Subsequently committees were appointed by the Association of 

 American Agricultural Colleges and Experiment Stations and the 

 Association of Official Agricultural Chemists, which conferred upon 

 the subject of fertilizer laws and agreed upon changes which should 

 be made in the interest of uniformity in the several States. The 

 report, signed by H. J. Wheeler, H. P. Armsby, E. H. Jenkins, 

 M. A. Scovell, and C. D. Woods, recommended that State laws 

 should be made uniform on the following points : 



1. All substances containing nitrogen, potash, or phosphoric acid, sold, offered, 



or exposed for sale for manurial purposes, excepting the dung of domestic 

 animals when sold as such, should be subjected to inspection. 



2. Each package of manurial substance as above denned, sold, offered, or 



exposed for sale, should bear a printed, legible guaranty. 



3. The number of net pounds in each package should be stated. 



4. Each package should 'bear the brand, name, or trade-mark, and the name 



and address of the manufacturer. 



5. The quantities of manurial ingredients should be expressed in percentages. 



6. The guaranteed statements on the packages or forwarded to the inspectors 



need not be in the form of an affidavit. 



7. Sealed samples of fertilizers offered for sale need not be sent by the manu- 



facturers to the. inspectors. 



8. In lots of five tons or less, samples should be drawn from at least ten pack- 



ages, or if less than ten packages are present, all should be sampled ; in 

 lots of over five tons, not less than twenty packages should be sampled. 



9. Duplicate samples should be drawn and sealed in the presence of the party 



or parties in interest, or their representatives, one of the samples to be 

 taken by the collector and the other left with the party whose goods were 

 inspected, subject to the call of the manufacturer. 



10. Total nitrogen should be guaranteed in all cases, and nitrogen in the form 



of nitrates or ammonium salts should be guaranteed separately, if the 

 manufacturer desires credit therefor. 



11. Total phosphoric acid should be guaranteed in all cases, and soluble, reverted, 



and insoluble, separately, if the manufacturer desires credit therefor. 



12. Potassium should be guaranteed as potash (potassium oxid) soluble in 



water. 



13. When chlorin is present in fertilizers, manufacturers shall guarantee the 



maximum percentage thereof. 



14. Only statements of the minimum amount of the substances present, except 



in the case of chlorin, should be made. For example, instead of guaran- 

 teeing from 2 to 4 per cent of potash, guarantees should read thus : 2 per 

 cent of potash. 



15. It should be specified that the methods of the Association of Official Agri- 



cultural Chemists should be used for official work. 



16. An imprisonment clause for violation of fertilizer laws should be omitted. 



17. Manufacturers should not be obliged to secure bondsmen. 



18. Commercial valuations should not be affixed to the published analyses of 



manurial substances. 



19. A definition of the term "brand" should be inserted wherever a brand tax 



is assessed.
