MADRID--Educators on a tiny Spanish island off West Africa are resurrecting an ancient system of whistling used by rural folk to communicate across canyons.

The Canary Islands government said recently that the code of peeps and whirs will be a mandatory course in elementary schools on Gomera, the mountainous island where it originated centuries ago, and as an elective in high schools.

No one knows for sure how the system originated. It might have arrived on Gomera with Berbers from the Atlas Mountains of Morocco and Algeria, said Rogelio Botanz, of the Canary Islands education department.

The Gomera version is strictly phonetic, with whistles of different tone or length representing a no-frills alphabet of two vowels and four consonants.

That means lots of words sound similar and are easily confused.

"It's like when you speak over the phone, and the letter S can sound like the letter F," he said.

Still, the system was enormously useful for rural people to communicate on an island of terrain gouged with deep ravines that made short-distance travel difficult.

The system started to die out in the 1940s and 1950s, when Gomera lost much of its population to emigration.

These days Gomera has 12,000 residents, of whom several thousand still know the whistle system, Botanz said.

So far the teaching corps has two members: a shepherd and a farmer. There's one more position to fill. Elementary school students in Gomera will have one 20-minute whistling class a week.

"We've seen children who with just 30 minutes a week become wonderful whistlers," Botanz said.
