ground. It is indeed true that there are aiways arising, 

 in the construction, exigencies which require this addi- 

 tion, tliat omission, or an entire change. It becomes, 

 then, all the more important that, in all things where it 

 is at all possible, a predetermined scheme shall be fol- 

 lowed. The ideas of the author, conscientiously worked 

 out in some parts, give a definite suggestion for the con- 

 cordant treatment of otlier parts to which his foresight 

 could not have extended. Nor is it a sufficient excuse 

 for changing any detail of a plan that some other item 

 seems at the time to be better than the one originally 

 proposed, even though it be to introduce some new and 

 beautiful plant not known to the artist. Only a few of 

 these changes are required to alter conspicuously the 

 original idea, and possibly to destroy forever the unity 

 of its expression. 



Even in the smallest compositions, such as the

 that it received its first great development at the hands 

 of the English gardeners ; and the latter is often known 

 as the Italian style, from having been brought to a high 

 degree of perfection by Italian artists. It is quite possi- 

 ble to conceive of other legitimate styles, and room is 

 accordingly made for a method of treatment not seldom 

 employed, called here the picturesque style. This is 

 neither '' natural," in the sense of belonging to the Eng- 

 lish school, nor in the least architectural. It is not 

 commonly spoken of as a distinct style ; yet it seems 

 better to treat it here as such, and to point out that 

 there may be other distinctive styles adopted in special
