Nitrogen in Nitrate of Soda has cost at loholesale through the 

 year less than in any other form. It was quoted in November, 

 1«81, at $20.40 per 100 lbs., which is the highest figure for the 

 year. From then it steadily declined till last September, when it 

 cost ^16.80, and on the first of November of this year stood at 

 $17.55 to $18.40. The average price asked by the large retail 

 houses in New York has been about $22 to |23, according to the 

 bulletin of the New Jersey Station. No analyses have been 

 made in this Station of articles of this class which were of average 

 quality or price. 



Soluble Phosphoric Acid in the three samples examined here 

 has cost at retail in this State $10.84 on the avei'age. In New 

 York it has retailed at $10.72 when made from South Carolina 

 rock, and a little less when made from bone black. 



Insohible Phosphoric Acid has shown no very marked changes 

 during the year. Chai-leston rock unground, "free on board," 

 (f. o. b.) at Charleston was quoted at $8.80 per ton in January, 

 and has fallen since, the quotation on Nov. 1st, 1882, being $6 to 

 $6.50. Ground and rough bone have also been quite steady in 

 price, the latter sort ruling highest in November and December, 

 1881. 



Potash as high grade (80 per cent.) muriate has been very 

 steady, prices ranging from $3.24 to $4,06 per 100 lbs., since 

 May, 1881, and averaging $3.60; small lots purchased in New 

 York have cost on the average $4. In Connecticut it has retailed 

 this year for about $4.50. 



Potash as high grade sulphate seems not to be in the retail 

 market in Connecticut to any amount. 



Potash in the double sulphate of potash and magnesia has cost, 

 making liberal valuation for sulphate of magnesia, $6.77 and $6.45 

 per 100 lbs. at retail in the Connecticut market. Only one sample 

 of kainite has been analyzed here. Potash in that article has 

 retailed in New Jersey^for $5.06 per 100 lbs. on the average. 



From the Review of the Fertilizer Market it appears that the 

 prices of certain fertilizers have varied very considerably during 

 the vear. To take a single instance : the nitrogen of dried blood 

 cost at wholesale not far from 23|^ cents a pound in November, 

 1881, but could be got for a little less than 19 cents a pound 7 

 months later, in June, 1882. Assuming that the blood had 10 

 per cent, of nitrogen, this would be a diflference of over $7 per 

 ton in the cost, an item well worth saving if it can be saved.
