Summary

Garland Greever The Century Handbook of Writing

The colloquial sentence It was a cold day but there wasn't any wind blowing is a loose string of words. Written discourse requires greater tension and more care in subordinating minor ideas: The day, though cold, was still. Contractions are proper in conversation, and in personal or informal writing. In formal writing they are not appropriate. And do not let such expressions as He doesn't, We aren't, It's proved, used in talk by careful speakers, mislead you into expressions like He don't, We ain't, It's proven, which violate even colloquial good use.

We do not see the stars at evening, sometimes because there are clouds intervening, but oftener because there are glimmerings of light; thus many truths escape us from the obscurity we stand in, and many more from the state of mind which induces us to sit down satisfied with our imaginations and of our knowledge unsuspicious. [This sentence is correctly balanced, except at the end.]
