I hope most of you already have on your calendar Open House on September 30 from 2:30 to 4:30 at Historic Oak Grove School. Just in case, I'm including an invitation just for you!
In researching and preparing for the restoration, as well as, the open house, I discovered that Bertha Cox was the school cook, and she was a good one. Students loved her Raisin Squares, and if you come to Open House you should get to sample some of these cookies. Just in case you want to try a batch, here is Bertha's recipe:

Bertha Cox Raisin Squares

2-1/2 cups raisins
1-1/4 tsp. cinnamon
1-1/4 cups water
1-1/4 cups white sugar
2-1/3 cups brown sugar
1-3/4 cups Crisco
2 tsp. vanilla
3-1/2 cups self-rising flour
4 cups oatmeal (not 1 minute)

Mix raisins, water, cinnamon
and white sugar and cook for about
10 minutes.

Cream together brown sugar, Crisco
and vanilla. Then add flour and oatmeal.
Mix to a crumbly mixture
and spread ½ this mixture into a greased
9 x 13 pan.
Spread raisin mix on top.
Spread remainder of the crumbly mix on
top of raisin mix.

Bake at 350 degrees F. for about 25 minutes
Ovens vary, so check doneness in your own
oven.

Cool and cut into one inch squares.

Enjoy!
