One of the above samples was guaranteed 18 per cent. "available"; ten were guaranteed 16 per cent., and five 14 per cent. The average cost of "available" phosphoric acid in the above samples was 6.2 cents per pound, about 0.75 cents less than last year. PHOSPHO PLASTER. 9368. Sold by American Agricultural Chemical Co., New York City. Stock of A. L. Burdick, Westbrook. Guaranteed 2 per cent. "available" phosphoric acid. It contained 9408. Sold by Witherbee, Sherman & Co., Port Henry, N. Y. Stock of Station Farm, Mt. Carmel. Guaranteed 14 per cent. phosphoric acid, 7 per cent. barium sulphid. It contained 15.34 per cent. phosphoric acid, chiefly in insoluble forms. III. RAW MATERIALS OF HIGH GRADE CONTAINING POTASH. Owing to the war very little, if any, potash has been shipped to this country during the past three years. The three samples of muriate of potash analyzed represented stock in the hands of farmers who were tempted by the abnormally high prices to dispose of their surplus stock. MURIATE OF POTASH. 8691, 8692. Stock of Samuel Wilson, Waterbury. They contained 53.92 and 52.44 per cent. of potash, respectively. 8801. Stock of W. T. Peters, Cheshire. It contained 58.24 per cent. of potash. COTTON HULL ASHES. 9279. Sold by Olds and Whipple, Hartford. Car No. 22120; stock of Windsor Tobacco Growers Corporation, Windsor. Cost $6.00 per unit of water-soluble potash, equivalent to 30 cents per pound for actual potash. It contained 24.78 per cent. of potash. Station No. IV. RAW MATERIALS CHIEFLY VALUABLE FOR NITROGEN AND PHOSPHORIC ACID. FISH MANURES. The twelve samples analyzed show considerable uniformity in the content of nitrogen, which ranges from 7.28 to 9.75 per cent., with an average of 8.34 per cent. The phosphoric acid, however, shows a wide range, from 2.75 to 10.41 per cent., with an average of 6.77 per cent. Six of the samples failed to meet their guaranties, two being deficient in nitrogen, one in phosphoric acid, and three in both of these elements. 9365 and 9100 contained only about half of the phosphoric acid guaranteed. The average cost was $53.44 per ton, about $2 higher than last year. If the phosphoric acid were valued at 4 cents per pound, the nitrogen cost on the average 28.8 cents per pound; if at 6 cents per pound, the nitrogen cost 27.2 cents.

(Analyses on pages 386 and 387.) This material, made from the waste of slaughter houses and meat markets, naturally shows considerable differences in composition, depending upon the relative amounts of meat and bone present. The thirteen samples analyzed fall into two quite well-defined groups, the one containing from 4.26 to 5.67 per cent. of nitrogen and from 14.06 to 21.42 per cent. of phosphoric acid, the other containing from 7.16 to 8.34 per cent. of nitrogen and from 5.62 to 11.19 per cent. of phosphoric acid. The samples of the first group, approximately 6-30 grade, cost from $28 to $42 per ton; the higher grade tankages, 9-20, cost from $48 to $55 per ton. The average composition and cost of the two grades were as follows: Only four of these samples could be called fine, having 50 per cent. or more by weight in particles smaller than 1-50 inch. Two samples failed to meet their nitrogen guaranty, one that for phosphoric acid, and one was deficient in both nitrogen and phosphoric acid. Nitrogen FISH MANURES. Phosphoric Acid.

"Bone," like tankage, has a wide range of composition, some samples being from raw bone with or without much adhering meat and cartilage, others representing bone which has been cooked, the grease and nitrogenous matter being partially removed. The average per cent. of nitrogen in these samples is 3.40 and of phosphoric acid 23.35. The average cost per ton, barring the exceptional prices of 9393 and 9387, was $40.60. Two samples failed to meet their nitrogen and two their phosphoric acid guaranties. V. MIXED FERTILIZERS. NITROGENOUS SUPERPHOSPHATES. REGARDING GUARANTIES. The following tables, pages 394 to 415, present 375 analyses. Of those sampled by the Station Agent 143 are guaranteed to contain potash. 172 contain no potash. Three brands were guaranteed to contain four per cent. of potash, though only one had nearly that amount. Seven brands guaranteed 3 per cent., nineteen 2, and the rest 1 per cent. or less. Of the brands containing potash about 23 per cent. failed to meet their guaranty in one ingredient, while of the 172 without potash 16.8 per cent. failed in the same way. In a large number of cases, however, a shortage of one ingredient was made good by an overrun of another, so that the buyer received full value for his money, but in the following brands this was not the case. Reckoning nitrogen at 27 cents, available phosphoric acid at 6 and potash at 30 cents per pound, respectively, the deficiency in money value per ton was: 9039 Rogers & Hubbard Co.'s Bone Base Soluble Potato. 1.68 1-50 inch.
