While playing, either a match or practice sets, never under any circumstances drink anything. It is bad on general principles to drink when overheated, and while exercising in this way cold drinks will surely make a player feel badly, and eventually give him dyspepsia, if nothing worse. It is well to have a pail of fresh water--better still, oatmeal water--near the court, and there is no reason why the players should not occasionally wash out their mouths. In England, where there is even a greater fear of ice-water than there is among our own sensible people, tennis-players frequently take a little warm tea between sets when playing important matches. The tea, which is served not hot but only lukewarm, quenches the thirst very satisfactorily, and, in addition, acts as a stimulant to the system. After an afternoon of play on the courts it is a very good thing to retire to your room and use a pair of light wooden dumbbells for two or three minutes. This exercise is not fatiguing and does not take up any time, and makes a man feel refreshed and somewhat rested, for it brings into play a number of muscles that were not used on the court. It goes without saying that bathing is imperative after tennis, as it is, after all, exercise, and after the bath a rub down with a rough towel. The man who takes a cold bath in the morning will find himself better set up for the coming day's play, and it cannot be too strongly urged upon players at the sea-side to take a plunge before breakfast, if they can, in the salt water. To lay a grass court is not such a difficult matter as it might seem to one who has never attempted it, and as some of the readers of this Department seem to wish to be enlightened on this subject, it may be well to devote a few lines of explanation. We will suppose, of course, that the grass court is to be laid out on a lawn, and not on a bare space that must be sodded down. The portion of the lawn selected should be, of course, as flat and even as possible, and the court should be carefully measured out, but not necessarily marked out, before anything else is done. Then with sharp spades remove entirely all the existing turf. When this has been done the bare ground must be properly levelled and turned over, and a layer of fine soil about two inches deep should be laid on. Then replace the turf and beat it well down. It sounds like a heavy undertaking to remove the sod from the entire court space, but the results will justify the labor expended, and the court will be a much better one when completed than if the rough spots only had been taken up and smoothed over.
