The new catalogue lists 807 species 

 and 398 sub-species, 1205 in all. All 

 but 73 are valued whereas in the old 

 list we find 168 unpriced. The 1132 

 priced, range from 10c to $750.00. Let 

 us assume we have a set of 4 for each 

 specie — our collection would have a 

 list value $2624.00. As we still have 

 73 eggs unpriced let us assume that 

 for a grand total we have $30,000.00— 

 which will not be any too high valu- 

 ation. A third of this or $10,000 

 would be somewhere near the cash 

 value. 



The average value of an egg in the 

 new list is $5.00 as against an average 

 value of $2.35 in the 1905 catalogue. 



Eggs have therefore advanced over 

 100% in value (exchange value). Only 

 27 remains at 10c, while 37 are priced 

 above $25.00. 



Following is a list of the first 

 twelve: 



California Condor $750.00 



Passenger Pigeon 100.00 



Ivory-billed W 100.00 



Spoon-billed Sandpiper 60.00 



Black Swift 75.00 



Trumpeter Swan 50.00 



Heath Hen 50.00 



Blue-throated Hummer 50.00 



Whooping Crane 45.00 



Hudsonian Godwit 35.00 



Swallow-tailed Kite 35.00 



Evening Grosbeak 35.00' 



How many have a set from this 

 select group?

OLD KENTUCKY BIRDS 



The April issue of The Oologist is 

 indeed a welcome and decidedly valu- 

 able edition. With reference to the 

 Brown Thrasher, I have a record of 

 twelve occupied nests upon the 

 ground. All but one of these was dis- 

 covered while searching for Wood- 

 cock during month of April in North- 

 ern Illinois and Indiana. The excep- 

 tion was a nest under an oak shrub 

 on hillside at Long Lake, Hillsdale 

 County, Michigan, July 1, 1896. 



I have one splendid photo of an in- 

 cubating Thrasher on nest under haw 

 bush. Most of these ground nests 

 were built flush with the surface and 

 the preferred sites consisted of hilly 

 ground, dotted with patches of hazel, 

 sumach and haw. 



At this writing I have four young 

 Thrashers two weeks old, in a nest 

 within eighteen feet of my dwelling. 

 Last year's nest (still intact) is in 

 the same climbing rambler rose bush 

 and just eleven inches from the 1922 

 domicile. 



In our revolving chain pump just 

 outside the door is a Bewick's Wren 

 which does not manifest any alarm 

 when we "lift" water over her feather 

 lined nest, on the ventilating screen. 

 She is covering seven evenly dotted 

 specimens, size between those of the 

 House and Carolina Wrens. 



A Catbird is building in the trumpet 

 creeper along the back fence and the 

 Cardinal chose the grape arbor for a 

 home. The latter is "sitting close." 



Many people raise chickens on the.r 

 premises and distribute poisoned meat 

 for rats under rocks and plants about 

 the coops. This practice has proved 

 fatal to several inquisitive Blue Jays.
