RAW MATERIALS CHIEFLY VALUABLE FOR NITROGEN. NITRATE OF SODA, OR SODIUM NITRATE. As offered in the Connecticut market this year, nitrate of soda has contained an average of 15.44 per cent, of nitrogen, equivalent to 93.6 per cent, of pure sodium nitrate. The following nine samples were analyzed: 9364. Sold by Apothecaries Hall Co., Waterbury. Sampled at factory. 8944. Sold by Sanderson FertiHzer & Chemical Co., New Haven. Stock of C. R.

COTTON SEED MEAL. Ninety-five samples of this material, bought for use as a ferti- lizer, have been tested. Most of the samples represent car lots. Of the 69 samples which came to the laboratory with guaranties, 26 contained the claimed amount of nitrogen and reqtdre no de- tailed report here. On the other hand, 43, or 62 per cent, of the guaranteed samples, were deficient in nitrogen. The analyses of these samples are given in the table. The deficiencies were not quite so great in amotmt as last year ranging from o.io to 0.8I per cent., with an average in the 43 samples of 0.30 per cent. Based on the average cost of nitrogen in cotton seed meal, as determined below, these deficiencies would warrant a rebate of from 53 cents to $4.29 per ton, a considerable item when the meal is piirchased in car lots. The ninety -five samples contained from 5.37 to 7.20 per cent, of nitrogen, with an average of 6.10 per cent. The average cost per ton, in the 79 samples where the price was furnished, was $44.20, about $5.50 higher than last year. Assuming 2.9 and 1.9 as the respective percentages of phosphoric acid and potash in the meal, if they are valued at 4 cents and 25 cents per pound, respectively, the nitrogen of cotton seed meal in the ninety- five samples cost on the average 26.5 cents per pound, 5.6 cents higher than last year. This is equivalent to $5.30 per unit. Most of the purchasers report that where the nitrogen in the meal was less than guaranteed they had little difficulty in securing rebates. In our judgment the rebates did not fully compensate for the deficiency where not more that $4.00 per unit was allowed. Cer- tainly, at present prices of meal, $5.30 per unit is none too high a rebate. COTTON SEED MEAL. 377 Cotton Seed Meals Below Guaranty. Manufacturer or Jobber, Car No. or Marks.

This is a residue from the manufacture of castor oil and is used chiefly as a tobacco fertilizer. Experience indicates that it is a little slower in its action than cotton seed meal and that it gives a somewhat heavier quality to the tobacco leaf. Stock will eat it greedily if they have the chance, but it is extremely poisonous. The following eight samples were analyzed : 8940. Sold by American Agricultural Chemical Co., New York City.

Sample 8871 was 1.55 per cent, deficient in nitrogen. The average nitrogen content of the samples was 4.60 per cent, and the average cost per ton, $31.28. Assuming a value of 4 cents per pound for phosphoric acid and 25 cents per pound for potash, the average cost of nitrogen per pound in castor pomace this year was 27.3 cents, or $5.46 per unit. n. RAW MATERIALS CHIEFLY VALUABLE FOR PHOSPHORIC ACID. BASIC LIME PHOSPHATE. Shipments of basic phosphate from abroad have been almost cut off on account of the war. As a substitute for basic phosphate a product called "basic lime phosphate" has been put on the mar- ket, of which we have analyzed four samples of two brands. "Available phosphoric acid" was determined by the so-called Wagner method. 9367. Basic Lime Phosphate. Sold by American Agrictdtural Chemical Co., New York City. Stock of C. R.

PRECIPITATED BONE PHOSPHATE. This is a manufacturing by-product and consists of fine precipi- tated phosphate of lime, neutral in reaction, and contains no nitrogen. It is very readily soluble in ammonium citrate solution and is quickly available to crops. It is at present chiefly used as a tobacco fertilizer. Six samples were analyzed, all of which were sold by Olds and Whipple, Hartford. 9371 was sampled by the Station at the factory, and 9373 by the Station from the stock of F. T. Phelps, Suffield; 8711, 8712 and 8742 were sampled and sent by the seller; 8872 was sampled and sent by Karl C. Kulle, Suffield. The respective car.ntimbers for the last .four samples were 88300, 73792, 4822 and 73365- The guaranty for the material was 28 per cent, "available" and 32 per cent, total phosphoric acid.

DISSOLVED ROCK PHOSPHATE OR ACID PHOSPHATE. This material is made by treating mineral phosphates or phos- phate rock with oil of vitriol (sulphuric acid) , which converts the larger part of the phosphoric acid into forms soluble in water, and at the same time changes into sulphate of lime a large part of the lime which was previously combined with phosphoric acid. The guaranty usually gives the percentage of "available" phos- phoric acid. This is only a trade name for the sum of the water- soluble and citrate-soluble phosphoric acid. Its amotint gives no certain indication of the actual availabliity of this phosphoric acid to crops. In acid phosphate, however, well made from domestic rock, it is fair to assiune that the larger part of the "avail- able" is also agriculturally available.

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 15.34 per cent, phosphoric acid, chiefly in in- soluble 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 dis- pose of their surplus stock. " MURIATE OF POTASH. 8691, 8692. Stock of Samuel Wilson, Waterbury. They con- tained 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 poimd for actual potash. It contained 24.78 per cent, of potash. 384 CONNECTICUT EXPERIMENT STATION BULLETIN 204. IV. RAW MATERIALS CHIEFLY VALUABLE NITROGEN AND PHOSPHORIC ACID. FOR 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. x\nalyses of Manufacturer Dealer or Purchaser 8921 9045 9323 9365 9325 9374 9357 8924 9354 8925 9100^ 8873 Sampled by Station: Amer.

(Analyses on pages j86 and 387.) This material, made fromi 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 1 1. 1 9 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 : Grade. Nitrogen. Phosphoric Acid. Cost per Ton. 6-30 9-20 4.78 7.83 17-39 7.96 $35-33 51.00 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. Fish Manures.
