They had seen him many times, and had imitated the motion on shore, first putting the flat hands together, thumb to thumb; the thumbs in their natural position, and not held under the palm; the tips of the thumbs crossing (as sculls cross in sculling); the fingers together, but not squeezed tight, a little interstice between them matters nothing, while if always squeezed tight it causes a strain on the wrist. The flat hands thus put together held four to six inches in front of the breast, and then shot out--not with a jerk, quick, but no savage jerk, which wastes power--and the palms at the extremity of the thrust turned partly aside, and more as they oar the water till nearly vertical. Do not attempt a complete sweep--a complete half-circle--oar them round as far as they will go easily without an effort to the shoulders, and then bring them back. The object of not attempting a full sweep is that the hands may come back easily, and without disturbing the water in front of the chest and checking progress, as they are apt to do. They should slip back, and then the thumbs being held naturally, just as you would lay your flat hand on the table, they do not meet with resistance as they do if held under the palm. If the fingers are kept squeezed tight together when the hands are brought back to the chest, should they vary a hair’s breadth from a level position they stop progress exactly like an oar held still in the water, and it is very difficult to keep them absolutely level. But if the fingers are the least degree apart, natural, if the hand inclines a trifle, the fingers involuntarily open and the water slips through, besides which, as there is no strain, the hands return level with so much greater ease. The thrust forward is so easy--it is learnt in a moment--you can imitate it the first time you see it--that the bringing back is often thought of no account. In fact, the bringing back is _the_ point, and if it be not studied you will never swim well. This he had told them from time to time on shore, and they had watched him as he swam slowly by them, on purpose that they might observe the manner. But to use the arms properly on shore, when they pass through air and meet with no resistance, is very different to using them properly in the water. Bevis had to stand facing the shore in water as deep as his chest; then to stoop a little--one foot in front of the other for ease--till his chin nearly rested on the surface, and then to strike out with his arms. He was not to attempt anything with his feet, simply to stand and try the stroke. He put his flat hands together, pushed them out, and oared them round as he had often done on land. As he oared them round they pushed him forward, so that he had to take a step on the bottom; they made him walk a step forward. This he had to repeat twenty times, the governor standing by, and having much trouble to make him return his hands to his chest without obstructing his forward progress.
