germinating dishes. Occasional use is made of sawdust and filter 

 paper, and seeds are frequently planted in soil. 



Directions for Sending Seeds for Separation, Germinating Tests, Etc. 

 In sending seeds to be tested for germination a sufficient quantity 

 should be forwarded to enable a fair average of the sample to be 

 obtained. 200 seeds at least should be sent, and as it requires seve- 

 ral days to make a test, samples should be sent in sometime previous to 

 the proposed date of planting. Samples sent in for separation shou d 

 include return postage or express, together with statement as to wheth- 

 er discarded seed should be returned. All packages and letters 

 pertaining to seed testing and separation should be addressed to 

 G. E. Stone, Mass. Agr. Exp. Sta., Amherst, Mass. 



Conclusions. 



The principal object of this bulletin is to set forth the advantages 

 to be gained from the use of separated seed and to interest farmers 

 and gardeners in seed separation, and we recommend it particularly 

 to those following lines of intensive agriculture. Onion and tobacco 

 growers make use of separated seed, and we strongly advocate mar- 

 ket gardeners doing this also. Lettuce seed can be easily separated 

 with a sieve, in this way saving labor and space, besides securing 

 more uniform and vigorous seedlings. 



We regard seed separation as an important aid in securing larger, 

 more vigorous and more uniformly developed crops and recommend 

 its use wherever practicable.
