It's been all quiet for several days now, so I thought it was time for the solution. Believe it or not, a Mabel Barnicott managed to get the solution correct "in every respect"! (How on earth did she know about the brackets?!)
I've been waiting for May all the winter through;
(And the winter is long in the North Countrie)
But the bulbs have sprung forth; and I daily view,
In the sun-lighted distance, the deep blue sea.
Oh Crown Imperial, O tulip proud,
My loving heart just laughs out loud!
It is blithe when it all-that-it-longed-for gets;
(But the summer is short in the North Countrie)
We must hastily take drear old Winters's debts,
And hug to our heart and memory,
The Iris, snowflake, and wall-flower sweet;
For spring-time days have footsteps fleet.
The Examiners' Report makes very entertaining reading too. You can read it here
