dry ground tish has cost on tlie avcnige 27.0 cents per pound. Seven 

 samples were found to have a commercial shortage. They are as 

 follows : 



E. D. Chittenden Co. Chittenden's Dry Ground Fish, No. 904. 

 Nitrogen found 8.11%, guaranteed 8.23%; phosphoric acid found 

 3.90%; guaranteed 6.00%. The manufacturer has the following to 

 say regarding this deficiency: "It would appear from the moisture 

 test that perhaps these goods were not stored in a dry place, as they 

 only tested 6.90 per cent before shipping from Baltimore, whereas 

 your analysis showed 9.97 per cent. Dr. Gascoyne's test on this 

 shipment shows 8.14 per cent of nitrogen. Our sample was drawn 

 by a sworn sampler and weighed and delivered to Dr. Gascoyne under 

 seal. We believe our sample was correctly drawn and feel that 

 Dr. Gascoyne's analysis shows that we lived up to our guarantee in 

 good faith." It might be said in this connection that another sample 

 of Chittenden's Dry Ground Fish has been analyzed, and a considera- 

 ble over-run in nitrogen was found. This second sample, however, 

 was somewhat deficient in total phosphoric acid, although no com- 

 mercial shortage was apparent. 



A. W. Higgins. Dry Ground Fish, No. 967. Nitrogen found 

 7.62%, guaranteed 8.23%; phosphoric acid found 12.69%, guaran- 

 teed 13.00%. 



Another sample of the same brand. No. 968. Nitrogen found 

 7.51%, guaranteed 8.23%; phosphoric acid found 15.15%, guaran- 

 teed 13.00%o- 



Another sample of the same brand. No. 969. Nitrogen found 

 7.06%, guaranteed 8.23%; phosphoric acid found 15.87%, guaran- 

 teed 13.00%. . 



In explanation of these deficiencies it may be said that Mr. 

 Higgins' fish was sold on the unit basis of ammonia. The consumer, 

 therefore, paid for what nitrogen was shown by actual analysis to be 

 present, — the basis of settlement to be the analysis by the Experiment 

 Station. 



Geo. E. Marsh Co. Ground Fish and Animal Tankage, No. 597. 

 Nitrogen found 5.95%, guaranteed 6.58%; phosphoric acid found 

 9.98%, guaranteed 9.15%. It is not believed that much of this 

 material was sold to the general trade. 



F. S. Royster Guano Co. . Dry Ground Fish, No. 947. Nitrogen 

 found 7.71%, guaranteed 8.23%; phosphoric acid found 5.72%, 

 guaranteed 5.00%. 



Dried Blood. Only one sample has been inspected. This was 

 listed as having cost $94.00 a ton. It tested 13.4 per cent nitrogen. 

 This would make the pound cost of nitrogen from blood 35 cents.
