How do you use Excel 2007 to take the logarithm of a whole column of numbers?

I have a column of positive numbers and want to take the natural log of each. I know how to do this for each individual number... but how do you get Excel to do it for the entire column automatically?

Please give me the sequence of commands or steps in detail. Thanks in advance.
