I added a picture to this poem, so that you would have a better sense of the scene that prompted this reflection. You'll have to go to the main page to see it, though. 

Fresh snow coats the spiky crowns of evergreens

into narrow cones of shining white

steepled against a brillig sky -- 

a vast convocation 

of pointy white hoods.

Do spruce trees also

have pointy little brains

beneath their whited hoods?
