single state of Iowa. <A single stomach contained 700 seeds 
of pigeon-grass. Couple with this the weed seeds destroyed 
by the many other equally valuable native species of Spar- 
row found abundantly in Iowa and North Dakota and we 
have a grand total which means an inealeulable saving to 
the people of the state. 
The examination of 725 stomachs of the Red-winged 
Blackbird showed 74 per cent was vegetable matter mostly 
weed seeds, while the remainder consisted largely of wee- 
vils and grasshoppers. The stomachs of Mourning Doves 
contained 64 per cent of weed seed for the entire year in- 
eluding such pests as pigeon-grass, rag-weed and smart 
weed. One stomach alone contained 6,400 seeds of fox-tail 
erass. The stomach of a Snow Bunting contained 1000 pig- 
weed seeds. A long list of valuable birds might be enumer- 
ated here, but those who are interested are urged to make 
their own observations in the field throughout the year and 
study the literature listed beyond.

National and State Game and Bird Reservations. 
(a) Stump Lake, N. Dak., is a national reservation 
‘in the midst of the breeding grounds of several species of 
ducks and is the only point at which the white-winged 
seoter is known to breed in the United States.’’ Large 
numbers of other shore birds and water fowl also rest and 
nest here. Alf. Eastgate of Tolna is the warden in charge.
