The tints of Las Cañádas, seen from above, are the tenderest yellow and a brownish red, like the lightest coat of vegetation turning ruddy in the sun. Where level, Las Cañádas is a floor of rapilli and pumice-fragments, none larger than a walnut, but growing bigger as they approach the Pike. The colours are dun (barriga de monja) , golden-yellow, and brown burnt red like autumnal leaves. There is marvellous colouring upon the bluffs and ridges of the rim--lamp-black and brown-black, purple (light and dark) , vermilion-red, and sombre hues superficially stained ruddy by air-oxygen.

These flats of pumice, 'stones of emptiness,' loose incoherent matter, are the site of the first great crater. Tenerife is the type of a three-storied volcano, as Stromboli is of one and Vesuvius of two stages. The enormous diameter of this ancient feature is eight by seven miles, with a circumference of twenty-three--greater even than Hawaii--and here one feels that our earth was once a far sublimer scene.

Hence the puffs of vapour seen from below against the sparkling blue sky, and disappearing like huge birds upon the wings of the wind: hence, too, the tradition of the mast and the lateen sail. A dig with the Guanche magada or lanza, the island alpen-stock, either outside or inside the crater, will turn up, under the moist white clay, lovely trimetric crystals of sulphur, with the palest straw tint, deepening to orange, and beautifully disposed in acicular shapes. The acid eats paper, and the colours fade before they leave the cone.
