of the boxes is much the same, but what do we find when we compare 

 the interior, the boring, position of the opening, etc. ? At the bottom 

 of one box there is such a lump that it could not possibly be 

 inhabited by any bird. The box is very carelessly wrought in other 

 respects. It is hollowed out, as the illustration shows, to the outer 

 shell, so that the wall could be pressed in by the finger, and the 

 boxes on the right show distinct signs of dishonest workmanship. 

 They also seem correct from the outside : size, opening, everything 

 coincides. Here is box B for starlings, but pierced with the same 

 borer as A — the box for tits. It is simply a fraud, for the birds for 

 which it is intended cannot get in at all. The Commission sent for 

 three specimens of each of these boxes. Those shown here are the 

 worst, it is true, but the others were not much better. It is very plain 

 that the unfortunate owner of such a box has little to hope for 

 from its use. 



These are only two instances out of many, so that we need not be 

 astonished that there are still so many failures. Fortunately, we are 

 still in a position to attack this dishonest way of doing business by a

It is therefore to the interest of every purchaser to make use of 

 only such nesting-boxes and other appliances for the protection of birds 

 as bear this trade-mark. The " Commission for Encouraging the 

 Protection of Birds " urgently requests all who are interested to act 

 accordingly. 



It is time that people realized that it is not a question of hanging 

 up any sort of nesting-box, but one that carries out the estabhshed 

 principles in every detail, i.e., which corresponds in the minutest detail 

 with a natural woodpecker's hole. If this were not so it would seem 

 strange that before Baron von Berlepsch took up the matter we did not
