Besides those men who do not claim their courts in the spring, there are numbers of men who do not use them except during a small part of the day. In fact the majority of the men use their courts only between the hours of four to six in the afternoon. Many men who do not own courts or who own poor courts are willing to play in the morning or earlier in the afternoon if they can have the use of a good court at those times. But although they may see dozens of courts unoccupied they do not feel at liberty to use them. Let it be understood that during the morning and until three or perhaps four o'clock in the afternoon every court is open to the first comer. That is, that ownership of a court consists merely of the right to have the exclusive use of a court between certain prescribed hours of the afternoon. Let any person have the right to use any unoccupied court between three and six, provided only that he be ready to yield the court to the owner in case he should wish to use it.
