I will perform the function of a whetstone, which is about to restore sharpness to iron, though itself unable to cut.
[Lat., Fungar vice cotis, acutum
Reddere quae ferrum valet, exsors ipsi secandi.]
Receive, dear friend, the truths I teach,
So shalt thou live beyond the reach
Of adverse Fortune's pow'r;
Not always tempt the distant deep,
Nor always timorously creep
Along the treach'rous shore.
Often turn the stile [correct with care], if you expect to write anything worthy of being read twice.
[Lat., Saepe stilum vertas, iterum quae digna legi sint Scripturus.]
