On Plaister of Paris, 37 



was any time benefited, and I have reason to believe, 

 that it would have been as good a crop without the 

 plaister. I have never tried it on any other small grain. 



Grasses, I have generally used it on red clover. I 

 have also sown it on mixed grass, as white clover, blue 

 grass and timothy, always to good effect. 



Query 8. What is the best time to scatter it? 



Answer, I generally sow it in April, but have also 

 applied it in June, after mowing the first crop ; the effect 

 nearly the same. 



Query 9. What is the greatest product per acre you 

 have known by the means of plaister ? 



Answer, I once mowed eighteen tuns from five acres: 

 the clover was sown with oats on old ground ; the oats 

 was no more than a middling crop. Fifteen bushels of 

 plaister were sown after raking the stubble in Aprii, 

 and the grass cut the June following. 



I have frequently got two and a half tuns per acre, 

 never less than one and a half tuns ; the second crop is 

 generally one third less. I have indeed heard of much 

 more abundant crops of grass; but as I believe you do not 

 admit hear say evidence, I shall not trouble you with it. 



Query 10. Have you ever used it in connexion with 

 other manures, and what ? — does it agree with lime ? 

 and what effect has a connexion with other manures 

 produced superior to the plaister alone ? 



Answer, I have not used plaister in immediate con- 

 nexion Vvdth other manures till this spring. On about an 

 acre manured with barn yard dung, which was planted 

 with potatoes last year without dung, was sown barley 

 and clover, and immediately after three bushels of 

 N. S. plaister. I this spring also sowed barley and cIq^
