In testing seeds for purity, a careful selection of samples is of the 

 most importance in obtaining results which will correctly represent 

 the quality of the stock of the seeds or of the shipment being ex- 

 amined. Your attention is, therefore, called to this matter in order 

 that if any of the members of the Board desire to have seeds tested 

 or to direct others in getting this information, special care can be 

 taken in securing special samples. If the seed is in sacks, bags or 

 other large containers, samples should be taken from several differ- 

 ent places, thoroughly mixed and the following directions carefully 

 followed: r| ^:^:^ 



AMOUNT OF SAMPLE: 2 to 4 ounces, carefully secured and rep- 

 resentative of whole lot. 



ENVELOPES: Should be used and carefully sealed. 



ADDRESS: Bureau of Chemistry, Pennsylvania Department of 

 Agriculture, Box R, Harrisburg, Pa. The name of seed and address 

 of sender should be also included. 



CHARGE FOR PURITY TEST: 25 cents is the fee charged and 

 it should be submitted with sample in the form of a certified check, 

 money order or cash. If cash is sent for one or two samples, it may 

 be inserted in the sample of seed with safety, if the envelope is care- 

 fully sealed. 



After the seed tests have been completed, reports are sent to the 

 senders stating the name or kind of seed received, the percentage of 

 pure seeds, foreign seeds and inert matter, the presence of freedom 

 of dodder or Canada thistle, together with a receipt for the fee 

 charged. The following explanation of what is meant by pure seed, 

 foreign seed and inert matter will be of assistance in judging from 

 the reports received the character of the samples examined: 



PURE SEED: Consists of the seeds under examination only. If 

 for example, red clover is being tested for purity, the percentage of 

 "pure seed" represents the amount of red clover seed present by 

 weight in a given quantity. 



FOREIGN SEED: Includes the amount of all other seeds present 

 which differ from the kind of seed under examination. 



INERT MATTER: Includes all materials other than pure and 

 foreign seeds, such as less than half parts of seeds, broken stems, 

 dirt or any other foreign material.
