All fogs are due to this same cause, as well as that which, in extreme wintry cold, overhangs the open water, as it yields its comparative heat to the air. The formation and suspension of clouds, in all their varied characteristics, have the same origin. That highly attenuated haze which invests the distant landscape, particularly mountains, with its magical purple hue, is due to the same, but still more ethereal interposition of infinitesimal globules of suspended moisture. In corroboration of this being the true explanation of the phenomena of haze, fogs, etc., is the fact, that as soon as clouds prevail, denoting an electric change in the atmosphere, all haze immediately disappears, or becomes embraced in the larger vesicles or globules, forming clouds. FLY LEAVES FROM THE LIFE OF A SOLDIER. PART II.--CHEVRONS. She sewed them on upside down. Please to remember that this was in May, 1861 (or was it 1851? it seems a long time ago), when a young lady of the most finished education, polished to the uttermost nine, could not reasonably be expected to know what a sergeant-major was, much less the particular cut and fashion of his badge of rank. I told her, exultingly, that I was appointed sergeant-major of our battalion. 'What's that?' she inquired, simply enough. I explained. The dignity and importance of the office was scarcely diminished in her mind by my explanation; and, indeed, I thought it the grandest in the army. Who would be a commissioned officer, when he could wear our gorgeous gray uniform, trimmed with red, the sleeves wellnigh hidden behind three broad red stripes in the shape of a V, joined at the top by as many broad red arcs, all beautifully set off by the lithe and active figure of Sergeant-Major William Jenkins? As for Mary, who protested that she never could learn the difference between all these grades, or make out the reason for them, she was for her part convinced that not even the colonel himself, certainly not that fat Major Heavysterne, could be grander, or handsomer, or more important than her William. So I forgave her for sewing on my chevrons upside down, although it was at the time an infliction grievous to be born, inasmuch as the fussy little quartermaster-sergeant was thereby enabled to get a day's start of in the admiration and envy of our old company. How they envied us, to be sure! But I had one consolation: Oates' were all straight; mine were arched. And _she_ sewed mine on. His were done by Cutts & Dunn's bandy-legged foreman.
