and 4 inches square at the top, reinforced with four £-inch diameter 

 round rods. It will be seen from Fig. 125 that at a distance of about 

 12 inches from the top of the straining post an indent 1 inch deep 

 has to be provided when moulding the post in order to take the end 

 of the strut, as shown. The width of this indent must, of course, 

 correspond with the width of the strut. Usually the indent is only 

 required on one side of the post, but for corner and intermediate

strainers which have to be strutted on two sides two indents will be 

 required. Gateposts also require a second indent, but in this case 

 the indent has to be below ground level. (See Type " D," Fig. 125.) 



In the case of posts for wire fencing, the holes for the wires may 

 be formed by inserting rods (very slightly greased), horizontally, through 

 holes in the divisions of the mould between each post. These rods are 

 withdrawn as soon as the concrete has set sufficiently to retain its 

 shape.
