Answer. It is best adapted to grass and every kind 
of summer grain. 
Query 8. When is the best time to scatter it ? 
Answer. The time to strew it is in the spring, when 
vegetation is fairly abroad. 
Query 9. What is the greatest product per acre of 
grass, &c. you have known by the means of plaister? 
Answer. Respecting the quantity of grass per acre, I 
have answered above. 
Query 10. Have you ever used it with other manure, 
and what ?—and the effects if any superior to the piais- 
ter alone ? 
Query 11. Is there any difference between the Euro- 
pean and American plaister ? 
Answer 10 and 11. I answer in one: have never used 
it with other manure ; thought inexpedient.* 
As to its durability, the product for five years, mowed 
twice each year, and the third. plaistered, will I believe 
be more than can be produced from dung, without re- 
striction of quantity. 
* T am sorry I have not had the pleasure of a conversation 
with Mr. West since he was so obliging as to communicate 
his answers. I was obscure in stating to him the 10th query. 
I meant not a mixture of the gyps with the dung, and a ‘cotem- 
poraneous application. He has in his answer to the 6th query 
met my ideas on the subject.
