��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

��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.
