The wood pieces forming the parts of the chair 

 slip together without nails like a puzzle 



by checking and notching the several parts.

 of wood 5 in. long by 2^4, i'l- wide and i $ in. 

 thick. The sides are 7J^ in. long, '^ut from 

 a 3/^-'n- board, 14 in- thick. iiach of 

 these pieces is grooved for the back and 

 cross-grooved for the top and bottom part 

 of the box. The outline of these pieces \i

 of the part that receives the front and 

 back is 234 '"• wide. The front and the 

 bottom parts are shown at the right and 

 left in the illustration, and are 3 in. long 

 by 2}/2 in. wide. Each is cut from 3 -i ■in- 

 board, which is left full thickness at the 

 ends; but in the center across the trhole 

 breadth it is reduced to }'§ in. thick for a 

 length of 2^4 in- The seat of the chair is 

 cut and checked the same way and to the 

 same size and has the addition of the 

 coin slot. The bottom which is shown in

 ture in the locality where this 

 is in use frequently reaches 

 40 deg. below zero. The house

An ordinary box stove for 

 4 ft. cord wood is built into 

 a rectangular jacket with 

 walls 8 in. thick. An air- 

 space of 8 in. separates the 

 concrete from the stove at 

 the nearest points. The top 

 of the wall is recessed so as 

 to \vd\e a 4-in. shelf to 

 support the galvanized sheet- 

 steel roof. This steel top 

 has sleeves for the smoke-pipe 

 and heat Hues, and is supported by two 

 iron bars, equally spaced between the ends. 

 The front of the stove is built in flush 

 with the concrete, allowing access to fire 

 and ash-doors. The expansion of the stove 

 is provided for where it passes through the
