The Mystery of the Morrow Hill Tunnels

I wonder if anyone knows anything about Morrow Hill and its mysterious tunnels.  Correspondent Bill Bennett has sent a poem written in the early 1900’s that raises a lot of questions . . .

The Morrow Hill Tunnel
 – by Mrs. Mary Morrow

When the winter snows are thawing,
and the sun is shining clear,
and the thievish Crow is cawing,
then we know the spring is near.

When from every house and hovel,
water runs in many a rill,
You will find some men with shovels,
digging in the Morrow Hill.

Men who have some occupation
take a day off to go there,
also some who have vacation
from the winter’s lumbering care,

And many a good round dollar,
as they labor with a will,
they earn with a sweating collar,
making tunnels in the hill.

If you wish to travel through it,
you had better have a care,
someone else may come to view it,
and you’ll have a meeting there.

You will be of good sense lacking,
if you do not whistle shrill,
you may have to do some backing,
in the tunnel in the hill.

With these snowbanks to surround you,
every shade from black to white,
and the labyrinth confounds you,
makes you almost feel affright.

Now this work is quite laborious,
and we think our men of skill,
should yet circumvent old Boreas,
at the tunnel in the hill.

Bill says Mrs. Morrow was a distant relative, grandmother to his cousin George Morrow.  Morrow Hill was the name given to the steep rise located northwest of the intersection of M-88 and Meggison Road.  Bill wondered what these men with shovels were doing in the tunnel.  Then he remembered that his father told him that years ago the farmers would bury potatoes in the sand where they would stay dry.  The snow would come along early enough that the ground where the potatoes were buried would not freeze.  Bill thinks the poem “is actually about farmers digging and/or burying potatoes in this rather mysterious place.”  Hmm.  Maybe.  But it sounds like something more than potatoes was on the minds of those men.  A gold rush in Antrim County?  A hidden still!  A railroad scheme?  A subway!  What do you suppose it was all about?  Anybody know?
