There are names down the left-hand side, and years across the top of the page. When the pensioner died, there is usually a note about the death date and how long the pension was paid.
The line with Mary Row on it is:

So now I have a death date for a widow of one of my Revolutionary War soldier. I never thought I would get an exact date. It looks like the family kept receiving the pension until 1850!
Mary (Smith) Row lived to be almost 93 years old. I wish I could have sat at her knee and listened to the stories of her life. I might even have found out the name of her parents! She was one of my 4th great-grandmothers.
Now I need to look for records for my other Revolutionary War pensioners.
