Gas mask. 

I doggedly dig i allegedly dug a dog 

that digs called in from the cold frame

hole to get the blood and bone 

from whence it was and whence it came.

.

at once i gladly roared at lions on tins 

to sit by fire toasting hands Cupping ginger 

Burning the overs in tapered paper wire.

.

whilst wearing gas mask detecting leaks 

to save the fallen wild rock in Belgian 

chimneys bathed in orange and mauve.

.

the double needles blank seven 

Dubious twelve.
