course appear complete, thougli none of them will 

 be symmetrical. The formal scheme, presenting 

 one large and very obvious balance, may be seen 

 in its entirety at a glance. 



All design is based upon repetition, and aU de- 

 sign is consequently similar in so far as its appear- 

 ance is affected by the laws of repetition. The 

 diversity of the materials employed to express the 

 laws of repetition in different forms of design is 

 that which confuses the beginner. 



The laws of repetitionmay be divided into three 

 principal parts: sequence or simple repetition, 

 rhythm, and balance. 



A design should first of all possess tmity ; that is 

 to say, it should "hang together," and not appear 

 as a jumble of separate parts. This necessitates 

 at the outset a certain amount of repetition, and 

 in consequence it is necessary that some one ele-

 course, if too many elements are possessed in com-

 perfectly monotonous. Repetition applies to the 

 forms, sizes, colors, and positions of all materials 

 used (Fig. 15). 



It is not necessary that plant materials should 

 be alike in all respects, but oiily that more of their
