Fertilizer inspection, C I). Woods and J. M. B.\rtlett {Maine iSta. Bui. 85, pp. 

 153-168). — This bulletin contains the analyses of samples collected by a representa- 

 tive of the station during 1902. A previous bulletin (E. S. R., 13, p. 1031) gave the 

 results of analyses of samples furnished by the manufacturers. "A comparison of 

 the results of the analyses of the samples collected by the station with the percent- 

 ages guaranteed by the manufacturers shows that, as a rule, the fertilizers sold in the 

 State are well up to the guarantee," although considerable variation in different 

 samples of the same brands was observed in several cases. 



Analyses of commercial fertilizers and manurial substances, C A. Goess- 

 MANN {Massachusetts Sta. Bui. 84, j>p- 30). — Analyses are reported of 253 samples of 

 fertilizers collected in the course of regular fertilizer inspection during 1902, and of 

 59 samples of fertilizing materials sent to the station for examination, including 

 wood ashes, hemp ashes, waste ashes, tan-bark ashes, brick-yard ashes, burned bone, 

 ground bone, nitrate of soda, dissolved boneblack, muriate of potash, low-grade 

 sulphate of potash, sulphate of ammonia, green celery stalk and leaf, manure, mold, 

 wool waste, sizing paste, lime, fiber waste, horn dust, tankage, complete fertilizers, 

 and soils. 



Composition and value of Avaste materials of the farm, orchard, and vine- 

 yard, G. E. Colby {California Sta. Bpt. 1S;>9-1901, pri. 2, pp. ,259--263). — Analyses are 

 reported of grape pomace, comniercial fertilizers, gypsum, citrus-fruit culls, refuse 

 prunes and olives, and other Avaste materials. Notes are given on the value of the 

 different materials. It is stated that citrus-fruit culls and grape pomace should be 

 composted Avith fresh unslaked lime or liitie refuse from beet-sugar factories in order 

 to correct acidity before applying as a fertilizer. Olive refuse and pomace on account 

 of their fat content act slowly as fertilizers. Materials containing large quantities of 

 common salt can not safely be used on certain crops, notably tobacco. 



Use of commercial fertilizers, G. M. Tucker {Missouri State Bd. Agr. Mo. But., 

 2 {1902), No. 7, pp. 4-6). — A brief discussion of general principles.

 as an adulterant of slag. 



The phosphate industry in 1902, C. C Schnatterbeck {Tradesman, 4S {1903), 

 No. 10, pp. 83-85) — In this article, quoted from the Engineering and Mining Journal, 

 consolidation of phosphate mining enterprises is stated to have been a leading feature 

 of the year. The total output during the year is reported as 1,580,997 long tons, an 

 increase of about 5 per cent over that of 1901. As regards consumption the phos- 

 phate Avas about equally divided between Germany, Belgium, and England on the 

 one hand and the southern United States on the other. The shipments of phos- 

 phates in 1902 were somewhat over 9 per cent greater than in 1901. Of the phos-
