Sonnet LXXVIISonnet LXXVIIThy glass will show thee how thy beauties wear,

Thy dial how thy precious minutes waste;

The vacant leaves thy mind's imprint will bear,

And of this book this learning mayst thou taste.

The wrinkles which thy glass will truly show

Of mouthed graves will give thee memory;

Thou by thy dial's shady stealth mayst know

Time's thievish progress to eternity.

Look, what thy memory can not contain

Commit to these waste blanks, and thou shalt find

Those children nursed, deliver'd from thy brain,

To take a new acquaintance of thy mind.

These offices, so oft as thou wilt look,

Shall profit thee and much enrich thy book.
