Hi Myra -
The forms used were periodically changed - so you'll need to find
someone who either knows exactly when the forms changed, or someone
with a page >from the same month and year, to know what the format was.
I would also suggest checking out the NARA website - perhaps they have
a description of the forms used in 1906. The ones I have are >from
1904 and 1921 and the column headings are somewhat different.
