Example D is of a class which occurs occasionally in actual play. Balls 1, 2, 3 are nearly in a straight line, ball 3 being about 2 in. from the side cushion, so that a ball cannot pass between. An ordinary following stroke is difficult and uncertain, so usually the best play would be to give a miss; but the state of the game may render that impossible or undesirable, in which case the best chance of scoring is to strike down on ball 1, causing it to leap on to ball 2, which in turn bounds away, leaving the course clear for ball 1 to reach ball 3 and make the cannon either direct, off the side cushion, or even possibly from the top cushion.
The effect of ball 1, so struck, causing ball 2 in turn to leap, is prettily shown by placing the pool basket and balls as drawn in Example E. A smart stroke down on ball 1 will cause ball 2 to jump into the basket.
Many examples of fancy strokes made by means of the leap could be given, but they are purposely withheld, as there is no wish to encourage experiment as useless to the game as it is detrimental to the implements.

Piqué and massé are not often used in English billiards; the latter, indeed, seldom or never, whilst the former, when used, is miscalled massé. They form in reality a continuation of the series of strokes which, departing from the normal or horizontal, culminate in one delivered vertically on the top of the ball. Thus, in fig. 1, Q, Q′, &c., represent the axes of a cue presented at various angles to the ball whose centre is C on the table T T. It has already been explained, but may without harm be repeated, that, the strength of stroke being equal, the maximum forward motion to the ball, or translation, is given by the horizontal delivery of the cue on the line Q C. As the angle of delivery increases, so does the forward impulse decrease until the limit 90°, or a vertical stroke, is reached, when there is manifestly no forward motion communicated to the ball, the entire force of the stroke being counteracted by the rigidity of the table. Now, without any attempt at fine distinction or any claim to precise accuracy, it may, in a rough way, be said that plain strokes are delivered on the axis Q C; that stabs lie between that and Q′ C, which is at an angle of 45° with Q C, or half-way to the vertical; that piqué commences at Q′ C and ends at Q″ C, beyond which the strokes are termed massé. This is not exactly correct, for there may be a massé with less inclination than Q′ C, the real distinction between piqué and massé being that in the former the cue’s axis is directed to the centre of the ball, and therefore the effect is to drive it straight with reverse or retrograde rotation; in the latter, the cue’s axis is not directed through the centre, but on one side or other of it, with the consequence that the path of the ball is no longer a straight but a curved line. This is the case to such an extent that the rotation round an oblique axis will often conquer the small measure of translation or displacement conveyed by the stroke and produce some beautiful curves.
Now, so long as the push stroke is allowed, massé will not be much attempted; it is difficult of execution at any time and in any position, impossible on a large English table save when the balls are near a cushion. It further has the great disadvantage, when played hard, of causing a dent or pit in the cloth sufficient to deflect or arrest a very slow ball, and therefore soon spoils a cloth near the cushions on the very part most used for nursery cannons. It is also doubtful whether with the most skilful manipulation effect can be got with small balls and fine-pointed cues at all equal to that which is obtained in the French game. Hence for many reasons we are indisposed to recommend the study and practice of this undoubtedly beautiful stroke.
Quite otherwise, however, with piqué, which may often be used with advantage in the English game and without harm to the table. The stroke is indispensable when ball 1 is so near ball 2 that the screw back cannot be made in the ordinary way, or when the cushion prevents the application of the cue to the proper part of the ball. In Diagram XVI. a few examples are shown. A learner should get some person who can make them—and they are all very simple—to play the strokes before him once or twice, when he will observe that no great strength is required: the weight of the cue let drop on the right part of ball 1 will almost do what is needed, and by restraint of force the danger of cutting the cloth is greatly reduced. More harm is done by hitting the ball hard vertically, for then the cloth is damaged in the same way, though not so badly as when a careless or thoughtless person in spotting the red ball, finding that it has a tendency to move on the spot, hammers it down with force, thus in a very short time forming a cup sufficient to ruin all delicate play from the spot, and with a hard stroke very likely to cause the red ball to fly off the table. The practice is most reprehensible, and persons doing it should invariably be remonstrated with, for they are ruining the table for more intelligent players.
