Suburban Home Grounds. 37 



damaging the turf edge. It is a very deceptive width to per- 

 sons driving and meeting another carriage as it looks wider 

 than it really is. A muddy drive is a poor introduction to the 

 home grounds. The surface drainage from the land adjoin- 

 ing the drive and the drainage of the drive itself may need 

 to be taken care of by means of subsoil drains. 



If the subsoil is clay or very wet, underdrains should be 

 used on the sides or in the middle of the drive. This is done 

 by digging a narrow trench 3 feet or 4 feet below the proposed 

 finished surface and laying 2 inch or 3 inch agricultural tile at 

 the bottom of the trench in such a slope that the water will run 

 through them. The joints of the tile should be covered with bur- 

 lap or tile collars used in addition to prevent the joints becom- 

 ing clogged. The water passes largely from the land into the 

 tile through the joint. In filling in the trench, first throw 

 some hay, stone, or inverted sod over the tile, then spread a 

 layer about 6 inches in depth of small field stone, broken stone, 

 or coarse gravel as an additional means of drainage. After 

 this is done the soil may be refilled and tamped with a rammer. 



The surface water can be taken care of by forming a groove 

 or turf gutter at the side of the drive or by building a narrow 

 gutter of stone or brick. 



If there is a large quantity of water flowing from the adjoin- 

 ing surface it may be necessary to use a catch basin. A very 

 economical way to build one is to use three lengths of vitrified 

 sewer pipe, 20 inches in diameter, set on end. On top, an iron 

 grating is set to fit into the bell of the pipe. The middle length 

 of the pipe should have a "T" outlet usually about 6 inches 

 in diameter. 



From this the drains can be connected and laid to the desired 

 point of discharge. Smaller sized catch basins can be built 

 to take care of a smaller flow of surface water. 



The joints of the pipe should be all sealed with cement mor- 

 tar, and it is a good plan to set the bottom upright pipe in 

 cement. This then forms a catch basin that will hold the debris
