Of course, the preceding remarks apply to clear water and will not hold good where the water is con- tinually agitated and clouded by mud or refuse. Swirling water usually indicates a shoal or some submerged obstruction or may be the result of a divergence of current.
When ready to cast off from the mooring, haul in the slack on the dinghy's painter to prevent the bight from dropping into the water and fouling the propeller. Test the engine to make sure that it is running and that the clutch is workin g properly, and let go. Allow the boat to drop back from the mooring enough to allow you to clear it and then start ahead, taking care that you do not veer off so sharply that the stern of the boat will foul in passing the buoy or dock.
"The Rules of the Road" are published in booklet form by the Steam Boat Inspec- tion Service and give complete instructions as to the proper equipment for motor-boats of various sizes. Four units, however, should be included on every craft whether large or small; they are, a good heavy- anchor and at least 150 feet of good heavy line to use with it; plenty of life preservers; a good substantial whistle or fog horn and the necessary lights to be used at night.

When, passing a boat load of timid women and children slow your boat down rather than cause the wave from your wake to fright- en them or maybe capsize them.

A little extra care and attention when laying ft up for the winter or even when it is to be out of commission only a few weeks or days will prevent a variety of troubles later on.
