DRAINAGE OF BARN-YARDS, ETC. 183 



method of procedure is to construct a tile drain to carry 

 the water away after it enters the cellar. Another is 

 to cover the walls 'and bottom with a thick coat of 

 cement mortar to prevent water from entering. If 

 there is much soil water to contend with, it frequently 

 bursts through the coating used in the latter method, 

 and when the former is used, the cellar remains damp 

 even when the drain removes the free water which per- 

 colates through the soil and finds its way to the low 

 point in the bottom from which drainage is made. 



The proper plan to follow is to prevent water from 

 entering by means of a tile drain, which should be laid 

 entirely around the building 4 or S f<^^t distant from 

 the walls and nearly if not quite as deep as the floor 

 of the cellar. This drain should be of 4-inch tile laid 

 on an even fall of i inch in 16 feet, and connect with 

 a main which will carry the drainage safely away 

 from the house. By this method the ground about 

 the house as well as the cellar will be kept dry and 

 wholesome, and is the best known plan for securing a 

 dry cellar for a country house where natural drainage 

 is deficient. 



The underdrainage of the ground occupied by build- 

 ings and surrounding yards and gardens is often neg- 

 lected on the supposition that these grounds have 

 sufificient natural drainage, which is not always the case. 

 The filtration of all surface water through the soil of 

 the lawn, garden, and surrounding grounds in general, 

 and its reLval by the process of u„d.,drai„a|e, will 

 add much to the ease with which walks may be con- 

 structed and maintained, and to the satisfactory growth 

 of all useful and ornamental plants which contribute so
