This is a Secondary Heading Secondary headings are flush left on the page. Each word is capitalized, and the heading is underlined. Text under a secondary heading begins a new paragraph. This is a tertiary heading . Tertiary headings are indented and end with a period.
Text follows after the period.
Only the first word of the heading is capitalized. Use headings judiciously, where they will improve the readability or organization of your paper. Too many headings disrupts the flow of your paper, while too few headings robs the paper of crispness. As a general rule, you should not employ a particular level of heading in a section of text unless you will need at least two headings of that type. For example, if you have used a secondary heading, and you are wondering whether you should use tertiary headings beneath it, use tertiary headings only if you will need two or more of them under the secondary heading.
