most other birds have become quiet for the night. Then its 

 song breaks forth from all parts of the field and the devout lis- 

 tener exclaims, "This is the Vesper Service of the birds." 



The first brood hatches early in May just when the farmer 

 is plowing his fields for his crops. Many nests with their bird- 

 lings are then buried under the sod. The second brood comes 

 out in July and some of these are crushed under the wheels 

 of mowing machines and reapers. Thus great numbers of 

 the young are accidently destroyed every year, more perhaps 

 than of any other kind of bird. 



To all the dangers that surround the life of other birds, 

 is added for these birds, those that come from the free use of 

 modern farm machinery. Fortunately,; the rearing of two 

 broods in a season helps in a measure to prevent the destruction 

 of this species.
