When the weather is very cold, the tent may be made warmer by excavating a basement about three feet deep, which also gives a wall to the tent, making it more roomy. The tent used in the army will shelter comfortably twelve men. Captain G. Rhodes, of the English army, in his recent work upon tents and tent-life, has given a description of most of the tents used in the different armies in Europe, but, in my judgment, none of them, in point of convenience, comfort, and economy, will compare with the Sibley tent for campaigning in cold weather. One of its most important features, that of admitting of a fire within it and of causing a draught by the disposition of the wings, is not, that I am aware, possessed by any other tent. Moreover, it is exempt from the objections that are urged against some other tents on account of insalubrity from want of top ventilation to carry off the impure air during the night. CAMP FURNITURE. The accompanying illustrations present some convenient articles of portable camp furniture. [Illustration: CAMP CHAIR. NO. 1.] CAMP CHAIR NO. 1 is of oak or other hard wood. Fig. 1 represents it opened for use; in Fig. 2 it is closed for transportation. _A_ is a stout canvas, forming the back and seat; _b_, _b_, _b_ are iron butt-hinges; _c_, _c_ are leather straps, one inch and a quarter wide, forming the arms; _d_ is an iron rod, with nut and screw at one end. [Illustration: CAMP CHAIRS. NOS. 2 AND 3.] CAMP CHAIR NO. 2 is made of sticks tied together with thongs of buckskin or raw hide. CAMP CHAIR NO. 3 is a very comfortable seat, made of a barrel, the part forming the seat being filled with grass. [Illustration: CAMP TABLE.] CAMP TABLE. Fig. 1 represents the table folded for transportation; in Fig. 2 it is spread out for use. _A_ is the top of the table; _a_, _a_ are side boards, and _c_, _c_ are end boards, turning on butt-hinges, _b_, _b_, _b_. [Illustration: FIELD COT. NO. 1.] [Illustration: FIELD COT. NO. 2.] FIELD COTS. In No. 1, _A_ represents the cot put up for use; _B_, the cot folded for transportation. The legs turn upon iron bolts running through the head and foot boards; they are then placed upon the canvas, and the whole is rolled up around the side pieces. In No. 2 the upper figure represents the cot put up for use; the lower shows it folded for transportation. _A_ is a stout canvas; _b_, _b_ are iron butt-hinges; _c_, _c_, the legs; _d_, _d_, leather straps, with buckles, which hold the legs firm; _f_, _f_, ends, which fold upon hinges; _g_, _g_, cross-bars from leg to leg.
