 a little while the birds showed no marked prefer- 

 ence for these boxes, but by and by he found 

 that he got most interesting results. Birds 

 which had never come to any of his other nest 

 boxes came to these, and the birds which had 

 always come to the other kinds liked the new 

 ones at least as well. He once put up two 

 thousand of these nest boxes, and seventeen

 pressed with the result of this and other experi- 

 ments of the Baron's that it has established other 

 bird sanctuaries in other parts of Germany. 

 The Grand Duchy of Hess, not long ago, put up 

 40,000 of those nest boxes in the forests to pro-
