It is quite probable that the same conditions that affect blue 

 grass seed affect the seed of red top also, and that if tests were 

 made in soil the general average of vitality might be found to 

 be considerably higher. Better methods of gathering and dry- 

 ing would doubtless work toward the same end. 



Orchard grass. Dactylis glomerata. — The most extensive tests- 

 of this seed of which I have any knowledge were made at the 

 Connecticut experiment station in 1892. Seventeen samples 

 from different eastern markets were obtained and tested. One 

 was found to contain no seed of orchard grass at all. The 

 results from the remaining sixteen are given in the following 

 table :

Timothy. Phleum pratense. — Timothy has been tested for 

 vitality a great many times and approaches more closely to the 

 standard than any other grass. The comparative results are 

 given below:
