TAKING OF SAMPLES 



To secure a fair average sample of a lot or bulk, take small 

 quantities from all of the bags or from different parts of any 

 particular bulk. Mix thoroughly and take out the sample to be 

 inspected. When the seeds are in bags or large bins, the use of 

 a grain sampler is most convenient, since this will insure getting 

 seeds from the top, middle, and bottom alike. Since the report 

 of the analysis is based upon the nature of the sample inspected, 

 it is important that the sample be carefully taken. 



SIZE AND AMOUNT OF SAMPLES 



The size and amount of the samples necessary for a test will 

 depend upon the size and weight of the seeds. About one half 

 ounce, or a tablespoonful of the smaller grass and vegetable seeds, 

 like alsike and white clover, redtop, lettuce, onions, radish, turnip, 

 etc.; about one ounce or two tablespoonfuls of the larger seeds, 

 like timothy, millet, red clover, alfalfa, rape, etc.; and about four 

 ounces, or a small cupful, of the cereal grains or vegetable seeds, 

 like oats, barley, corn, peas, beans, etc., should be sent. 



SENDING OF SAMPLES 



Samples sent to the experiment station for testing should be 

 enclosed in a strong paper envelope and securely fastened. Single 

 samples should be sent by mail at the customary merchandise rates. 

 When a number of samples are to be sent they should be put up 

 securely in a single package and forwarded by mail or express, 

 whichever way is the cheaper. Samples should not be sent in bot- 

 tles or glass jars. Each sample sent in should be marked as fol- 

 lows: 



Name and address of sender. 



Date of sending. 



Kind of seed. 



Brand name (if any), and number of package. 



Purity or germination test desired (one or both). 



Write a letter stating the number and kind of samples sent so 

 that their receipt may be promptly acknowledged.
