How to See the Wind.
' Take a polished metal surface of two feet or more, with a straight edge ; a large handsaw will answer the purpose. Take a windy day for the experiment, whether' hot or cold, clear or cloudy ; only let it not be murky, rainy weather. Hold your metallic surface at right angles tq the direction of tJie wind—i.e., if the wind is north hold your surface cast and west, butinst'oad of holding it vertical, incline, it 42 degrees to the horizon,"so'that the'wind, striking, glances and flows over the edero, as the water flows 'over a dam. Jfow^ sight carefully along the odge some minutes, jat a sharply defined obje<j£, and you will see the wind pouring over thp edge in graceful curves, Make your observation carefully, and you will hardly- ever fail, in your experiment. The results are even better if the sun is obscured. —" St Louis Republic."
