For germination : The following tolerances are applicable : 



Healthy sprouts found by test in each 100 seeds Tolerance 



96 or over 5 



90 or over but less than 96 b 



80 or over but less than 90 7 



70 or over but less tlian 80 8 



OO or over but less than 70 9 



Less than 60 10 



Therefore, a sample of seed guaranteed 85% for germination may be as high as 



92% or as low as 78% and be "satisfactory." 



For weed seeds: The law requires in the labeling of agricultural seed (1) 

 that the percentage of all weed seeds present shall be shown on the tag, (2) that no 

 I)rimary noxious weed seeds shall be ])resent in the sample, and (3) that ,secondarj\' 

 noxious weed seeds shall bp given by name and approximate number, per ounce in 

 groups (A) and (B) and per pound in groups (C) and (D), when present singly or 

 collectively in excess of — 



(A) One seed or bulblet in each 5 grams of Agrostis species, Poa species, 

 Rhodes grass, Bermuda grass, timothy, orchard grass, fescues (except meadow fescue), 

 alsike and white clover,, reed canary grass, Dallis grass and other agricultural seeds of 

 similar size and weight, or mixtures within this group : 



(B) One seed or bulblet in each 10 grams of negrass, meadow fescue, foxtail 

 millet, alfalfa, red clover, svveetclovers, lespedezas, smooth brome, crimson clover, 

 Brassica species, fiax, Agropyron species, and other agricultural seeds of similar size 

 and weight, or mixtures within this group or of this group with (A) ; 



(C) One seed or bulblet in each 25 grams of proso, Sudan grass and other 

 agricultural seeds of similar size and weight, or mixtures not specified in (A), (B), or 

 (D); 



(D) One seed or bulblet in each 100 grams of wheat, oats, rye, barley, buck- 

 wheat, sorghum (except Sudan grass), vetches, and other agricultural seeds of a size 

 and weight similar to or greater than those within this group, or any mixtures within 

 this group. 



Certain tolerances are allowed, however, to provide for variations and imavoid- 

 able errors, but only within very narrow limits and for which there is always a standard 

 formula for computation. Examples: (1) Timothy guaranteed only 2 per cent weed 

 seeds will not be condemned if it has 2.59 per cent. (2) No primary noxious weed 

 seeds are allowed, but the presence of two such seeds in 50 grams of timothy would not 

 be considered a violation. (3) Similarly, some slight variation from the minimum re- 

 ijuirement for labeling secondary noxious weed seeds will be ])assed as satisfactory. 



Free Testing. 



The Seed Testing Laboratory will allow six free tests, in a given year, to any 

 resident company or person of New Hampshire, but such seeds must be received in 

 the laboratory during the months of November, December, January and February. This 

 number of samples, not including mixtures, may be analyzed either for purity or for 

 germination, or three samples for both purity and germination, free of charge. A given 

 seed company will be entitled to six jirivate tests without charge, but not six from each 

 branch store. For numbers in excess of six, a charge will be made for labor and con- 

 sumable supplies only, the amount depending on the type of sample according to the 

 following schedule : 



Germination tests of all crop seeds, including timothy, clovers and alfalfa, 

 25 cents each ; 



Germination tests of all grasses except timothy, 50 cents each ; 



Germination tests of mixtures, 25 cents for each kind of seed present ; 



Purity analyses of cereals like corn and oats, 50 cents each ; and of timothy, 

 75 cents each ; 



Purity analyses of all other kinds of crop seeds, except grasses, 75 cents each ; 



Purity analyses of the smaller grass seeds and of all mixtures of not more tlian 

 two kinds of agricultural seeds, 1.00 each; 



All purity analyses of special mixtures, including those for lawn and pasture 

 seeding, a charge sufficient to cover the actual cost of working tlie sami>lc submitted 

 for test, minimum charge of $1.25.
