After the evening meal there usually comes a lull in the duties of Brownie camp life. Pickets have been told off and stationed at their posts, camp fires are kindled, and the soldiers gather around the glowing light, stretched upon the grass underneath the shadow of leaves and flowers, or seated on rude stools of pebbles and twigs. In chat and story they forget the fatigues and dangers of a soldier's life. They spin yarns of past adventure, tales of "moving accident by flood and field" and "perils in the imminent deadly breach;" they discuss the chances of the campaign, the strategy and behavior of the enemy, and the merits of their commanders. Jokes, quips, merry anecdotes and witty sayings run around the circle, and ever and anon hearty peals of laughter break out upon the still evening air. "Ho, lads! Tone down your mirth a bit!" cried the officer of the day to one of these groups, in the camp before Fort Spinder. "Aye! aye, Sir!" was the response, and for a moment silence fell upon the circle. "Say, boys," at last exclaimed one of the company, "let's get out of this and go for a lark. I have a capital idea in my head." "Ho, ho!" cried Brownie Highjinks; "Twadeils really has an idea in his head! I'll warrant it's a lively one. Out with it! I'm for any fun that's not against general orders." "Well then, lads, come close together and listen." Twadeils was one of two brothers who had got their somewhat peculiar name from their daring and mischievous spirit which kept them and most people around them in a whirl of excitement and adventure. Their chums nicknamed them the "Twa deils," and the two words at length became one, and the lads were called Twadeils Senior and Twadeils Junior. But among their fellows they were simply known as "Twadeils" and "Junior." The Brownies grouped themselves around Twadeils, heard his plan, and with little question gave hearty assent. An hour and place of meeting were fixed; and after discussing details of the proposed lark in whispers as they bent over the camp fire, the merry plotters retired to their tents. In due time they were up and assembled at the rendezvous. The group that now started out upon their secret adventure was made up of Brownies from all arms of the service. The navy was represented by Brownies Barck, Ferrie, Wetman and Obersee; the cavalry by Brownies Gear, Saddler, Martingale, Hosson, Howrode and Barnit; the infantry by Halfrick, Highjinks, Esslade and the two Twadeils. A merry crowd they were and as bold as merry. The story of their night adventure we are now about to tell.
