should be regulated according to the length of slide. In any case the slide and swing should terminate contemporaneously (No. 4, p. 111). The arms, as in fixed-seat rowing, should contract and row the stroke home while the body is still swinging back. They should not begin to bend until the trunk has well passed the perpendicular. The oarsman must bear in mind that the moment for finishing his slide should be regulated, not by the length of the _slide_, but by _the length of his swing_, and the latter should go well back until his body is at an angle of about thirty degrees beyond the perpendicular. Suppose he has a long slide, say of 10 inches or more, and he decides, either from fatigue or because he need not fully extend himself, to use only part of his slide; or suppose he is changed from a boat fitted with 11-inch slides to one with 9-inch ditto, he must not, when using the shorter slide, allow his legs to extend as rapidly as they did when they had a longer distance to cover. If he fails to observe this he will 'hurry' his slide, and will bring it to an end before the swing is completed, thus rendering the latter part of the swing helpless for want of due leg-support. If slide and swing are not arranged contemporaneously, it is far better that a balance of slide should remain to be run out after the swing has finished than _vice versa_. The legs can always push, and so continue the stroke, even if the body is rigid; but the body cannot conversely do anything effective for the stroke when once the legs have run their course.
