Mr. S wayne, (a) that there was reason to think that the common cultivated 

 Ray-grass had by frequent sowing degenerated from its natural qualities, 

 that it was inferior in many respects to the Ray-grass growing naturally 

 in our best meadows and pastures. Mr, Pacey, an enlightened agricul- 

 turist in the upper part of this county, has lately raised a" variety of tLaf* 

 grass from seed selected from old pastures, and has now multiplied it to 

 that extent as to sell annually a considerable quantity at the price of iOs. 

 6d. per bushel. It has been proved by the most competent judges, to 

 be infinitely superior to the cultivated Ray -grass, and he has a demand 

 for all he raises. What can have been the cause of the degeneracy of 



the cultivated sort? Has the temulentum had any share in this mischief? 

 Mr. Swayni. 



* The seeds, mixed with bread-corn, produce but little effect, unless 

 the bread be eaten hot ; but, if malted with barley, the ale soon occasions 

 drunkenness. Linn. Made into bread, with a small proportion of wheat, 

 and eaten repeatedly, produced vomiting, purging, violent colics, and 

 death. Vol. 67. M. Review, p. 559. —Sheep are not fond of it. 



4 It is very injurious to a wheat crop, but may readily be avoided, as 

 it is sown along with the seed. Mr. Pitt.
