PURCHASING BUREAU. 



/^ New Department for Ornithologists 

 and Oologists, 



The NiDiOLOGiST has established an agency for 

 the sale of skins, eggs, birds, scientific literature, 

 etc., which will prove very valuable to reliable 

 collectors who desire to dispose of specimens for 

 cash, and to owners of collections who wish to 

 secure desiderata. 



None but strictly reliable collectors, offering first 

 class authentic specimens, will be privileged to use 

 this column. We hold ourselves responsible for 

 the protection of both buyer and seller. 



Cash must accompany all orders, which we will 

 hold until eggs or other articles are received in 

 condition satisfactory to purchaser. Seller must 

 pay transportation unless otherwise stated. This 

 is a good thing. Try it and see. Send us your list 

 of first-class specimens and lowest price post paid 

 Wfc will advance price sufficiently to pay tor adver- 

 tising and trouble. No charge if no sale is effected.

 K(;<;s OF California Mi;ure sent, post paid, at 3 

 for $0.50, 7 for $0.90; per dozen, $1.50. S|)ecial at- 

 tention is called to the fact that these are carejiilly selected 

 •_;gs, showing all tlie beautiful colors and curious mark- 

 ugs. \ large or small series is indispensible to every 

 collection, and al tliis low rate it is the best kind of an 

 investment. Collectors will not, as a rule, exchange 

 these eggs, on account of lrans])ortation. Four oi- five 

 dozen Murre's eggS is not too many for series, and you 

 will be surprised at the variety of shades and markings 

 hown in one dozen. Order at once.
