He has placed 500 spiles - or taps - on somewhere in the neighborhood of 175 trees.

They hammered sharp little drippers they called spiles into the holes.

Then they drilled holes in the chosen sugar maples and hammered in the taps, or spiles.

After my father died, I didn’t know what happened to the handful of spiles he had.

English regional words for a small piece of wood under the skin such as "spool", "spile", "speel", "spell", "shiver", "spill" and "splint" are falling out of use in favour of "splinter".
