being the materials most commonly used. When tile, brick or marble, 

 are used, they should be set in cement and laid upon a well rein- 

 forced concrete foundation. Even with these precautions the joints 

 often loosen during the season of alternate freezing and thawing. 



A floor of concrete colored a turkey-red and marked off like tile 

 makes an attractive and inexpensive floor. Often the outer edge of 

 the floor can be left in the natural concrete with the colored concrete 

 in the center. A flagstone floor placed upon sand will prove attractive 

 and durable. 



When the garden paths connect with the garden house they can 

 often be widened, forming the garden floor. These might be, in ad- 

 dition to the materials already mentioned, of gravel, macadam o r 

 even grass, although grass will be found the least desirable of all of 

 these 



Often in ravines where bridges and railings along paths are made 

 of rustic work, a house of the same material would be in keeping, 

 although it may be frankly stated that rustic work brought into well-kept 

 areas where other types of construction are visible, would hardly be 

 considered advisable. 



PERGOLAS 



The earliest examples of the pergola were used along pathways, 

 and they are best to-day when used as a connecting feature between 

 two buildings or two garden motifs. A pergola may, however, furnish 

 a terminal motif at the end of an axis, a central motif of a formal or 

 informal area, or the major part of some comprehensive architectural 

 scheme. Whatever the situation, however, a pergola should be con- 

 structed of the best weather-resisting materials available; and, further, 

 there are a few structural precautions which must be observed. 



The columns should be made of staves joined together in some 

 good interlocking method, for one thing, and built up that they may 

 withstand the ravages of the elements. The capitals should be cov- 

 ered with either zinc or copper in order to protect the top. The base 

 should be made of metal also, as a wood base resting upon a concrete 

 foundation soaks up the moisture and is short-lived. The foundation 

 for the column, made of concrete preferably, should go down below 

 the frost line, which is about three feet below the surface of the ground
