FIGURE 1. Upper half showing method of fastening 

 nesting-box to top of wooden pole. A step of the same 

 depth as the thickness of the board forming the back of 

 the box, and long enough to extend well up the back and 

 ensure stability, is cut on the side of the pole at its top. 

 The lower edge of the box will rest upon this. Fasten 

 firmly with wood screws, one in front, through the pro- 

 jecting back-board, and two in back through holes bored 

 in pole to prevent splitting. 



FIGURE 1. Lower half showing manner of fastening 

 pole to fence post or stump of tree. Lag screws are used 

 on account of the extra strength needed and of course 

 must be driven by means of a wrench. Bore the holes for 

 these large enough to allow the lag screws to go through 

 the pole without splitting it. In the post itself, do not bore 

 the holes too deep. Just start the hole and then set up the 

 lag screws firmly with the wrench until all the loose play 

 is taken up. 



FIGURE 2. Left-hand drawing showing nesting-box 

 mounted on iron pipe. Right-hand drawing showing bot- 

 tom of box with the flange or plate, threaded for pipe, 

 firmly screwed on. If preferred, the flange may be dis- 

 pensed with and the end of the pipe flattened on an anvil, 

 holes drilled for screws about six inches apart and the 

 box fastened in the same manner as described for the 

 wooden pole except that the step for bottom of box to rest 

 upon is eliminated.
