Anagrammatical Epigram

On passing under the stern of the Gorgon 44 Gun Ship

Terrific name! who’ll dare come near thee
Friends as well as foes must fear thee
Gorgon! thy enemies will cry
And from thy winged bullets fly
While friends thy name will backward read
And from thy thirsty bark recede.
For thus, exclaims each waggish dog
I’ll board no ship where there’s No Grog

My first in French is always bad,
My next appears with snow,
My whole is what you never had,
And may you never know.
