I send you copy of chart, which, though not quite complete (new things are added nearly every day) will give an opportunity to see at a glance, something of the condition of affairs, and will serve as something like a duplicate record in case of accident to original records.

We are keeping more thorough records than ever before. Mistakes are perfectly human but we are trying to keep them out as much as we can.

Each man keeps a book in which he charts and catalogues all the bones he takes out.
