inches above r. Now draw out the nails, saw out r and s, 

 and use the two pieces i and j for patterns. For h take a 

 six-inch board four feet long and at the middle of each 

 side saw out a notch one inch deep and 2y 2 inches wide. 



After having sawed out a sufficient number of pieces ac- 

 cording to Figure B, then proceed to put them together 

 as in Figure B'. Saw out a piece, x, \7y 2 inches long, 2 

 inches thick and 2y 2 inches wide. Nail this on the table 

 so that its median line is perpendicular to the base line at 

 1, and so that the upper end is 28>y 2 inches from the base 

 line. Now prepare two blocks, y and z, of one-inch lum- 

 ber and nail them to the table so that the outside lower 

 points, as in Figure B', are each 21 inches from the point 

 1. Place i, j and h in the position as in Figure B' so that 

 the inside notches of i and j will rest firmly against the 

 upper end of x, and that .the notch on the upper side of h 

 will rest firmly against the lower end of x and that h is 

 parallel to the base line. Nail firmly and saw the corners 

 of h so that it is flush with i and j. The upper ends of y 

 and z have nothing to do with determining the lower line 

 of h. Use 8d wire nails and clinch. 



Both the triangles and panels should be made of com- 

 mon rough fencing and the number of triangles should 

 equal the number of panels plus one. In placing the 

 panels and triangles to make a fence, reverse every alter- 

 nate panel so that the crossbars are on opposite sides and 

 set a triangle at every juncture of the panels and at the 

 ends of the fence.
