Lorick #74:

Plain enough to behold it is true;

it's important how used, and by who.

A container of sorts

-- its pursuit, holy sport!

Over time its repute only grew...

But first, we solve #75 - here it is one last time:

I speak of a tree on an island;

Annotated in red by a neat hand.

My three crimson marks

ignite feverish sparks

in brains where desire's green flames fan!
