have heen elevated by the slide (if it is anything over 4 inches) to a height over which the oar-handle cannot pass without heing elevated in its turn. Therefore, having once made his eatch with rigid knees, the pupil should then begin to slide, contemporanéously with his swing, for a smal! distance, until he has brought his knees to such a level that the oar-loom can pass over them (No. 2, p. 110), He should during this period of the stroke slide only just so much as is required in order io bring his knees to the necessary height before the oar reaches them. By the time that the oar comes over them he will be about the perpendicular (No. g, p. 111). Now comes that part of the stroke which, on a slide, is the most effective. ‘The body should from this point swing well back, much further so than would be orthodox upon a fixed seat ; all the time that the body is thus swinging back the legs should be extending, and the pace of extension should be regulated according to the length of slide. In any case the slide and swing should termi- nate contemporaneously (No. 4, p. 111). The arms, as in fixed-seat rowing, should contract and row the stroke home while the bedy is still swinging back. They should not begin to bend until the trunk has well passed the perpendicular.
The oarsman must hear in mind that the moment for finishing his slide should be regulated, not by the length of the stide, 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 to inches or more, and he decides, either from fatigue or hecause he need not fully extend himself, to use only part of his slide; or suppose he is changed from a boat fitted with Et-inch slides to one with g-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 stide, and will bring it to an end before the swing is completed, thus rendering the latter part of the swing helpless fur want of due leg-support. If slide and swing are not arranged contemporancously, it is far better
