suisse, 6 (1905), No. 8, pp. 333-335; Bid. Mens. Off. Renseig. Agr. [Paris], 5 (1906), 

 No. 2, pp. 183-185).— Experiments with a liquor obtained lrom the gas works of 

 Morges containing from 0.37 to 0.45 per cent of nitrogen, mostly in form of ammonia, 

 but also containing small amounts of sulphid, cyanid, sulphocyanid, etc., are reported.
