_Swing._--faults of may be various. There may be a hang, or conversely a hurry, in the swing; and, as shown above, the causes of these errors in swing may often be beneath the surface, and be connected with faulty hold of an oar, or a loose or badly placed strap, or a stretcher of wrong length, or from faulty finish of the preceding stroke. Lateness in swing may arise _per se_, and so may a 'bucket,' but as often as not they are linked with other faults, which have to be corrected at least simultaneously, and often antecedently. _Screwing_ either arises from mechanical fault at the moment or from former habits of rowing under difficulties occasionally with bad appliances. If a man sits square, with correct oar, rowlock, and stretcher, he does not naturally screw. If the habit seems to have grown upon him, a change of side will often do more than anything else to cure him. He is screwing because he is working his limbs and loins unevenly; hence the obvious policy of making him change the side on which he puts the greater pressure. _Feather under water._--The fault is one of the most common, the remedy simple. The pupil should be shown the difference between turning the oar-handle before he drops it (as he is doing) and of dropping it before he turns it as he ought to do; and it should be impressed upon him that the root of the thumb, and not his knuckles, should touch his chest when the oar comes home, and should be done _before_, and not after, he has dropped his handle to elevate the blade from the water. If a crew feather much under water, it is a good plan to seat them in a row on a bench, and give each man a stick to handle as an oar. Then make them very slowly follow the actions of the coach, or a fugleman. 1. Hands up to the chest, root of thumb touching chest. 2. Drop the hands. 3. Turn them (as for feather) sharply. 4. Shoot them out, &c. Having got them to perform each motion slowly and distinctly, then gradually accelerate the actions, until they are done as an entirety, with rapidity and _in proper consecution_. The desideratum is to ensure motion No. 3 being performed in its due order, and _not before_ No. 2. Five minutes' drill of this sort daily before the rowing, for a week or two, will do much to cure feather under water even with hardened sinners. _Swing across the boat._--This is an insidious fault. The oarsman sits square, while his oar-handle moves in an arc of a circle. He has an instinctive tendency to endeavour to keep his chest square to his oar during the revolution of the latter. A No. 7 who has to take time from the stroke by the side of him is more prone than others to fall into this fault. The answer is, let the arms follow the action of the oar, and give way to it, and endeavour to keep the body straight and square. Keep the head well away from the oar, and its bias will tend to balance the swing.
