It might, certainly, if the fact be true.  Moreover, Mr. Joseph does not seem to be aware that the old Spanish Conquistadores had a myth that music was to be heard in this very Gulf of Paria, and that at certain seasons the Nymphs and Tritons assembled therein, and with ravishing strains sang their watery loves.  The story of the music has been usually treated as a sailor’s fable, and the Sirens and Tritons supposed to be mere stupid manatis, or sea-cows, coming in as they do still now and then to browse on mangrove shoots and turtle-grass:  {110} but if the story of the music be true, the myth may have had a double root.

Meanwhile I see Hardwicke’s Science Gossip for March gives an extract from a letter of M. O. de Thoron, communicated by him to the Academie des Sciences, December 1861, which confirms Mr. Joseph’s story.  He asserts that in the Bay of Pailon, in Esmeraldos, Ecuador, i.e. on the Pacific Coast, and also up more than one of the rivers, he has heard a similar sound, attributed by the natives to a fish which they call ‘The Siren,’ or ‘Musico.’  At first, he says, he thought it was produced by a fly, or hornet of extraordinary size; but afterwards, having advanced a little farther, he heard a multitude of different voices, which harmonised together, imitating a church organ to great perfection.  The good people of Trinidad believe that the fish which makes this noise is the trumpet-fish, or Fistularia—­a beast strange enough in shape to be credited with strange actions:  but ichthyologists say positively no:  that the noise (at least along the coast of the United States) is made by a Pogonias, a fish somewhat like a great bearded perch, and cousin of the Maigre of the Mediterranean, which is accused of making a similar purring or grunting noise, which can be heard from a depth of one hundred and twenty feet, and guides the fishermen to their whereabouts.

How the noise is made is a question.  Cuvier was of opinion that it was made by the air-bladder, though he could not explain how:  but the truth, if truth it be, seems stranger still.  These fish, it seems, have strong bony palates and throat-teeth for crushing shells and crabs, and make this wonderful noise simply by grinding their teeth together.

I vouch for nothing, save that I heard this strange humming more than once.  As for the cause of it, I can only say, as was said of yore, that ’I hold it for rashness to determine aught amid such fertility of Nature’s wonders.’

One afternoon we made an attempt on the other Guacharo cave, which lies in the cliff on the landward side of the Monos Boca.  But, alas! the wind had chopped a little to the northward; a swell was rolling in through the Boca; and when we got within twenty yards of the low-browed arch our crew lay on their oars and held a consultation, of which there could but be one result.  They being white gentlemen, and not Negroes, could trust themselves and each
