urged that the standard size court be used in all match games, where possible. 

 The court shall be bounded by well defined lines two inches in width, and 

 which shall be at every point at least three feet from walls or any obstruc- 

 tions. The lines on the short sides of the court shall be termed the 'end 

 lines,' those on the long sides the 'side lines.' A center line, two inches in 

 width, shall be drawn on the court immediately beneath and parallel to 

 the net. 



The net shall be three feet wide over all and of sufficient length to reach 

 from side line to side line. It shall be made of a four-inch square mesh of 

 black or dark brown No. 30 thread. The net shall be bound top, ends and 

 bottom with one-quarter-inch rope. A double thickness of white canvas, 

 two inches wide, shall be sewed to the top of the net through which shall be 

 run a wire cable one-quarter inch in diameter. The net shall be tightly 

 stretched by the four corners between walls or uprights which are entirely 

 outside the court, and it shall cross the 

 court midway between the end lines and 

 parallel to them. The cable shall be 

 drawn so as to permit as little sag as 

 possible and the top of the net shall be 

 level and measure eight feet from the 

 center to the ground." 



It is recommended that for chil- 

 dren and also for women, the size of 

 the court be reduced to 25x50 feet, 

 and that the top of the net be from 

 seven to seven and a half feet from the ground, depending upon the ages 

 of the players. 



Running tracks. The running track is an essential feature of an athletic 

 field, although on account of the space it requires, and the maintenance and 

 construction cost, it is frequently omitted from neighborhood playfields. 

 Among the most important considerations in track construction are tem- 

 perature, rainfall and soil bed. Although these vary in different sections, the 

 following suggestions should be helpful. Many of them are taken from the 

 replies to a questionnaire sent out to more than fifty university track 

 coaches and compiled by H. F. Schulte of the University of Nebraska. 1 

 "It appears to be generally accepted that a well-constructed running track 

 should be put down in three layers or strata: (i) A coarse layer, consisting 

 of coarse rubble, stone or clinkers. This should be leveled and heavily rolled. 

 (2) A middle layer of straight-run cinders of rather coarse grade, but with- 

 out heavy clinkers. This must be well rolled. (3) The top-dressing, a finely 

 screened cinder mixed with clay, black loam or coal ashes." 



For the rough fill crushed stone is generally preferred, although some
