Excluding only leading or trailing cells from a column

You've explained about excluding the leading cells A1:A3 but what do you
mean when you say exclude trailing cells? What trailing cells?

I have a column, say A, that I want to SUM(). I want to avoid including
A1:A3
in this sum - unfortunately, the length of the data in the column at any
time
is indeterminate. So I can't SUM(A4:AX)... And I can't SUM(A4:A), although
that seems intuitive to me.

Help?
