Maine Blueberry Cake

Ingredients
2 cups blueberries  
1/2 cup butter 
1-1/2 cups sugar   2 eggs, beaten  
1/2 cup sour milk   1/2 t. baking soda 
2-1/2 cups flour (add 1/2 cup of this to blueberries)   


Directions
ED: I assume you mix this all together and then...
You got me!
I wonder if you toss the blueberries in a half cup of the flour.
And then you make the cake batter with the sugar, eggs, sour milk, baking soda, and the rest of the flour.
Then maybe, right before you pour it into the dish, you fold in the blueberries.
Put in a greased, 9 x 13 dish???
Sprinkle lightly with sugar for crust.
Bake for 40 to 45 minutes at 350°.
