Report on commercial fertilizers, 1905, E. II. Jenkins and A. L. Winton 

 (Connecticut stair shi. Upt. 1905, pt. I. i>i>. 9-106). — Tbis includes a statement 

 of the duties of manufacturers and dealers and of the experiment station in 

 connection with the inspection under the State fertilizer law. a list of firms 

 licensed to deal in fertilizers in the State during 1905, notes on the methods 

 followed in sampling and collecting fertilizers, a classification of the fertilizers 

 analyzed, descriptions (with analyses) of fertilizing material furnishing nitro- 

 gen, pbospboric acid, and potash in fertilizers, and explanations regarding the 

 valuation of fertilizers. 



Tabulated analyses and valuations are given of GOO samples of fertilizing 

 materials, including nitrate of soda, dried blood, cotton-seed meal, castor pomace, 

 flaxseed meal, dissolved rock phosphate, charred bone, carbonate of potash, 

 high-grade sulphate of potash, double sulphate of potash and magnesia, muriate 

 of potash, kainit, saltpeter waste, bone manures, slaughterhouse tankage, dry 

 ground fish, superphosphates with potash salts, nitrogenous superphosphates, 

 special manures, home-mixed fertilizers, vegetable potash, cotton-hull ashes, 

 wood ashes, limekiln ashes, garbage ashes, lime, South American guano, sweep- 

 ings from a fertilizer factory, dust from wheat, pulverized sheep manure, rotted 

 cotton-seed compost, dust from tobacco, and woolen carpet waste. 



The cash retail cost per pound in Connecticut of nitrogen in raw materials 

 during 1905 as shown in this report was, in nitrate of soda, highest 17.5, lowest 

 16.4, average 16.9 cts. ; dried blood, average 21.9 cts. ; cotton-seed meal, highest 

 20.6, lowest 14.2, average 16.4 cts.: castor pomace, highest 24.5, lowest 20.4. 

 average 22.4 cts. ; and flaxseed meal, average 21.9 cts. 



The price of available phosphoric acid in form of dissolved rock phosphate 

 was. highest 4.8, lowest 4.3, average 4.5 cts. per pound. 



The price per pound of potash in raw materials was, in high-grade carbonate, 

 highest 7.3, lowest 0.7. average 7.1 cts. : carbonate as " vegetable potash," 

 highest 8.1, lowest 7.9, average 8 cts. ; high-grade sulphate, highest 5,3, lowest 

 4.8, average 5 cts.; double sulphate, highest 5.9, lowest 4.«). average 5.3 cts. ; 

 muriate of potash, highest 4.5, lowest 4, average 4.25 cts. ; saltpeter waste, 

 average, 0.7 ct. : and kainit. average 4.7 cts. 



The price of lime per 100 lbs. was. in wood ashes, average 34 cts. ; limekiln 

 ashes, highest 15. lowest 4.3; and ground slaked lime, average 85 cts. 



Commercial fertilizers, P. Evans (Missouri Fruit Sta. Bui. 13. pp. 23, fig. 

 1). — In this bulletin an attempt is made to give "such information pertaining 

 to the use of fertilizers as may he of use to the general inquirer. The informa- 

 tion offered, however, does not come from the results of actual experiments 

 conducted at this station, but rather is a general summary of the subject." 



Analyses and valuations of commercial fertilizers, J. P. Street, W. P. 

 Allen, and V. J. Carberky (New Jersey St<ts. Bui. 188, pp. £6).— This is a 

 second report on fertilizer inspection during 1905. the first being given in Bul- 

 letin 187 of the station ( E. S. R.. 17, p. 450). 



The trade values of fertilizing ingredients for 1905 are discussed and the com- 

 position of standard materials supplying them, station valuations are compared 

 with actual selling prices, suggestions made regarding the purchase of fer- 

 tilizers, and results reported of examinations of 104 samples of standard un- 

 mixed materials. 11 home mixtures. 20 special mixtures. 380 complete fertilizers. 

 and 29 miscellaneous materials. " With a few exceptions the analyses indicate 

 that the materials were cf good quality, although the usual wide variations 

 are shown in the case of dried fish and tankage,"
