1 Over one-half of the nitrogen contained in this product is soluble m water and the part that is insoluble 

 in water shows a very satisfactory activity by means of neutral permanganate method. The actual avail- 

 ability of that part of the nitrogen which is insoluble in water was shown by a vegetation test made in 1926 

 to be about 45 per cent, as compared with 80 per cent for dried blood. 



2 This material is a by-product from wi;ol carding. It is composed largely of sheep manure which is re- 

 moved from the fleece in the carding process. It also contains wool fiber as well as seeds of a great variety 

 of plants. 



3 This product shows the presence of 1.02 per cent of water soluble phosphoric acid, 3.50 per cent of citrate 

 soluble or so-called reverted and 5.80 per cent of insoluble phosphoric acid. This indicates the addition 

 of both acid phosphate and phosphate rock, or possibly ground bone. Allowing for a normal amount of 



, phosphoric acid from the sheep manure, the excess of phosphoric acid shown by this analysis, if derived 

 from an average grade of acid phosphate, should show at least 9 per cent of available phosphoric acid, and 

 would mean that about equal parts of 16 per cent acid phosphate and sheep manure were used in making 

 the product. Correspondence with the producer establishes the fact that acid phosphate was used for the 

 purpose of conserving the ammonia which would otherwise be lost during the fermentation of the manure. 

 The product should be called sheep manure and acid phosphate. About 85 tons of the material were sold 

 in Massachusetts. 



* Collected at Great Harrington. Commercial valuation $9.08. Commercial shortage $1.22 per ton. 

 s This product has not been registered for sale in Massachusetts. Two dozen packages, each weighing 

 about two pounds and costing twenty-five cents, were found with the Waltham Nurseries. It was under- 

 stood that the product was not bougiit for resale. The Plantspur Products Co. deny having sold the prod- 

 uct in Massachusetts and suggest that it was procured through some distributing agent located in New 

 York. The material proved to be a mi.xture of garbage tankage, cocoa shells, ammonium sulfate, acid 

 phosphate, muriate of potash, and possibly some sheep manure. Registration of the product was refused 

 in Massachusetts under the name "Sheep Manure Fertilizer." If registered under a name that was not 

 misleading there would be no objection to the sale of the product.
