SOME WEED LAWS AND SEED-CONTROL LAWS 49 



auditor upon bills filed by the state food and dairy commissioner with 

 the executive council and approved by them. All fees collected under 

 the provisions of this act shall be paid into the state treasury. 



The above law has been enacted nearly in the above 

 form in several states as Washington and Wisconsin. 

 There are also laws in Kentucky, Maine, North Dakota, 

 Michigan, New York, and Canada. The laws of Ken- 

 tucky, Maine and Canada have been in operation longer 

 than in Iowa. The Maine law is based on a guaranty. 

 The Iowa law fixes standards of vitality and purity. It 

 is well known that vitality varies from year to year. This 

 cannot well be fixed by statute. At a recent meeting of 

 the American Association of Official Seed Analysts in 

 conference with a committee of the American Seed Trade 

 Association, and the Wholesale Seedsmen's League and 

 Wholesale Grass Seed Dealers' Association, agreement 

 was reached to recommend uniform state seed legislation 

 and require that seeds shall be sold under a guaranty 

 rather than the Iowa law, which fixes the purity and 

 vitality. Each state will naturally exclude certain weeds. 

 In Iowa the Canada thistle, dodder and quack grass 

 should be excluded.
