"If the moon rises clear expect fair weather." Right; because if it is summer even the eastern horizon would show the humidity necessary enough to cause a thunderstorm, and in winter the cirrus clouds give several hours' warning. But, again, the wind is the chief factor to be considered. Proverbs, representing variations of the truth, could be given about every manifestation of the skies as well as about things that were never manifest except in the imagination, for every country has contributed to the volume of weather-lore. But, unfortunately, neither age nor amount of repetition are as good as the truth and they should be discarded if they are false. The way to discard is not to repeat. The man who desires weather-wisdom should seek it with his eyes. His comparison will be that which he sees with that which he has seen, and he will soon form all the weather axioms he needs for himself. The local Bureau or the Bureau at Washington will answer all his inquiries, cheerfully, promptly, and free of charge. Of course there are things that the Bureau wants to know itself. It is very curious about the higher strata of air. Small balloons have carried very light instruments to an altitude of fifteen miles and brought considerable knowledge to earth, but each bit makes more knowledge imperative. The cry of "last frontier" hurts the adventurous, the exploring, the woods-loving as no other cry has power to hurt. With the Poles gone and Alaska in harness we are inclined to think that it is all over. We resign ourselves to our trammelling globe,--as the gold-fish do,--forgetting. But there is plenty of interest left. The birds must be brought back. Forests must be made and patrolled, and the air-ocean is still unknown. That, at any rate, has remained unspoiled by man. The seas have been charted and the mountains have been disemboweled, but the atmosphere is unconquered. More must be known. Squadrons of aëroplanes cannot ride out the gale until their pilots know all about the gale. Until that time there need be no cry of last frontier, for until that time the weather will continue to be our overlord, whose dominions are flaunted before the watcher on the porch and the runner on the trail. CONDENSATIONS Look for continued fair weather when: A gentle wind blows from the west, northwest, or a little south of west. The sun sets in a cloudless sky. The sunset is composed of light tints, inclining to red or yellow. The sunset is followed by a glowing and slow-fading western sky. The sun sets like a ball of fire (warmer). The sun rises out of a gray sky. The clouds are noticeably high for the season. The clouds rise on the mountains. The clouds have frequent breaks showing blue sky between. The puffy cumulus clouds show a lot of white. The cumulus clouds decrease toward nightfall. The winter sky is mottled with a northwest wind. The summer morning fog breaks before ten o'clock. The dawn is low.
