of expeiinients in contii'uatioii of tliosc carried out in 1S<)4 {E. S. R., 

 7, p. 24) for the purpose of determininj:^ the relative agricultural value 

 oi' siiperi)1iospliate, Ciply and Li('j;e phosphates, and Thomas slag-. Data 

 are tabulated in detail for experiments in 1895 on oats following beets, 

 peas following maize, clover following oats, wheat following clover, and 

 on dry and wet meadows. 



Summarizing the results for the 2 years, it appears that as regards 

 yield the superphosphate gave the best results on oats following clover, 

 on clover following wheat, and on dry meadows; and the slag gave 

 best results in the oats beet, and peas-corn lotatiou, and on wet 

 meadows. With respect to profit secured, the slag gave the best results 

 in every case except on the dry meadows, on which the superphosphate 

 gave the most profitable return. The latter also gave a jjrofit in all 

 other cases except on the wet meadows. As regards the amount of 

 phosphoric acid which the plants utilized of the different applications, 

 the slag appears in most cases to stand ahead of the other j^hosphates. 

 In general it is recommended that for soils of the character used in 

 these experiments the superphosphate or slag should be used, since 

 they give an increase of yield and a profit double that of the mineral 

 phosj)hates. 



Fertilizers {Connecticul kStafc 8ta. Bpt. 1895, pp. 1-7-1). — A statement 

 of the amount of fertilizers used in Connecticut; an abstract of the 

 State fertilizer law; a list of manufacturers complying with the law; 

 notes on the sampling and collection of fertilizers; explanations con- 

 cerning the analysis and valuation of fertilizers; methods and results 

 of home-mixing of fertilizers; a review of the fertilizer market for the 

 year ending JS^ovember 1, 1895; and tabulated analyses and valuations 

 of 191 samples of fertilizing materials, including nitrate of soda, dried 

 blood, leather, cotton-seed meal, castor pomace, dry ground fish, beef 

 scrap, tankage, bone, mineral phosphates, dissolved boneblack, dissolved 

 rock phosphates, sulphate of potash, sulphate of potash and magnesia, 

 muriate of potash, cotton-hull ashes, wood ashes, anthracite coal ashes, 

 saltpeter waste, swamp muck, marine mud, and factory-mixed and 

 h( me-mixed fertilizers. 



The principal results of the inspection maybe summarized as follows: 



"Of the 76 aualyses of nitro^i^enous superphosphates [examined] 21 are below the 

 maker's minimum guaranty in respect of 1 ingredient, 5 in respect of 2, and 1 in 

 respect of all 3 ingredients. Thus more than one-third of the whole uumljer do not 

 fulfill in all respects the maker's claim for them. . . . 



"The average cost of the superphosphates is $32.32. The average valuation is 

 $23.37, and the percentage difference 38.2. . . . 



"Of the 78 ])rands of special manures 19 are below the manufacturers' guaranty 

 in respect of 1 ingredient and 10 in respect of 2 ingredients, so that in all, consid- 

 erably more than one-third of the whole numl)er do not in all respects fulfill the 

 manufacturers' claims. Kejecting from calculation 3 analyses, the average cost 

 of 75 special manures was $37.33 i»er ton. The average valuation was $27. 5M. The 

 difterence, $9.30, is equivalent to a 'percentage difference' of 33.6. Last year the
