36 EXPERIMENT STATION RECORD. 



estimate for 1895 was too high, owing to a considerable number of tags being carried 

 over which were really used in 1896, although they appear in the 1895 sales. It is 

 probable that an estimate of 42,000 tons in 1895 and 45,000 tons in 1896 would more 

 nearly express the real facts. . . . 



"The amount of plant food in the fertilizers sold in 1896 includes 5,643 tons of 

 actual phosphoric acid, of which 3,171 tons were in the form of 'available' in acidu- 

 lated goods, 1,143 in the form of 'insoluble' in acidulated goods, and 2,320 tons were 

 in bone .and non-acidulated packing-house products. . . . 



"The amount of nitrogen contained in the fertilizers sold in 1896 was 884 tons, 

 equivalent to 1,073 tons of ammonia. Nearly all of this was derived from packing- 

 house products, although a few of the samples contained nitrate of soda and tobacco 

 stems and garbage products. 



"The amount of actual potash contained iu the fertilizers sold was 562 tons." 



Functions, composition, and valuation of manure (Jour. Bureau Agr. Adelaide, 

 Australia, 9 (1S97), No. 8, p. 271). 



Fertility imparted by manuring and derived from atmospheric sources, P. C. 

 Solomon (Agl. Gaz. [London], 45 (1897), No. 1216, p. 371).

Investigations on the best methods of handling barnyard manure (Mitt. dent, 

 landw. Gesell, 12 (1897), No. 1.', p. 57; aba. in Chem. Ztg.,21 (1897 I, No. 33, Repert.,p. 94). 



Barnyard manure and commercial fertilizers, B. Fallot (Prog. Ayr. et Yit., 27

Bone meal adulterated -with sand, A. Atterberg (Tidskr. Landtman, 17 (1896),

Thomas slag, L. Gkandeau (Ann. Sci. Agron., 1S97, I, No. 1, pp. 1-157, figs. 2). — The 

 results of investigations by the author and others, especially Wagner, Maercker, and 

 Hoyerman, and of practical experience in the use id* Thomas slag, .are summarized, 

 and the production, composition, and use of slag under different conditions of soil, 

 crop, etc., are discussed. The conclusions are reached that the citrate! solubility 

 determined according to Wagner is by no means a criterion of the fertilizing value of 

 phosphates, and that slag should be bought on guaranty of total phosphoric acid 

 and of line meal. The latter should amount to 75 to 80 per cent.
