For a long time the mystery connected with the virulent poison, known as curare, urari woorali, etc., with which the Indians poison their arrows, remained unsolved, notwithstanding the efforts of men of science to determine its source and composition. Early travelers gave the most fantastic accounts of its composition and manufacture. According to them it was a concoction more uncanny than that prepared from

“Eye of newt and toe of frog,

Wool of bat and tongue of dog.

Adder’s fork and blind worm’s sting,

Lizard’s leg and owlet’s wing.”

Indeed, so carefully did the Indians engaged in its manufacture guard the secret of its preparation that it was not until a few decades ago that the true character of this deadly compound was first understood. Boussingault suspected but did not prove the existence of strychnine in curare.[4] Humboldt was probably the first to suspect its true nature.[5] It is now known that neither snake’s teeth nor stinging ants form its active principle, as was formerly supposed, but that its venomous properties are due to the presence of curarine, a bitter crystalline alkaloid obtained from the plant Strychnos toxifera, or other plants of this genus, found throughout equatorial America. Its virulence is manifested only when it is administered through the skin. It then paralyzes the motor nerves, and, if the poison be sufficiently strong, it produces death by suffocation.

The Indians in Orocué, as everywhere else along the Meta and Orinoco, were a subject of never-ending study for us. Most of the inhabitants of Orocué are Indians or mestizos, and it would be difficult to find anywhere a gentler or more peaceful people. The town was founded by the Salivas Indians, whose nasal language the early missionaries found so difficult to master, but whose gentle nature and amiable disposition were ever the subject of the highest eulogies. Remnants of this tribe are still found in this territory, as are also representatives of the Piapocas, Tunebos, Yaruros, Cuivas, and the once powerful yet friendly Achaguas.

The tribe, however, that counts the greatest numbers, is the Guahibos, whom certain imaginative travelers would have us believe are as fierce as pumas or jaguars. The truth is, however, that, although some of them are more or less nomadic in their habits, and decline to live with the racionales—whites—they are, as a rule, peaceful and industrious. Sr. Jorge Brisson, an engineer for the Colombian government, who a few years ago thoroughly explored this country—the Casanare—speaks of them as being muy agricultores y muy trabajadores—hard-working tillers of the soil.

That they are peaceful and harmless is evidenced by the fact that the owners of the scattered conucos along the Meta are rarely, if ever, disturbed by these much maligned Indians. In many of the isolated habitations, which we visited on our way up the river, we found only women and children. The men were occupied elsewhere, and were sometimes absent for weeks at a time. This, certainly, would not be the case if the Guahibos were the cruel, relentless savages they are so often represented to be. Not once in our journeyings up the Meta and its affluents did we hear of any atrocities committed by these Indians, or even of any complaints against them, although we took particular pains to inform ourselves about the matter. All the reports about their robberies and murders were confined to those we had heard a thousand miles down the river and from people who probably never saw a Guahibo in their lives, and who would not recognize one if they were to see one.

It is true that now and then a cow or a calf may disappear from some of the Conucos and fundaciones and that their disappearance is always credited to the Indians. Even if this suspicion were verified, an occasional theft of this kind—all the circumstances considered—should not be so surprising. We do not need to go beyond the boundaries of our own country to find cases of cattle stealing. And the poor Indian, often cheated and wronged, may, without being a casuist, easily persuade himself that he is justified in seeking occult compensation. This is often his only safe method of making reprisals for damage done him in person and property, and he would be more than human, if he did not occasionally resort to it if he thought he could do so with impunity.
