Mr. C. B. Saunders, Director Chief Office, Official Seed Testing Station, 



London, wished to say a few words in regard to the payment af the staff. 



At present the Treasuries of most countries do not appear to look on seed 



testing as skilled work. The result is that salaries are too low and the work 



tends to become a "blind alley" occupation. In regard to Appendix A of 



Mr. Briiijning's paper — "purity ^tests on grasses and clovers" — we have 



found that in the British Isles we were wrong in Continental eyes in our 



tests of grasses, but we thought our method agreed with the Continental 



method for testing clover. How were the Irish tests on clovers referred 



to by 'Mr. Bruijning made? On August 1, 1921 new regulations will come 



into effect. In these the percentage of germination in mangolds and beets 



will be computed on the percentage of germinated clusters. 



On page 5, appendix to Mr. Bruijning's paper is a discussion of partial 

 germination of seed, — "sprouted" or "shot" seed. Does a sprouted seed 

 •count as an impurity? 



Sprouted seed was listed as an impurity in the British seed regulations 

 passed 3 weeks ago. 



Mr. Dorph-Petersen declared that in Denmark, Sweden and Norway - 

 sprouted seed is considered dead; also in Germany. 



Dr. A. Volkart, Direktor der Samenuntersuchungs- und Versuchs- 

 anstalt in Oerlikon-Zurich, Schweiz:
