ARRANGEMENT OF WALKS AND DRIVES 319 



can be drained, but space will not permit of a discussion of 

 the various methods. In case any complicated conditions 

 arise that cannot judiciously be handled by the owner an 

 engineer or a drainage expert should be consulted. The best 

 plan, however, is not to select a poorly drained piece of land 

 on which to build a residence. The drainage will be largely 

 determined by the nature of the subsoil, and when you are 

 selecting the building site due consideration should be given 

 to the type of subsoil which underlies the top soil. If the 

 subsoil is comparatively close to the surface and composed of 

 heavy impervious material in the nature of a hard pan the 

 drainage will be poor and in all probability the only relief 

 will be to tile drain. If, on the other hand, the subsoil is com- 

 paratively deep or is composed of loose material the drainage 

 will be more perfect and will usually form an ideal site, so 

 far as this phase is concerned.

Arrangement of Walks and Drives. — On small city lots the 

 walks and drives should be the shortest distance between the 

 two points, namely, the outside walk and the door-step. 

 Likewise it would be pure folly to construct an automobile 

 drive in any other manner than to have it go directly from the 

 street to the garage in a straight line. However, the method 

 of constructing walks and drives differs when we consider 

 the suburban home or the country place, and in these cases 

 the walks and the roads must be viewed from a different 

 aspect.
