The Demand for December, 1 909 



BIRD-LORE 



has so exceeded our estimate that, in spite of 

 the fact that we printed an unusually large 

 edition, the supply is now exhausted. We 

 will, however, send a copy of the Sparrow 

 plate (the first of the series of the Sparrows 

 of North America in color) which appeared 

 in that number to all subscribers to Bird-Lore 

 for 1910 (Vol. XII), in order that their 

 series of these plates may be complete.
