The Month Scale 

When storms' darkening
in the skies of May
when the pane's leaking 
under skies of June
when aged pealing
of the skies July
when storms screaming
which push August
when waltz swimming
of the month September
when cream is raining
of fumes in October 
when clouds are melting
on Toussaint November
when do flow raging
the snows of December
when wise drooling
on threads January
when good's coming
short February
when wild's shortening
of course relates March
when coming's breeding
finish in April
when storms' darkening
in the skies of May
year's recommencing
to infinity
