The floor plan drawing shows where each 

 stud is to be placed. 



Frame the rear wall and set it up in 

 place and then place the side wall studdings. 

 Be sure that the walls are square, plumb 

 and well - braced. Next set the roof 

 rafters. They are 8 ft. long and are 

 of the same kind of material as that used 

 for the wall framing. The rafters are 2 

 ft. apart and the floor joists are of the 

 same material. 



When the frame is all up and solidly put 

 together so that it will not rack out of 

 shape, the siding can be nailed on to the 

 framework. For siding, use just the ordi- 

 nary 6-in. flooring lumber obtainable from 

 any lumber dealer in your town. Nail the 

 boards on closely and be sure not to leave 

 any cracks. A draft is a dangerous thing in 

 a chicken coop. The bird that catches cold 

 soon passes out of the profit-making class. 

 The walls of the house, the roof and the 

 floor are all to be covered with this same 

 kind of lumber. For the coop 300 ft. of 

 flooring boards will be required. Make the 

 door out of the same kind of stuffs and use 

 6-in. boards for cleats and braces. The 

 door will hang on 6-in. strap hinges. Leave 

 the proper opening for the window sash 

 which is 3 ft. by 43^ ft., as is shown in the 

 framing diagram of the front. The opening 

 for the door is 23^ ft. by 6 ft. in height. 

 The illustration of the completed colony 

 poultry house shows how the sashes are 

 hung for ventilation. They are pivoted at 

 the top and all are fastened to a rod so that 

 the opening can be regulated to any desired 

 degree. These are just the ordinary cellar 

 sashes that are carried in stock by lumber 

 dealers. There are three lights in each 

 sash; the glass measures 10 by 12 in. for 

 each one of the panes. The following is a 

 list of materials for the poultry house: 



2 pes. 4 in. by 4 in. 9 ft. long for skids or runners 



4 pes. 2 in. by 4 in. 8 ft. long for sills (front and rear) 

 4 pes. 2 in. by 4 in. 6 ft. long for sills (sides) 

 8 pes. 2 in. by 4 in. 7 ft. long for front wall studding 

 8 pes. 2 in. by 4 in. 5 ft. long for rear wall studs 

 4 pes. 2 in. by 4 in. 6 ft. long for side wall or end 



studs 



4 pes. 2 in. by 4 in. 8 ft. long for top plates (front 



and rear) 



5 pes. 2 in. by 4 in. 6 ft. long for floor joists 

 5 pes. 2 in. by 4 in. 8 ft. long for roof rafters 



4 pes. I in. by 4 in. 8 ft. long for eorner finish boards

To Prevent the Comers of a Rug 

 From Curling 



HERE is a simple plan for preventing 

 the corners of rugs from curling up. 

 Cut four pieces of whalebone or corset steel, 



Simply made stiffener to hold rug comers 

 down fiat on the floor and prevent curling 



each about 4 in. or 5 in. long, also four 

 strips of adhesive tape a little longer. Turn 

 the rug over and lay the whalebone in place 

 as shown and fasten it down with the tape, 

 pressing hard so that the edges will adhere 

 firmly to the rug to keep the stiffening 

 material in place. — J. E. McCoy. 



A Multiple Tool Boring-Bar for 

 Machinists' Use 



OF unusual strength, compactness and 

 perfect self-centering ability is the new 

 milling and boring tool shown here, which 

 is cornmanding considerable attention from 

 machine-shop men. Rapid and clean bor- 

 ing work in a small shop or garage formerly 

 had to be done by a single point tool or 

 cutter — multiple point tools being either 

 too large or too expensive for a small shop. 

 When a single point tool is used, it is 

 necessary to correct the chatter, the irregu- 

 larities due to eccentricity, especially when 



Self-centering multiple cutter boring tool 

 which can be inserted in ordinary drill-chuck 



operated at a fairly high speed. The 

 simple arrangement shown in the accom- 

 panying illustration obviates all difficulties. 

 The illustration is practically self-explan- 

 atory. Given such a cluster of tool bits, 

 set in a conical socket adjustable by a 

 single central thread, the result is a self- 

 centering tool of variable diameter.
