of the field. The center of the side arches is five feet, nine inches from the 

 border and thirteen feet, four inches from the end of the field. The double 

 wicket in the center of the court is set parallel to the end lines and measures 

 eighteen inches in length and three and three-eighths inches between the 

 wires. The other arches should measure three and a half inches between 

 wires. The arches are made of steel and should not be less than seven- 

 sixteenths of an inch in 

 diameter, and are driven 

 into four by six by eight- 

 inch blocks of hardwood 

 and the blocks, in turn, 

 buried beneath the 

 ground so that they are 

 covered for about one and 

 a half inches. The arches 

 stand eight inches high. 

 The area should be 

 brought to a subgrade 

 approximately parallel to 

 and 10 or 12 inches below 

 the proposed finished 

 grade of the court. If any 

 fill is necessary it should 

 be very carefully built up 

 in thin layers and rolled 

 with a heavy roller. Tile 

 drains should be installed 

 at 10 or 12-foot inter- 

 vals in a heavy clay soil, 

 but may be at 2O-foot in- 

 tervals in a soil of a po- 

 rous nature. The trenches 

 should be back-filled with 

 coarse cinders, gravel or PLATE No. 121 



broken stone, to a level 



of the subgrade. The subgrade should slope at all points towards some one 

 of these drains. The whole area should then be covered with a layer of 

 coarse cinders, screened gravel or broken stone to a depth of about six 

 inches. A two-inch layer of finer material, followed by a light covering 

 through a quarter-inch mesh screen, is then applied. Each layer must be 

 thoroughly tamped or rolled as laid. The surfacing is now laid, usually from
