Friend or foe? Who went hence?

Begotten of whaleback

in loins of fancy

by a silvery Tay,

prompted by happy night

and restless morning.

Quo Vadis my child,

my dissenting unbeast?
Speak to me if you would

out of friendly fire

with whaling industry

and of textile towns.

Anything, any thing,

any damn blessed thing?

There lay carved initials.

Friend or fiend? Who went hence?
