The principal feature of the park should he grandeur, and the

 And the smooth asp in soothing whisper plays, 

 The lir that blooms in spring's eternal prime, 

 The spiry poplar and the stately lime."

 come of it. 



It is therefore upon this account that they bestow the pains 

 they do in the culture of it, ploughing, harrowing, and breaking 

 the clodded lumps of earth. 



It is the same way that sea salts, nitre, and other salts promote 

 vegetation; and he says he is sorry that he cannot subscribe to 

 the opinion of those learned gentlemen, who imagine that nitre is 

 essential to plants, and that nothing is acted in the vegetable 

 kingdom without it. 



For by all the trials he has been able to make, the thing is 

 cpiite otherwise ; and when contiguous to the plant, it rather 

 destroys it than otherwise. 



But this nitre and other salts certainly do ; they loosen the 

 earth, and separate the concreted parts of it; and by that means
