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 

 ^1 step which will protect every purchaser directly

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

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

 accordingly. 



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

 tip any sort of nesting-box, but one that carries out the established 

 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 

 obtain similar results to his. Success in protecting birds depends 

 on apparent trifles, such as Nature prescribes for us. Only the two 

 firms of Scheid and Bertschinger work under the immediate and direct 

 supervision of Baron von Berlepsch (Bertschinger, as we said before, 

 makes the boxes only, and we especially draw attention to the fact that
