Every good system has its weak point, and the weak point of this one is, that it is essential to its success that the set which comes back from adjustment is the identical one which was sent. I do not suggest that the leading makers would knowingly make a mistake of this kind; on the contrary, I know as a fact that great care is taken in the turning shop to prevent any such accident; but one set of balls is very like another, and it is quite possible that an unintentional change might take place. However, with a view to render such an accident impossible, one firm, at any rate, willingly allows the man in charge of the balls to stay in the shops while they are being adjusted, so that he can take them away with him as soon as they are finished.
If neither of these systems is adopted, the best plan is to buy the balls for the ensuing billiard season in the early summer, when little or no play is going on, and keep them in the room seasoning until they are wanted in the autumn. Any time and trouble expended on their careful selection will be amply repaid before the year is out, because the balls so selected will have hardened up, and will be less liable to crack than others bought a few days before they are required for regular use.
Balls purchased from, or adjusted by, a first-class firm should not require to be tested for size and weight, because they have been accurately gauged (fig. 26) and weighed before they are sent out; but a rough-and-ready test may be useful if one finds oneself about to play in an out-of-the-way corner of the country, and one half suspects the presence of the inevitable pool ball. Place the three balls in a line touching one another and one of the cushions, and then lower the eye till the line of sight becomes a tangent to the top of the balls and the top of the woodwork of the cushion; by this means irregularity in size is easily detected. If you suspect the balls to be foul, set up balls 2 and 3 touching; note the exact spot on cushion where 3 should hit—viz. that indicated by the prolongation of a line through the centres and point of contact.
Then play the plant with ball 1 and note deviation. If in doubt whether balls or table be in fault, reverse the stroke; go to the opposite end of the table and play back over the same line. Good lines to select are the diagonals which are the longest on the table.

‘How can you tell a good ball?’ is a question that is often asked, and the late Mr. Frank Buckland answered it as follows. ‘The test is this: the ball is rolled gently along a billiard-table till it stops of its own accord. If at that moment it falls either to one side or the other, it is useless to the player; if, on the contrary, it remains motionless on the same line on which it was originally projected, it is allowed to pass muster.’ Such a test, however, would be too much for 99 balls out of 100. First, ivory is not like Whitworth steel; it is a substance of varying density, and even if by the skill of man it could be turned into an absolutely perfect sphere, it is hardly likely that the centre of gravity of each piece would coincide with the centre of the sphere; secondly, in order to make the experiment at all satisfactory, the table should be absolutely level, the cloth perfectly new, free from dirt, of the finest quality, and most carefully stretched; and, lastly, the ball must be struck exactly on its vertical centre line. Each of these conditions presents some difficulty in attainment; to combine them all is well-nigh impossible.
Every ball, to speak generally, will fall over a little, and it may be due to the failure of any one of the above conditions. Therefore, it is safer to say that the less a truly struck ball changes its horizontal axis the better ball it is. For the owner of a private table, I should say the safest way to get a good set is to ask a first-class professional player, whom he can trust, to make the selection; of course he would have to pay a good price, but he will no doubt thus get a better set than he himself could choose. If he should in this way become the fortunate possessor of a good set, he ought to lock them jealously away, only to be produced when he finds an adversary that he can trust with them; and he will find it good policy to keep another set for ordinary use.
Ivory is getting increasingly scarce, and everything seems to point to the fact that as time goes on good balls will become still more costly, and more difficult to procure; and one is led to the conclusion that the next generation will have to find some substitute, or leave billiards to millionaires. Many attempts have been made in the last few years to get over the difficulty, and composition balls of various substances have from time to time been placed upon the market; but the earlier kinds have not found much favour—first, because they were believed to be explosive; secondly, because they did not possess sufficient elasticity; and, lastly, because they showed a tendency to soil, and pick up any dirt they might happen to pass over.
About the year 1893 or 1894, however, a new composition called Bonzoline made its appearance. The makers claim for it that it is heavier (specifically) and more elastic than ivory, and, as far as observation at present goes, their claim seems to be well founded. Whether bonzoline will stand the wear and tear of everyday work as well as or better than ivory it would be premature to offer an opinion, but these balls have at least the merit of cheapness: 31s. 6d. compares very favourably with 3½, 4, or 5 guineas for a set of balls; so that, even if they do not last so long as ivory (and I do not say they do not), a purchaser would not be very much out of pocket thereby. One thing is certain, that they run very truly at first, and time will soon show whether they can be depended upon for endurance. They certainly do not appear to be explosive; they seem less affected by changes of temperature and damp than ivory; but they have the same facility for picking up dirt that the older kinds had. I cannot, however, find that washing them in tepid water injures them in the slightest degree. For pool and pyramids they represent an enormous saving in money.
