INSECTS also are very sensible of such Changes of Weather. Frogs croak more than ordinary, Worms creep out of the Ground, Moles throw up more Earth than usual, because such Weather is more agreeable to them; Hornets, Wasps, and Gnats, sting more frequently against wet Weather than in fair. Spiders are restless and uneasy, and frequently drop from the Wall, the humid Air getting into their Webs and making them heavy. But the surest and most certain Sign is taken from Bees, which are more incommoded by Rain than almost any other Creatures, and therefore, as soon as the Air begins to grow heavy, and the Vapours to condense, they will not fly from their Hives, but either remain in them all Day, or else fly but to a small Distance. XXIII. _If it begins to rain an Hour or two before Sun-rising, it is like to be fair_ before Noon, and so continue that Day, _but if the Rain begin an Hour or two after Sun-rising, it is like_ to Rain all that Day, _except the Rainbow be seen before it rains_. THIS is a short, clear, and easy Observation, and therefore I shall not dwell long upon it, but rather entertain the Reader with a few Observations on the Rainbow. Whenever it appears, things are thus circumstanced. The Spectator has the Sun behind him, and Clouds with the Bow in them before him. Sometimes there are two and even three Bows seen, but this is very rare. The Colours in the Bow are ranged in this Order, _viz._ Violet, Purple, Blue, Green, Yellow, Orange, Red. After a long Drought the Bow is a certain Sign of Rain, if after much Wet fair Weather. If the Green be large and bright it is a Sign of Rain, but if the Red be the strongest Colour, then it denotes Wind and Rain together. If the Bow breaks up all at once there will follow serene and settled Weather. If the Bow be seen in the Morning small Rain will follow. If at Noon, settled and heavy Rains; if at Night, fair Weather. The Appearance of two or three Rainbows shews fair Weather for the present, but settled and heavy Rains in two or three Days' Time. LUNAR Rainbows are sometimes, but very seldom seen, they are extremely beautiful, but much less than those that appear in the Day time, and a yellow, or rather a straw Colour prevails most. As they happen so seldom, they cannot well be reckoned amongst the Signs of Weather. But now, after speaking of so many different Methods of judging when rainy Weather will be of a short or long Continuance: Give me leave to describe two or three Instruments easily made, which will shew the Alterations of the Weather certainly, constantly, and early enough for most Uses.
