herein provided, together with the names and addresses of the persons from whom the 

 samples of seed were obtained. He may publish such other information as he may deem 

 advisable concerning the value, character and use of certain seeds. 



2. Takes Effect. This act shall take effect upon its passage. 

 Approved March 10, 1943. 



RULES AND REGULATIONS 



Sampling. 



(a) In order to secure a representative sample, equal portions shall be taken from 

 evenly distributed parts of the quantity of seed to be sampled. Access shall be had to all 

 parts of that quantity. 



(b) For free-flowing seed in bags or bulk, a probe or trier shall be used. For small 

 free-flowing seed in bags, a probe or trier long enough to sample all portions of the bag 

 shall be used. 



(c) Non-free-fiowing seed, such as certain grass seed, uncleaned seed, or screenings, 

 difficult to sample with a probe or trier, shall be sampled by thrusting the hand into the 

 bulk and withdrawing representative portions. 



(d) The portions shall be combined into a composite sample or samples. 



(e) As the seed is sampled, each portion shall be examined, and, whenever there 

 appears to be a lack of uniformity, additional samples shall be taken to show such lack of 

 uniformity as may exist. 



Bulk seeds shall be sampled by inserting a long probe or thrusting the hand 

 into the bulk as circumstances require in several uniformly distributed parts of the quan- 

 tity being sampled. 



Bags. (1) In quantities of five bags or less, each bag shall be sampled. 



(2) In quantities of more than five bags, at least every fifth bag but not less than five 

 bags shall be sampled. Samples shall be drawn from unopened bags except under circum- 

 stances where the identity of the seed has been preserved.. 



In sampling packet seeds, entire unopened packets shall be taken. 



Size of sample. The following are minimum weights of samples of seed to be 

 submitted for analysis, test, or examination: 



(1) Two ounces of grass seed not otherwise mentioned, white or alsike clover, or seeds 

 not larger than these. 



(2) Five ounces of red or crimson clover, alfalfa, ryegrass, brome-grasses, millet, flax, 

 rape, or seeds of similar size. 



(3) Two pounds of cereals, vetches, or seeds of similar or larger size. 



(4) Two quarts of screenings. 



Analysis. 



The New Hampshire seed laboratory will be guided in making purity and ger- 

 mination tests by the rules and regulations prescribed under the Federal Seed Act. 



Tolerance. 



Owing to the natural variation between tests, the following tolerances shall be 

 allowed between the percentages found by analysis, test or examination and the percentages 

 stated on the tag accompanying the seed: 



For purity: Allowing "a" to represent the component being considered and 

 "b" the difference between that percentage and 100, according to the following formula: 



l o a X° \ 



Pure seed tolerance = 0.6-5- \ 0.2 X Jqq~ ) 



a sample of timothy guaranteed 99.20 would have an allowable variation of .75 or could 

 test as high as 99.95 or as low as 98.45 and be "satisfactory."
