Love for a quarter

CJ turns 73 next week. His brother, Judson, just turned 85. Judson found a yellowed note that he sent to his father on the occasion of his little brother's birth, in the depression in Missouri:

Dear Daddy,

Since the baby has come I know we are under circumstantial problems. I am provided with well enough and think I could get out the ashes and coal for nothing.

You put the extra quarter in on anything the boy would kneed.

Your son,
Judson
