C for Variety Tests. Unofficial Samples The term "unofficial samples" is applied to .seeds submitted by dealers and •growers for examination and for which service a fee is charged. This work is believed to be of material value to both dealer and grower, espe- cially where any doubt exists as to the quality of the seed. Manner of storage and the age of seed are such important factors in seed vitahty that a laboratory test is advisable where there is any question as to age or manner of storage. A purity test on grass seed or grass seed mixtiyes will also determine to what extent such seed been freed from foreign seed and inert material. The average time required for a germination test varies from ten to twenty- eight days; some of the grass seeds taking the longer time. Therefore, seeds should be submitted a sufficient length of time in advance to make sure of obtain- ing a report before planting time. Samples should be sent to the Seed Testing Laboratory, Massachusetts Agri- cultural Experiment Station, Amherst, Massachusetts. Rules and Regulations Governing the Testing of Seeds for Purity and Germination (1) The kind of seeds that will be tested are those specified in the Massachu- setts seed law, and in addition, flower seeds may be tested for germination.
