 subsoil plough without bringing the poor soil to the 

 top, and the good surface soil can simply have the 

 sods turned over to rot. 



After thorough preparation of the soil, including 

 a plentiful supply of fertilizer, the small tennis court 

 may be sodded to insure quick growth of turf for 

 use the first season. When seed sowing is prefer- 

 able, for larger courts, fall seeding will form a good 

 turf for the following spring. 



Various chemical fertilizers are used for soils 

 rich in humus, when it is difficult to obtain barnyard 

 manure. Peruvian guano, agricultural lime, ground 

 bone, superphosphate of lime, nitrate of soda, etc.,

 mixed in various proportions according to the 

 amount of humus in the soil. For the tennis court
