MAKING A TENNIS COURT
The largest item in all the estimates for making a tennis court is for labour. If a boys' club can supply this they can have a court without expense except for the wire netting and the necessary posts. A standard double court is seventy-eight feet by thirty-six. Choose a well-drained piece of ground; the more nearly level the better. Locate the courts with reference to the time of day when they will be most used and the direction of the sun's beams at that hour.
The first job is to get rid of the grass and weeds, root and branch. If a plough is used do not begin the levelling until every root is gone. Turning grass under is bad practice. Some kinds of grass can grow no matter which end is up. Next with rakes make the surface fairly level. Level is one of those adjectives that can not be compared. If a court is level it can't be any leveller, and to be right it must be done with a straight edge and a spirit level. If there is one boy in whom you all have confidence, it is a good plan to elect him boss of the job and follow his instructions. "Team work" is the right thing in this kind of a job, just as in games. When the court is level it must be rolled and rolled and rolled again, with the heaviest roller you can get.
A surface of ordinary dirt does not wear well. Some people prefer to spread on a layer of ashes, next three inches of sand, soil, and clay mixed.
Roll each layer thoroughly. For a top finish a very fine gravel is used on some courts, sand is used on others. You will probably use that which is most available. Clay is hard to work with, but when overlaid with fine sand makes a hard court on which the swiftest experts can play with enjoyment.
The care of the court should be taken week about, two boys working together. The roller should be used often, especially after a rain, and worn spots mended immediately before they get bigger.
Most clubs count in an expensive marker when estimating the cost of tennis. An ingenious boy can make one for nothing. A square varnish tin or olive oil can holding a gallon or more can easily be held by a framework upon a wheelbarrow or wheel hoe in such a way that the drip from two nail holes will fall upon the broad rim of the wheel. Fold a piece of paper into funnel shape, fill the can with thin whitewash and paint mixed and you are as well equipped as if you had spent five dollars for a marker.
If conditions favour a grass court the sod should be taken off and the ground beneath spaded, raked, and made level. Then the sod should be matched and laid accurately, then rolled, sprinkled, and rolled again; for three days at least the rolling and sprinkling should be repeated.
