The demand for December, 1909, 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 com- 

 plete.
