The sketch shows a simple bed bolster which I have made and which can be constructed at very little cost. Three circular pieces of poplar or pine, 10 1/2in. in diameter, are required. These may be made in one cut by nailing the pieces together. Then nail on ten % by 2-in. strips, 52 in. long, or as long as the width of the bed, leaving about 1/2 in. space between the strips. These strips will thus go about two-thirds of the way around the circle, leaving room to insert the pillows when the bed is not in use. Cover the bolster with building paper or any other suitable material, and it is ready for the pillow shams. - Contributed by C. Martin, Jr., Chicago.
